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.
