Takashi Iwai be22db77dc ALSA: usb-audio: Fix uninitialized variable at __uac_clock_find_source()
The cur variable indicating the currently selected clock source can be
theoretically used as uninitialized after the recent commit
481f17c418 ("ALSA: usb-audio: Handle error for the current selector
gracefully").  For addressing it, initialize it before use.

Also, one place seems setting 0 to a wrong variable ret, instead of
cur; otherwise it makes little sense.  Since the initialization is
done beforehand, we can get rid of this line, too.

Takashi Iwai 05ca447630 ALSA: line6: Fix racy initialization of LINE6 MIDI
The initialization of MIDI devices that are found on some LINE6
drivers are currently done in a racy way; namely, the MIDI buffer
instance is allocated and initialized in each private_init callback
while the communication with the interface is already started via
line6_init_cap_control() call before that point.  This may lead to
Oops in line6_data_received() when a spurious event is received, as
reported by syzkaller.

This patch moves the MIDI initialization to line6_init_cap_control()
as well instead of the too-lately-called private_init for avoiding the
race.  Also this reduces slightly more lines, so it's a win-win
change.

Takashi Iwai 481f17c418 ALSA: usb-audio: Handle error for the current selector gracefully
Currently we bail out when the device returns an error or an invalid
value for the current clock selector value via
uac_clock_selector_get_val().  But it's possible that the device is
really uninitialized and waits for the setup of the proper route at
first.

For handling such a case, this patch lets the driver dealing with the
error or the invalid error more gracefully, choosing the clock source
automatically instead.

The initialization os usx2y driver is multi-staged, and the PCM and
other device creations are done after the DSP is loaded and

driver tries to call snd_card_free().  But this is dangerous, and in
general, the driver cannot kill itself during its operation.
Hence better to drop the snd_card_free() call from there.

Takashi Iwai 988cc17552 ALSA: usb-audio: Fix implicit sync clearance at stopping stream
The recent endpoint management change for implicit feedback mode added
a clearance of ep->sync_sink (formerly ep->sync_slave) pointer at
snd_usb_endpoint_stop() to assure no leftover for the feedback from
the already stopped capture stream.  This turned out to cause a
regression, however, when full-duplex streams were running and only a
capture was stopped.  Because of the above clearance of ep->sync_sink
pointer, no more feedback is done, hence the playback will stall.

This patch fixes the ep->sync_sink clearance to be done only after all
endpoints are released, for addressing the regression.

Takashi Iwai 316791b556 ALSA: usb-audio: Generic application of implicit fb to Roland/BOSS devices
Through the examinations and experiments with lots of Roland and BOSS
USB-audio devices, we found out that the recently introduced
full-duplex operations with the implicit feedback mode work fine for
quite a few devices, while the others need only the capture-side quirk
to enforce the full-duplex mode.  The recent commit d86f43b17e
("ALSA: usb-audio: Add support for many Roland devices' implicit
feedback quirks") tried to add such quirk entries manually in the
lists, but this turned out to be too many and error-prone, hence it
was reverted again.

This patch is another attempt to cover those missing Roland/BOSS
devices but in a more generic way.  It matches the devices with the
vendor ID 0x0582, and checks whether they are with both ASYNC sync
types or ASYNC is only for capture device.  In the former case, it's
the device with the implicit feedback mode, and applies accordingly.
In both cases, the capture stream requires always the full-duplex
mode, and we apply the known capture quirk for that, too.

Basically the already existing BOSS device quirk entries become
redundant after this generic matching, so those are removed.  Although
the capture_implicit_fb_quirks[] table became empty and superfluous, I
keep it for now, so that people can put a special device easily at any
time later again.

Takashi Iwai fd9db1058c ALSA: usb-audio: Re-apply implicit feedback mode to Pioneer devices
Pioneer devices are supposed to be working with the implicit feedback
mode, but so far the attempt to apply the implicit feedback caused
issues, hence we explicitly skipped the implicit feedback mode for
them.  Recently, Geraldo discovered that the device actually works if
you skip the generic matching of the sync EPs for the capture stream.
That is, we should apply the implicit feedback setup for the playback
like other similar devices, while we need to return 1 from
audioformat_capture_quirk() so that no further matching will be done.

And, later on, Olivia reported later that the fiddling with the
capture quirk alone doesn't suffice for the test with speaker-test
program.  This seems to be a similar case like the recently fixed BOSS
devices.  Indeed, the problem could be addressed by setting
playback_first flag, which indicates that the playback URBs have to be
sent out at first even in the implicit feedback mode.

This patch implements the application of the implicit feedback to
Pioneer devices as described in the above.  The former
skip_pioneer_sync_ep() was dropped, and instead we provide
is_pioneer_implicit_fb() to check the Pioneer devices that need the
implicit feedback.  In the audioformat_implicit_fb_quirk(), simply
apply the implicit fb for playback and set chip->playback_first flag
if matching, and in audioformat_capture_quirk()(), it returns 1 for
skipping the generic EP sync handling.

Takashi Iwai ebe8dc5afb ALSA: usb-audio: Apply implicit feedback mode for BOSS devices
During the recent rewrite of the implicit feedback support, we've
tested to apply the implicit fb on BOSS devices, but it failed, as the
capture stream didn't start without the playback.  As the end result,
it got another type of quirk for tying both streams but starts
playback always (commit 6234fdc1ce "ALSA: usb-audio: Quirk for BOSS
GT-001").

Meanwhile, Mike Oliphant has tested the real implicit feedback mode
for the playback again with the latest code, and found out that it
actually works if the initial feedback sync is skipped; that is, on
those BOSS devices, the playback stream has to be started at first
without waiting for the capture URB completions.  Otherwise it gets
stuck.  In the rest operations after the capture stream processed, we
can take them as the implicit feedback source.

This patch is an attempt to improve the support for BOSS devices with
the implicit feedback mode in the way described above.  It adds a new
flag to snd_usb_audio, playback_first, indicating that the playback
stream starts without sync with the initial capture completion.  This
flag is set in the quirk table with the new IMPLICIT_FB_BOTH type.

covered for the devices with a single connector at the initialization
phase (commit 086b957cc1 "ALSA: usb-audio: Skip the clock selector
inquiry for single connections"), but also there are cases where the
wrong clock set up is kept silently.  The latter seems to be the cause
of the noises on Behringer devices.

In this patch, we explicitly set up the audio clock selector whenever
the appropriate node is found.

Takashi Iwai 5fb45414ae ALSA: usb-audio: Add error checks for usb_driver_claim_interface() calls
There are a few calls of usb_driver_claim_interface() but all of those
miss the proper error checks, as reported by Coverity.  This patch
adds those missing checks.

Along with it, replace the magic pointer with -1 with a constant
USB_AUDIO_IFACE_UNUSED for better readability.

Takashi Iwai 5b1ed7df01 ALSA: control - add generic LED API
This patchset tries to resolve the diversity in the audio LED
 control among the ALSA drivers. A new control layer registration
 is introduced which allows to run additional operations on
 top of the elementary ALSA sound controls.
 
 A new control access group (three bits in the access flags)
 was introduced to carry the LED group information for
 the sound controls. The low-level sound drivers can just
 mark those controls using this access group. This information
 is not exported to the user space, but user space can
 manage the LED sound control associations through sysfs
 (last patch) per Mark's request. It makes things fully
 configurable in the kernel and user space (UCM).
 
 The actual state ('route') evaluation is really easy
 (the minimal value check for all channels / controls / cards).
 If there's more complicated logic for a given hardware,
 the card driver may eventually export a new read-only
 sound control for the LED group and do the logic itself.
 
 The new LED trigger control code is completely separated
 and possibly optional (there's no symbol dependency).
 The full code separation allows eventually to move this
 LED trigger control to the user space in future.
 Actually it replaces the already present functionality
 in the kernel space (HDA drivers) and allows a quick adoption
 for the recent hardware (ASoC codecs including SoundWire).
 
 snd_ctl_led            24576  0
 
 The sound driver implementation is really easy:

    / it calls module_request("snd-ctl-led") on demand /
 2) mark all related kcontrols with

Kai-Heng Feng 44609fc01f ALSA: usb-audio: Check connector value on resume
Rear Mic on Lenovo P620 cannot record after S3, despite that there's no
error and the other two functions of the USB audio, Line In and Line
Out, work just fine.

The mic starts to work again after running userspace app like "alsactl
store". Following the lead, the evidence shows that as soon as connector
status is queried, the mic can work again.

So also check connector value on resume to "wake up" the USB audio to
make it functional.

This can be device specific, however I think this generic approach may
benefit more than one device.

Now the resume callback checks connector, and a new callback,
reset_resume, to also restore switches and volumes.

Note that the problem didn't surface before 5.11 just with luck.
Since 5.11 got a big code rewrite about the stream handling, the
parameter setup procedure has changed, and this seemed triggering the

I overlooked the issue because when I was working on the said commit,
only the front audio is tested. Apology for that.

Changing supports_autosuspend in driver is too late for disabling
autosuspend, because it was already used by USB probe routine, so it can
break the balance on the following code that depends on
supports_autosuspend.

Fix it by using usb_disable_autosuspend() helper, and balance the
suspend count in disconnect callback.

Takashi Iwai 5f5e6a3e8b ALSA: usb-audio: Allow modifying parameters with succeeding hw_params calls
The recent fix for the hw constraints for implicit feedback streams
via commit e4ea77f8e5 ("ALSA: usb-audio: Always apply the hw
constraints for implicit fb sync") added the check of the matching
endpoints and whether those EPs are already opened.  This is needed
and correct, per se, even for the normal streams without the implicit
feedback, as the endpoint setup is exclusive.

However, it's reported that there seem applications that behave in
unexpected ways to update the hw_params without clearing the previous
setup via hw_free, and those hit a problem now: then hw_params is
called with still the previous EP setup kept, hence it's restricted
with the previous own setup.  Although the obvious fix is to call
snd_pcm_hw_free() API in the application side, it's a kind of
unwelcome change.

This patch tries to ease the situation: in the endpoint check, we add
a couple of more conditions and now skip the endpoint that is being
used only by the stream in question itself.  That is, in addition to
the presence check of ep (ep->cur_audiofmt is non-NULL), when the
following conditions are met, we skip such an ep:
- ep->opened == 1, and
- ep->cur_audiofmt == subs->cur_audiofmt.

subs->cur_audiofmt is non-NULL only if it's a re-setup of hw_params,
and ep->cur_audiofmt points to the currently set up parameters.  So if
those match, it must be this stream itself.

Takashi Iwai 21cba9c535 ALSA: usb-audio: Drop bogus dB range in too low level
Some USB audio firmware seem to report broken dB values for the volume
controls, and this screws up applications like PulseAudio who blindly
trusts the given data.  For example, Edifier G2000 reports a PCM
volume from -128dB to -127dB, and this results in barely inaudible
sound.

This patch adds a sort of sanity check at parsing the dB values in
USB-audio driver and disables the dB reporting if the range looks
bogus.  Here, we assume -96dB as the bottom line of the max dB.

Note that, if one can figure out that proper dB range later, it can be
patched in the mixer maps.

The commit 93db51d06b ("ALSA: usb-audio: Check valid altsetting at

set_sample_rate_v2v3() slightly to treat the inconsistent sample rate
as an error.  It was done by assumption that the sample rate
validation should have been done at the parser phase as implemented in
that patch.  But the validation is later selectively enabled only for
certain devices as it causes a regression (the commit fe773b8711
"ALSA: usb-audio: workaround for iface reset issue"), and now the
inconsistency surfaced as a fatal error while it worked in the past as
is, as reported for FiiO M3K DAC.

again to ignore the sample rate difference as non-error.

This patch modifies the state management code to use the atomic int

The state change is done via atomic_cmpxhg() for avoiding possible

Also, stop_and_unlink_urbs() called from release_urbs() does two step

This allows for N different devices to use the pioneer mixer quirk for

	GROUP_MASK	0x00ff0000
	VALUE_MASK	0x0000ffff

This could be improved by changing the arrays of wValues for each
channel to contain named definitions (e.g. SND_DJM_CAP_LINE). It would
improve readability and perhaps would allow using the same array for
multiple channels. The channel number can be specified on the control
next to the wIndex.

Takashi Iwai 506c203cc3 ALSA: usb-audio: Fix hw constraints dependencies
Since the recent refactoring, it's been reported that some USB-audio
devices (typically webcams) are no longer detected properly by
PulseAudio.  The debug session revealed that it's failing at probing
by PA to try the sample rate 44.1kHz while the device has discrete
sample rates other than 44.1kHz.  But the puzzle was that arecord
works as is, and some other devices with the discrete rates work,
either.

After all, this turned out to be the lack of the dependencies in a few
hw constraint rules: snd_pcm_hw_rule_add() has the (variable)
arguments specifying the dependent parameters, and some functions
didn't set the target parameter itself as the dependencies.  This
resulted in an invalid parameter that could be generated only in a
certain call pattern.  This bug itself has been present in the code,
but it didn't trigger errors just because the rules were casually
avoiding such a corner case.  After the recent refactoring and
cleanup, however, the hw constraints work "as expected", and the
problem surfaced now.

For fixing the problem above, this patch adds the missing dependent
parameters to each snd_pcm_hw_rule() call.

Takashi Iwai 532a208ad6 ALSA: usb-audio: Avoid implicit feedback on Pioneer devices
For addressing the regression on Pioneer devices, we recently
corrected the quirk code to enable the implicit feedback mode on those
devices properly.  However, the devices still showed problems with the
full duplex operations with JACK, and after debug sessions, we figured
out that the older kernels that had worked with JACK also didn't use
the implicit feedback mode at all although they had the quirk code to
enable it; instead, the old code worked just to skip the normal sync
endpoint setup that would have been detected without it.  IOW, what
broke without the implicit-fb quirk in the past was the application of
the normal sync endpoint that is actually the capture data endpoint on
these devices.

This patch covers the overseen piece: it modifies the quirk code again
not to enable the implicit feedback mode but just to make the driver
skipping the sync endpoint detection.  This made the driver working
with JACK full-duplex mode again.

Still it's not quite clear why the implicit feedback doesn't work on
those devices yet; maybe it's about some issues in the URB setup.  But
at least, with this patch, the driver should work in the level of the
older kernels again.

endpoint number from the interface descriptor is redundant; we have
already the target endpoint in the given audioformat object.

This patch simplifies the code and corrects the target endpoint as
described in the above.  It simply refers to fmt->endpoint directly.

Also, this patch drops the pioneer_djm_set_format_quirk() that is
caleld from snd_usb_set_format_quirk(); this function does the sample
rate setup but for the capture endpoint (0x82), and that's exactly
what the change above fixes.

Takashi Iwai e4ea77f8e5 ALSA: usb-audio: Always apply the hw constraints for implicit fb sync
Since the commit 5a6c3e11c9 ("ALSA: usb-audio: Add hw constraint for
implicit fb sync"), we apply the hw constraints for the implicit
feedback sync to make the secondary open aligned with the already
opened stream setup.  This change assumed that the secondary open is
performed after the first stream has been already set up, and adds the
hw constraints to sync with the first stream's parameters only when
the EP setup for the first stream was confirmed at the open time.
However, most of applications handling the full-duplex operations do
open both playback and capture streams at first, then set up both
streams.  This results in skipping the additional hw constraints since
the counter-part stream hasn't been set up yet at the open of the
second stream, and it eventually leads to "incompatible EP" error in
the end.

This patch corrects the behavior by always applying the hw constraints
for the implicit fb sync.  The hw constraint rules are defined so that
they check the sync EP dynamically at each invocation, instead.  This
covers the concurrent stream setups better and lets the hw refine
calls resolving to the right configuration.

Also this patch corrects a minor error that has existed in the debug
print that isn't built as default.

Takashi Iwai eae4d054f9 ALSA: usb-audio: Annotate the endpoint index in audioformat
There are devices that have multiple endpoints sharing the same
iface/altset not only for sync but also for the actual streams, and
the audioformat for such an endpoint needs to be handled with the

put the proper ep_idx=1 to Pioneer device quirk entries accordingly.

Takashi Iwai 00272c6182 ALSA: usb-audio: Avoid unnecessary interface re-setup
The current endpoint handling assumed (more or less) a unique 1:1
relation between the endpoint and the iface/altset.  The exception was
the sync EP without the implicit feedback which has usually the
secondary EP of the same altset.  This works fine for most devices,
but it turned out that some unusual devices like Pinoeer's ones have
both playback and capture endpoints in the same iface/altsetting and
use both for the implicit feedback mode.  For handling such a case, we
need to extend the endpoint management to take the shared interface
into account.

This patch does that: it adds a new object snd_usb_iface_ref for
managing the reference counts of the each USB interface that is used
by each endpoint.  The interface setup is performed only once for the
(sharing) endpoints, and the doubly initialization is avoided.

Along with this, the resource release of endpoints and interface
refcounts are put into a single function, snd_usb_endpoint_free_all()
instead of looping in the caller side.

Takashi Iwai 5d15f1eb45 ALSA: usb-audio: Choose audioformat of a counter-part substream
The implicit feedback mode needs to handle two endpoints and the
choice of the audioformat object for the sync EP is important since
this determines the compatibility of the hw_params.  The current code
uses the same audioformat object if both the main EP and the sync EP
point to the same iface/altsetting.  This was done in consideration of
the non-implicit-fb sync EP handling, and it doesn't match well with
the cases where actually to endpoints are defined in the sameiface /
altsetting like a few Pioneer devices.

Modify snd_usb_find_implicit_fb_sync_format() to pick up the
audioformat that is assigned in the counter-part substreams primarily,
so that the actual capture stream can be opened properly.  We keep the
same audioformat object only as a fallback in case nothing found,
though.

Takashi Iwai b2345a8a43 ALSA: usb-audio: Fix the missing endpoints creations for quirks
The recent change in the endpoint management moved the endpoint object
creation from the stream open time to the parser of the audio
descriptor.  It works fine for the standard audio, but it overlooked
the other places that create audio streams via quirks
(QUIRK_AUDIO_FIXED_ENDPOINT) like the reported a few Pioneer devices;
those call snd_usb_add_audio_stream() manually, hence they miss the
endpoints, eventually resulting in the error at opening streams.
Moreover, now the sync EP setup was moved to the explicit call of
snd_usb_audioformat_set_sync_ep(), and this needs to be added for
those places, too.

This patch addresses those regressions for quirks.  It adds a local
helper function add_audio_stream_from_fixed_fmt(), which does the all
needed tasks, and replaces the calls of snd_usb_add_audio_stream()
with this new function.

Takashi Iwai c15871e17f ALSA: usb-audio: Fix possible stall of implicit fb packet ring-buffer
The implicit feedback mode uses a ring buffer for storing the received
packet sizes from the feedback source, and the code has a slight flaw;
when a playback stream stalls by some reason and the URBs aren't
processed, the next_packet FIFO might become empty, but the driver
can't distinguish whether it's empty or full because it's managed with
read_poss and write_pos.

This patch addresses those by changing the next_packet array
management.  Instead of keeping read and write positions, now the head
position and the queued amount are kept.  It's easier to understand
about the emptiness.  Also, the URB active flag is now cleared before
calling queue_pending_output_urbs() for avoiding (theoretically)
possible inconsistency.

Takashi Iwai bf6313a0ff ALSA: usb-audio: Refactor endpoint management
This is an intensive surgery for the endpoint and stream management
for achieving more robust and clean code.

The goals of this patch are:
- More clear endpoint resource changes
- The interface altsetting control in a single place
Below are brief description of the whole changes.

First off, most of the endpoint operations are moved into endpoint.c,
so that the snd_usb_endpoint object is only referred in other places.
The endpoint object is acquired and released via the new functions
snd_usb_endpoint_open() and snd_usb_endpoint_close() that are called
at PCM hw_params and hw_free callbacks, respectively.  Those are
ref-counted and EPs can manage the multiple opens.

The open callback receives the audioformat and hw_params arguments,
and those are used for initializing the EP parameters; especially the
endpoint, interface and altset numbers are read from there, as well as
the PCM parameters like the format, rate and channels.  Those are
stored in snd_usb_endpoint object.  If it's the secondary open, the
function checks whether the given parameters are compatible with the
already opened EP setup, too.

The coupling with a sync EP (including an implicit feedback sync) is
done by the sole snd_usb_endpoint_set_sync() call.

The configuration of each endpoint is done in a single shot via
snd_usb_endpoint_configure() call.  This is the place where most of
PCM configurations are done.  A few flags and special handling in the
snd_usb_substream are dropped along with this change.

A significant difference wrt the configuration from the previous code
is the order of USB host interface setups.  Now the interface is
always disabled at beginning and (re-)enabled at the last step of
snd_usb_endpoint_configure(), in order to be compliant with the
standard UAC2/3.  For UAC1, the interface is set before the parameter
setups since there seem devices that require it (e.g. Yamaha THR10),
just like how it was done in the previous driver code.

The start/stop are almost same as before, also single-shots.  The URB
callbacks need to be set via snd_usb_endpoint_set_callback() like the
previous code at the trigger phase, too.

Finally, the flag for the re-setup is set at the device suspend
through the full EP list, instead of PCM trigger.  This catches the
overlooked cases where the PCM hasn't been running yet but the device
needs the full setup after resume.

Takashi Iwai 96e221f379 ALSA: usb-audio: Set callbacks via snd_usb_endpoint_set_callback()
The prepare_data_urb and retire_data_urb fields of the endpoint object
are set dynamically at PCM trigger start/stop.  Those are evaluated in
the endpoint handler, but there can be a race, especially if two
different PCM substreams are handling the same endpoint for the
implicit feedback case.  Also, the data_subs field of the endpoint is
set and accessed dynamically, too, which has the same risk.

As a slight improvement for the concurrency, this patch introduces the
function to set the callbacks and the data in a shot with the memory
barrier.  In the reader side, it's also fetched with the memory
barrier.

There is still a room of race if prepare and retire callbacks are set
during executing the URB completion.  But such an inconsistency may
happen only for the implicit fb source, i.e. it's only about the
capture stream.  And luckily, the capture stream never sets the
prepare callback, hence the problem doesn't happen practically.

Takashi Iwai 5a6c3e11c9 ALSA: usb-audio: Add hw constraint for implicit fb sync
In the current code, there is no check at the stream open time whether
the endpoint is being already used by others.  In the normal
operations, this shouldn't happen, but in the case of the implicit
feedback mode, it's a common problem with the full duplex operation,
because the capture stream is always opened by the playback stream as
an implicit sync source.

Although we recently introduced the check of such a conflict of
parameters at the PCM hw_params time, it doesn't give any hint at the
hw_params itself and just gives the error.  This isn't quite
comfortable, and it caused problems on many applications.

This patch attempts to make the parameter handling easier by
introducing the strict hw constraint matching with the counterpart
stream that is being used.  That said, when an implicit feedback
playback stream is running before a capture stream is opened, the
capture stream carries the PCM hw-constraint to allow only the same
sample rate, format, periods and period frames as the running playback
stream.  If not opened or there is no conflict of endpoints, the
behavior remains as same as before.

Note that this kind of "weak link" should work for most cases, but
this is no concrete solution; e.g. if an application changes the hw
params multiple times while another stream is opened, this would lead
to inconsistencies.

they couldn't be probed properly because the assumption the driver

endpoints assigned to the next altsetting in the same interface.

the implicit fb stream is found in the next interface number.

but use the standard bool to success/failur, which is more intuitive
in this particular case.

Takashi Iwai 93db51d06b ALSA: usb-audio: Check valid altsetting at parsing rates for UAC2/3
The current driver code assumes blindly that all found sample rates for
the same endpoint from the UAC2 and UAC3 descriptors can be used no
matter which altsetting, but actually this was wrong: some devices
accept only limited sample rates in each altsetting.  For determining
which altsetting supports which rate, we need to verify each sample rate
and check the validity via UAC2_AS_VAL_ALT_SETTINGS.  This control
reports back the available altsettings as a bitmap.

This patch implements the missing piece above, the verification and
reconstructs the sample rate tables based on the result.

An open question is how to deal with the altsettings that ended up
with no valid sample rates after verification.  At least, there is a
device that showed this problem although the sample rates did work in
the later usage (see bug link).  For now, we accept such an altset as
is, assuming that it's a firmware bug.

Takashi Iwai 4974b79509 ALSA: usb-audio: Don't call usb_set_interface() at trigger callback
The PCM trigger callback is atomic, hence we must not call a function
like usb_set_interface() there.  Calling it from there would lead to a
kernel Oops.

Fix it by moving the usb_set_interface() call to set_sync_endpoint().

Also, apply the snd_usb_set_interface_quirk() for consistency, too.

Takashi Iwai bc4e94aa8e ALSA: usb-audio: Handle discrete rates properly in hw constraints
In the current code, when the device provides the discrete sample rate
tables with unusual sample rates, the driver tries to gather the whole
values from the audioformat entries and create a hw-constraint rule to
restrict with this single rate list.  This is rather inefficient and
may overlook the rates that are associated only with the certain
audioformat entries.

This patch improves the hw constraint setup by rewriting the existing
hw_rule_rate().  The discrete sample rates (identified by rate_table
and nr_rates of format entry) are checked in the existing
hw_rule_rate() instead of extra rules; in the case of discrete rates,
the function compares with each rate table entry and calculates the
min/max values from there.  For the contiguous rates, the behavior
doesn't change.

Along with it, snd_usb_pcm_check_knot() and snb_usb_substream
rate_list field become superfluous, thus those are dropped.

Keith Winstein f15cfca818 ALSA: usb-audio: Add implicit feedback quirk for Zoom UAC-2
The Zoom UAC-2 USB audio interface provides an async playback endpoint
("1 OUT (ASYNC)") and capture endpoint ("2 IN (ASYNC)"), both with
2-channel S32_LE in 44.1, 48, 88.2, 96, 176.4, or 192
kilosamples/s. The device provides explicit feedback to adjust the
host's playback rate, but the feedback appears unstable and biased
relative to the device's capture rate.

"alsaloop -t 1000" experiences playback underruns and tries to
resample the captured audio to match the varying playback
rate. Forcing the kernel to use implicit feedback appears to
produce more stable results. This causes the host to transmit one
playback sample for each capture sample received. (Zoom North America
has been notified of this change.)

This reverts commit 34dedd2a83.

According to Realtek, volume FU works for line-in.

I can confirm volume control works after device firmware is updated.

The commit 51ab5d77dc ("ALSA: usb-audio: Properly match with audio

pair and bInterface fields to match with all those with a new macro
USB_AUDIO_CLASS().  However, it turned out that those are false
conversions; all those (but the unknown KeithMcMillen device) are
actually with vendor-specific interface class, hence the conversions
broke the matching.

This patch corrects those entries to the right one,
USB_DEVICE_VENDOR_SPEC() (and USB_DEVICE() for KeithMcMillen to be
sure), and drop the unused USB_AUDIO_CLASS macro again.

There are a few entries in the quirk table that set the device ID with

Takashi Iwai 5436f59bc5 ALSA: usb-audio: Move device rename and profile quirks to an internal table
So far we've added the devices that need vendor/product string renames
or the profile setup into the standard quirk table in quirks-table.h.
This table is imported into the primary USB audio device entry, hence
it's all exported for the probing so that udev and co can take a look
at it.  OTOH, for renaming or profile setup, we don't need to expose
those explicit entries because the probe itself follows the standard
way.  That said, we're exposing unnecessarily too many entries.

This patch moves such internal quirk entries into the own table, and
reduces the exported device table size.  Along with the moving items,
re-arrange the entries in the proper order.

Kai-Heng Feng 34dedd2a83 ALSA: usb-audio: Disable Lenovo P620 Rear line-in volume control
The USB device (0x17aa:0x1046) that support Lenovo P620 rear panel
line-in claim to support volume control, but it doens't seem to have an
AMP, so when line-in volume lowers below 80, nothing gets recorded
anymore.

Disable the volume control to workaround the issue.

Hector Martin 1b7ecc241a ALSA: usb-audio: work around streaming quirk for MacroSilicon MS2109
Further investigation of the L-R swap problem on the MS2109 reveals that
the problem isn't that the channels are swapped, but rather that they
are swapped and also out of phase by one sample. In other words, the
issue is actually that the very first frame that comes from the hardware
is a half-frame containing only the right channel, and after that
everything becomes offset.

So introduce a new quirk field to drop the very first 2 bytes that come
in after the format is configured and a capture stream starts. This puts
the channels in phase and in the correct order.

Linus Torvalds 3f9df56480 sound updates for 5.9
This became wide and scattered updates all over the sound tree as
 diffstat shows: lots of (still ongoing) refactoring works in ASoC,
 fixes and cleanups caught by static analysis, inclusive term
 conversions as well as lots of new drivers.  Below are highlights:
 
 ASoC core:
 * API cleanups and conversions to the unified mute_stream() call
 * Simplify I/O helper functions
 * Use helper macros to retrieve RTD from substreams
 
 ASoC drivers:
 * Lots of fixes and cleanups in Intel ASoC drivers
 * Lots of new stuff: Freescale MQS and i.MX6sx, Intel KeemBay I2S,
   Maxim MAX98360A and MAX98373 SoundWire, various Mediatek boards,
   nVidia Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries
   boards, TI J721e EVM
 
 ALSA core:
 * Minor code refacotring for SG-buffer handling
 
 HD-audio:
 * Generalization of mute-LED handling with LED classdev
 * Intel silent stream support for HDMI
 * Device-specific fixes: CA0132, Loongson-3
 
 Others:
 * Usual USB- and HD-audio quirks for various devices
 * Fixes for echoaudio DMA position handling
 * Various documents and trivial fixes for sparse warnings
 * Conversion to adapt inclusive terms
