Advanced Linux Sound Architecture - Driver
==========================================
Configuration guide
Kernel Configuration
====================
To enable ALSA support you need at least to build the kernel with
primary sound card support (CONFIG_SOUND). Since ALSA can emulate OSS,
you don't have to choose any of the OSS modules.
Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and
PCM supports if you want to run OSS applications with ALSA.
If you want to support the WaveTable functionality on cards such as
SB Live! then you need to enable "Sequencer support"
(CONFIG_SND_SEQUENCER).
To make ALSA debug messages more verbose, enable the "Verbose printk"
and "Debug" options. To check for memory leaks, turn on "Debug memory"
too. "Debug detection" will add checks for the detection of cards.
Please note that all the ALSA ISA drivers support the Linux isapnp API
(if the card supports ISA PnP). You don't need to configure the cards
using isapnptools.
Creating ALSA devices
=====================
This depends on your distribution, but normally you use the /dev/MAKEDEV
script to create the necessary device nodes. On some systems you use a
script named 'snddevices'.
Module parameters
=================
The user can load modules with options. If the module supports more than
one card and you have more than one card of the same type then you can
specify multiple values for the option separated by commas.
Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed.
Module snd
----------
The core ALSA module. It is used by all ALSA card drivers.
It takes the following options which have global effects.
major - major number for sound driver
- Default: 116
cards_limit
- limiting card index for auto-loading (1-8)
- Default: 1
- For auto-loading more than one card, specify this
option together with snd-card-X aliases.
Module snd-pcm-oss
------------------
The PCM OSS emulation module.
This module takes options which change the mapping of devices.
dsp_map - PCM device number maps assigned to the 1st OSS device.
- Default: 0
adsp_map - PCM device number maps assigned to the 2st OSS device.
- Default: 1
nonblock_open
- Don't block opening busy PCM devices. Default: 1
For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of
the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped
to PCM #0 of the card #0.
For changing the second or later card, specify the option with
commas, such like "dsp_map=0,1".
nonblock_open option is used to change the behavior of the PCM
regarding opening the device. When this option is non-zero,
opening a busy OSS PCM device won't be blocked but return
immediately with EAGAIN (just like O_NONBLOCK flag).
Module snd-rawmidi
------------------
This module takes options which change the mapping of devices.
similar to those of the snd-pcm-oss module.
midi_map - MIDI device number maps assigned to the 1st OSS device.
- Default: 0
amidi_map - MIDI device number maps assigned to the 2st OSS device.
- Default: 1
Common parameters for top sound card modules
--------------------------------------------
Each of top level sound card module takes the following options.
index - index (slot #) of sound card
- Values: 0 through 31 or negative
- If nonnegative, assign that index number
- if negative, interpret as a bitmask of permissible
indices; the first free permitted index is assigned
- Default: -1
id - card ID (identifier or name)
- Can be up to 15 characters long
- Default: the card type
- A directory by this name is created under /proc/asound/
containing information about the card
- This ID can be used instead of the index number in
identifying the card
enable - enable card
- Default: enabled, for PCI and ISA PnP cards
Module snd-adlib
----------------
Module for AdLib FM cards.
port - port # for OPL chip
This module supports multiple cards. It does not support autoprobe, so
the port must be specified. For actual AdLib FM cards it will be 0x388.
Note that this card does not have PCM support and no mixer; only FM
synthesis.
Make sure you have "sbiload" from the alsa-tools package available and,
after loading the module, find out the assigned ALSA sequencer port
number through "sbiload -l". Example output:
Port Client name Port name
64:0 OPL2 FM synth OPL2 FM Port
Load the std.sb and drums.sb patches also supplied by sbiload:
sbiload -p 64:0 std.sb drums.sb
If you use this driver to drive an OPL3, you can use std.o3 and drums.o3
instead. To have the card produce sound, use aplaymidi from alsa-utils:
aplaymidi -p 64:0 foo.mid

single_cmd - Use single immediate commands to communicate with
codecs (for debugging only)
enable_msi - Enable Message Signaled Interrupt (MSI) (default = off)
This module supports one card and autoprobe.
Each codec may have a model table for different configurations.
If your machine isn't listed there, the default (usually minimal)
configuration is set up. You can pass "model=<name>" option to
specify a certain model in such a case. There are different
models depending on the codec chip.

The model name "genric" is treated as a special case. When this
model is given, the driver uses the generic codec parser without
"codec-patch". It's sometimes good for testing and debugging.
If the default configuration doesn't work and one of the above
matches with your device, report it together with the PCI
subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
ML (see the section "Links and Addresses").
Note 2: If you get click noises on output, try the module option
position_fix=1 or 2. position_fix=1 will use the SD_LPIB
register value without FIFO size correction as the current
DMA pointer. position_fix=2 will make the driver to use
the position buffer instead of reading SD_LPIB register.
(Usually SD_LPLIB register is more accurate than the
position buffer.)
NB: If you get many "azx_get_response timeout" messages at
loading, it's likely a problem of interrupts (e.g. ACPI irq
routing). Try to boot with options like "pci=noacpi". Also, you
can try "single_cmd=1" module option. This will switch the
communication method between HDA controller and codecs to the
single immediate commands instead of CORB/RIRB. Basically, the
single command mode is provided only for BIOS, and you won't get
unsolicited events, too. But, at least, this works independently
from the irq. Remember this is a last resort, and should be
avoided as much as possible...
MORE NOTES ON "azx_get_response timeout" PROBLEMS:
On some hardwares, you may need to add a proper probe_mask option
to avoid the "azx_get_response timeout" problem above, instead.
This occurs when the access to non-existing or non-working codec slot
(likely a modem one) causes a stall of the communication via HD-audio
bus. You can see which codec slots are probed by enabling
CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
proc files. Then limit the slots to probe by probe_mask option.
For example, probe_mask=1 means to probe only the first slot, and
probe_mask=4 means only the third slot.
The power-management is supported.
Module snd-hdsp
---------------
Module for RME Hammerfall DSP audio interface(s)
This module supports multiple cards.
Note: The firmware data can be automatically loaded via hotplug
when CONFIG_FW_LOADER is set. Otherwise, you need to load
the firmware via hdsploader utility included in alsa-tools
package.
The firmware data is found in alsa-firmware package.
Note: snd-page-alloc module does the job which snd-hammerfall-mem
module did formerly. It will allocate the buffers in advance
when any HDSP cards are found. To make the buffer
allocation sure, load snd-page-alloc module in the early
stage of boot sequence. See "Early Buffer Allocation"
section.

playback_bufsize - max playback frame size in kB (4-128kB)
capture_bufsize - max capture frame size in kB (4-128kB)
force_ac97 - 0 or 1 (disabled by default)
buffer_top - specify buffer top address
use_cache - 0 or 1 (disabled by default)
vaio_hack - alias buffer_top=0x25a800
reset_workaround - enable AC97 RESET workaround for some laptops
reset_workaround2 - enable extended AC97 RESET workaround for some
other laptops
This module supports one chip and autoprobe.
The power-management is supported.
Note: on some notebooks the buffer address cannot be detected
automatically, or causes hang-up during initialization.
In such a case, specify the buffer top address explicitly via
the buffer_top option.
For example,
Sony F250: buffer_top=0x25a800
Sony F270: buffer_top=0x272800
The driver supports only ac97 codec. It's possible to force
to initialize/use ac97 although it's not detected. In such a
case, use force_ac97=1 option - but *NO* guarantee whether it
works!
Note: The NM256 chip can be linked internally with non-AC97
codecs. This driver supports only the AC97 codec, and won't work
with machines with other (most likely CS423x or OPL3SAx) chips,
even though the device is detected in lspci. In such a case, try
other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
but some doesn't have ISA PnP. You'll need to specify isapnp=0
and proper hardware parameters in the case without ISA PnP.
Note: some laptops need a workaround for AC97 RESET. For the
known hardware like Dell Latitude LS and Sony PCG-F305, this
workaround is enabled automatically. For other laptops with a
hard freeze, you can try reset_workaround=1 option.
Note: Dell Latitude CSx laptops have another problem regarding
AC97 RESET. On these laptops, reset_workaround2 option is
turned on as default. This option is worth to try if the
previous reset_workaround option doesn't help.
Note: This driver is really crappy. It's a porting from the
OSS driver, which is a result of black-magic reverse engineering.
The detection of codec will fail if the driver is loaded *after*
X-server as described above. You might be able to force to load
the module, but it may result in hang-up. Hence, make sure that
you load this module *before* X if you encounter this kind of
problem.

Module for AC'97 motherboards based on VIA 82C686A/686B, 8233,
8233A, 8233C, 8235, 8237 (south) bridge.
mpu_port - 0x300,0x310,0x320,0x330, otherwise obtain BIOS setup
[VIA686A/686B only]
joystick - Enable joystick (default off) [VIA686A/686B only]
ac97_clock - AC'97 codec clock base (default 48000Hz)
dxs_support - support DXS channels,
0 = auto (default), 1 = enable, 2 = disable,
3 = 48k only, 4 = no VRA, 5 = enable any sample
rate and different sample rates on different
channels
[VIA8233/C, 8235, 8237 only]
ac97_quirk - AC'97 workaround for strange hardware
See "AC97 Quirk Option" section below.
This module supports one chip and autoprobe.
Note: on some SMP motherboards like MSI 694D the interrupts might
not be generated properly. In such a case, please try to
set the SMP (or MPS) version on BIOS to 1.1 instead of
default value 1.4. Then the interrupt number will be
assigned under 15. You might also upgrade your BIOS.
Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
channels as the first PCM. On these channels, up to 4
streams can be played at the same time, and the controller
can perform sample rate conversion with separate rates for
each channel.
As default (dxs_support = 0), 48k fixed rate is chosen
except for the known devices since the output is often
noisy except for 48k on some mother boards due to the
bug of BIOS.
Please try once dxs_support=5 and if it works on other
sample rates (e.g. 44.1kHz of mp3 playback), please let us
know the PCI subsystem vendor/device id's (output of
"lspci -nv").
If dxs_support=5 does not work, try dxs_support=4; if it
doesn't work too, try dxs_support=1. (dxs_support=1 is
usually for old motherboards. The correct implemented
board should work with 4 or 5.) If it still doesn't
work and the default setting is ok, dxs_support=3 is the
right choice. If the default setting doesn't work at all,
try dxs_support=2 to disable the DXS channels.
In any cases, please let us know the result and the
subsystem vendor/device ids. See "Links and Addresses"
below.
Note: for the MPU401 on VIA823x, use snd-mpu401 driver
additionally. The mpu_port option is for VIA686 chips only.
The power-management is supported.
Module snd-via82xx-modem
------------------------
Module for VIA82xx AC97 modem
ac97_clock - AC'97 codec clock base (default 48000Hz)

This module supports multiple cards.
Module snd-vx222
----------------
Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards.
mic - Enable Microphone on V222 Mic (NYI)
ibl - Capture IBL size. (default = 0, minimum size)
This module supports multiple cards.
When the driver is compiled as a module and the hotplug firmware
is supported, the firmware data is loaded via hotplug automatically.
Install the necessary firmware files in alsa-firmware package.
When no hotplug fw loader is available, you need to load the
firmware via vxloader utility in alsa-tools package. To invoke
vxloader automatically, add the following to /etc/modprobe.conf
install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
(for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
/etc/modules.conf, instead.)
IBL size defines the interrupts period for PCM. The smaller size
gives smaller latency but leads to more CPU consumption, too.
The size is usually aligned to 126. As default (=0), the smallest
size is chosen. The possible IBL values can be found in
/proc/asound/cardX/vx-status proc file.
The power-management is supported.
Module snd-vxpocket
-------------------
Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
ibl - Capture IBL size. (default = 0, minimum size)
This module supports multiple cards. The module is compiled only when
PCMCIA is supported on kernel.
With the older 2.6.x kernel, to activate the driver via the card
manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
longer require a config file.
When the driver is compiled as a module and the hotplug firmware
is supported, the firmware data is loaded via hotplug automatically.
Install the necessary firmware files in alsa-firmware package.
When no hotplug fw loader is available, you need to load the
firmware via vxloader utility in alsa-tools package.
About capture IBL, see the description of snd-vx222 module.
Note: snd-vxp440 driver is merged to snd-vxpocket driver since
ALSA 1.0.10.
The power-management is supported.

The power-management is supported.
Module snd-pdaudiocf
--------------------
Module for Sound Core PDAudioCF sound card.
The power-management is supported.
AC97 Quirk Option
=================
The ac97_quirk option is used to enable/override the workaround for
specific devices on drivers for on-board AC'97 controllers like
snd-intel8x0. Some hardware have swapped output pins between Master
and Headphone, or Surround (thanks to confusion of AC'97
specifications from version to version :-)
The driver provides the auto-detection of known problematic devices,
but some might be unknown or wrongly detected. In such a case, pass
the proper value with this option.
The following strings are accepted:
- default Don't override the default setting
- none Disable the quirk
- hp_only Bind Master and Headphone controls as a single control
- swap_hp Swap headphone and master controls
- swap_surround Swap master and surround controls
- ad_sharing For AD1985, turn on OMS bit and use headphone
- alc_jack For ALC65x, turn on the jack sense mode
- inv_eapd Inverted EAPD implementation
- mute_led Bind EAPD bit for turning on/off mute LED
For backward compatibility, the corresponding integer value -1, 0,
... are accepted, too.
For example, if "Master" volume control has no effect on your device
but only "Headphone" does, pass ac97_quirk=hp_only module option.
Configuring Non-ISAPNP Cards
============================
When the kernel is configured with ISA-PnP support, the modules
supporting the isapnp cards will have module options "isapnp".
If this option is set, *only* the ISA-PnP devices will be probed.
For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
together with the proper i/o and irq configuration.
When the kernel is configured without ISA-PnP support, isapnp option
will be not built in.
Module Autoloading Support
==========================
The ALSA drivers can be loaded automatically on demand by defining
module aliases. The string 'snd-card-%1' is requested for ALSA native
devices where %i is sound card number from zero to seven.
To auto-load an ALSA driver for OSS services, define the string
'sound-slot-%i' where %i means the slot number for OSS, which
corresponds to the card index of ALSA. Usually, define this
as the same card module.
An example configuration for a single emu10k1 card is like below:
----- /etc/modprobe.conf
alias snd-card-0 snd-emu10k1
alias sound-slot-0 snd-emu10k1
----- /etc/modprobe.conf
The available number of auto-loaded sound cards depends on the module
option "cards_limit" of snd module. As default it's set to 1.
To enable the auto-loading of multiple cards, specify the number of
sound cards in that option.
When multiple cards are available, it'd better to specify the index
number for each card via module option, too, so that the order of
cards is kept consistent.
An example configuration for two sound cards is like below:
----- /etc/modprobe.conf
# ALSA portion
options snd cards_limit=2
alias snd-card-0 snd-interwave
alias snd-card-1 snd-ens1371
options snd-interwave index=0
options snd-ens1371 index=1
# OSS/Free portion
alias sound-slot-0 snd-interwave
alias sound-slot-1 snd-ens1371
----- /etc/modprobe.conf
In this example, the interwave card is always loaded as the first card
(index 0) and ens1371 as the second (index 1).
ALSA PCM devices to OSS devices mapping
=======================================
/dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
/dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
/dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
/dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
/dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
/dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
/dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
/dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
/dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
sound card number and second means device number. The ALSA devices
have either 'c' or 'p' suffix indicating the direction, capture and
playback, respectively.
Please note that the device mapping above may be varied via the module
options of snd-pcm-oss module.
Proc interfaces (/proc/asound)
==============================
/proc/asound/card#/pcm#[cp]/oss
-------------------------------
String "erase" - erase all additional informations about OSS applications
String "<app_name> <fragments> <fragment_size> [<options>]"
<app_name> - name of application with (higher priority) or without path
<fragments> - number of fragments or zero if auto
<fragment_size> - size of fragment in bytes or zero if auto
<options> - optional parameters
- disable the application tries to open a pcm device for
this channel but does not want to use it.
(Cause a bug or mmap needs)
It's good for Quake etc...
- direct don't use plugins
- block force block mode (rvplayer)
- non-block force non-block mode
- whole-frag write only whole fragments (optimization affecting
playback only)
- no-silence do not fill silence ahead to avoid clicks
- buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
instead of filled blocks
Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
Early Buffer Allocation
=======================
Some drivers (e.g. hdsp) require the large contiguous buffers, and
sometimes it's too late to find such spaces when the driver module is
actually loaded due to memory fragmentation. You can pre-allocate the
PCM buffers by loading snd-page-alloc module and write commands to its
proc file in prior, for example, in the early boot stage like
/etc/init.d/*.local scripts.
Reading the proc file /proc/drivers/snd-page-alloc shows the current
usage of page allocation. In writing, you can send the following
commands to the snd-page-alloc driver:
- add VENDOR DEVICE MASK SIZE BUFFERS
VENDOR and DEVICE are PCI vendor and device IDs. They take
integer numbers (0x prefix is needed for the hex).
MASK is the PCI DMA mask. Pass 0 if not restricted.
SIZE is the size of each buffer to allocate. You can pass
k and m suffix for KB and MB. The max number is 16MB.
BUFFERS is the number of buffers to allocate. It must be greater
than 0. The max number is 4.
- erase
This will erase the all pre-allocated buffers which are not in
use.
