Jesper Juhl 233d84c46c ALSA: Xonar, CS43xx: Don't overrun static array
'cs4398_regs' in 'struct xonar_cs43xx' is an array of 'u8' with a size of
8. So, this code in sound/pci/oxygen/xonar_cs43xx.c::dump_d1_registers()

    		for (i = 2; i <= 8; ++i)
	  			snd_iprintf(buffer, " %02x", data->cs4398_regs[i]);

will overrun the array when 'i == 8'.

I guess that what's needed to fix it is the trivial patch below, but I
must admit that I have no idea about this code, so I may very well be
wrong. Additionally, I have no way to actually test this, so all I know is
that the below compiles. Someone who actually knows this code should take
a look before anything is comitted - consider the below (not much more
than) a bug report.

Clemens Ladisch ce2c492090 ALSA: virtuoso: reduce MCLK in double rate modes
For the CSxxxx and AKxxxx DAC/ADC chips, the MCLK factor in double rate
modes (64-96 kHz) can be reduced to 128x without reducing sound quality.

Clemens Ladisch 5b8bf2a54f ALSA: oxygen: simplify model-specific MCLK handling
Replace the get_i2s_mclk callback with tables of MCLK values.  This
simplifies the MCLK-handling code in both the framework and the model-
specific drivers.

For cards like the Xonar HDAV1.3, differentiate between the number of

Clemens Ladisch e96f38f732 ALSA: virtuoso: fix front panel routing for D1/DX/ST(X)
The "Front Panel" switch on the Xonar D1/DX actually switches only the
output direction, so mark it appropriately.

The front panel microphone is controlled by the FMIC2MIC bit of the
CM9780.  It was unconditionally enabled on the D1/DX and never set on
the ST(X); add a control for it.  Selecting the front panel microphone
as source does not actually disable the microphone jack, but this is
bug-compatible with the Windows driver, and users rely on it.

Clemens Ladisch b6ca8ab399 ALSA: oxygen: handle CD input configuration with a flag
There are more models without a CD input than with one, so handle this
explicitly with a device_config flag to avoid having to define a control
filter callback to filter it out.

Commit 65c3ac885c in 2.6.33 accidentally
left out the initialization of the AC97 codec FMIC2MIC bit, which broke
recording from the front panel microphone.
