Description:
Hi,

I have up-to-dated my PC as I frequently do with the only surprising difference that this time the latest kernel26 package causes my audio subsystem to stop working. By simply going back to the previous version I had (kernel26 2.6.36.1-3) everything gets fixed. I have compared the list of modules loaded with each kernel version and the main difference is that the latest kernel does not load the dm_mod module. Please, have a look to the attached files for more details.

Additional info:
* package version(s)
kernel26 2.6.36.2

* config and/or log files etc.
All the following commands have been issued on kernel26-2.6.36.1-3:
lspci -v --> http://pastebin.com/c13QDXSB
aplay -l --> http://pastebin.com/JrM0Gkb0
aplay -L --> http://pastebin.com/3dE1Dbin

Steps to reproduce:
Just install the package kernel26 2.6.36.2-1
   lsmod-2.6.36.1-3.txt (2.8 KiB)
   lsmod-2.6.36.2-1.txt (2.8 KiB)
This task depends upon

The same problem remains in the version 2.6.36.3-1 So, I'm force to keep using the version 2.6.36.1-3 :-(

The same problem remains with kernel26-2.6.37, BUT, I have found temporary workaround. I have specified my sound card model to the driver in the /etc/modprobe.d/modprobe.conf file:
options snd_hda_intel model=intel-alc889a
#options snd_hda_intel model=6stack-dig
#options snd_hda_intel model=alc883-6stack-dig
#options snd_hda_intel model=targa-8ch-dig

All the above models work and I'm pretty sure the remainder (ALC889 - http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt), ** but 'auto' **, also would.

The only problem it's that when I'm booting my computer it shows the next error ugly trace:

:: Restoring ALSA Levels [BUSY]
Unknown hardware: "HDA-Intel" "Realtek ALC889" "HDA:10ec0889,1458a102,00100004" "0x1458" "0xa102"

/usr/sbin/alsactl: set_control:1255: failed to obtain info for control #19 (No such file or directory)
[FAIL]
I hope it helps someone else!

In the end I got to fully fix it. The model 6stack-dig did the trick. I thought I had tried it before, but somehow it seems I didn't. Now, my sound system is working and no ugly error trace comes up. I have created a brand-new files at /etc/modprobe.conf/alsa.conf which it's attached and left /etc/modprobe.d/modprobe.conf in its original state. If you know a better/cleaner way to pass the model argument to the driver, please, let me know.

Best regards!
