Bug Description

Binary package hint: linux-source-2.6.22

Sound output with the 2.6.22-10-generic kernel is not working for me. It is working fine with 2.6.22-9. This is on an AMD64 machine (ASUS A8N-VM CSM). With 2.6.22-10 I get this:

# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: HDA Generic [HDA Generic]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

(AFAIK, the HDA Generic indicates that ALSA did not recognize the device.)

Whereas with 2.6.22-9 I get this:

# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: AD198x Analog [AD198x Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 1: AD198x Digital [AD198x Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

The remaining configuration is of course the same, I am just booting with different kernels. I do not see any logging statements in the kernel log that would relate to ALSA with either kernel.

I just installed alsa-source, compiled with the default settings, rebooted and with that sound is working fine. aplay displays the correct devices.

This bug seems generic with almost all HDA mixers.

And, the only output that works is the headphones.

It's a big regression.
