[Pkg-alsa-devel] Bug#515340: alsa-base_1.0.17.dfsg-4 problem

[Tong Sun]

Package: alsa-base
Version: 1.0.17.dfsg-4
Severity: normal

My recent upgrade caused my sound card not working any more. Checking back
at my packages version log, the only related upgrade is that
alsa-base_1.0.17.dfsg-2 is upgraded to alsa-base_1.0.17.dfsg-4. 
The rest are still the same:

  alsa-oss_1.0.15-1
  alsa-utils_1.0.16-2

Yet, now I've got:

  % alsaconf 
  Loading driver...
  Setting default volumes...
  amixer: Mixer attach default error: No such file or directory
  Saving the mixer setup used for this in /var/lib/alsa/asound.state.

  Now ALSA is ready to use.
  For adjustment of volumes. . . 

  $ ls /dev/dsp
  ls: cannot access /dev/dsp: No such file or directory

  $ cat /dev/sndstat 
  Sound Driver:3.8.1a-980706 (ALSA v1.0.16 emulation code)
  Kernel: Linux helios.selfip.org 2.6.26-grml #1 SMP PREEMPT Wed Nov 26 21:41:43 UTC 2008 i686
  Config options: 0

  Installed drivers: 
  Type 10: ALSA emulation

  Card config: 
  VIA 8237 with AD1980 at 0xc800, irq 22

  Audio devices: NOT ENABLED IN CONFIG

  Synth devices: NOT ENABLED IN CONFIG

  Midi devices: NOT ENABLED IN CONFIG

  Timers:
  31: system timer

  Mixers: NOT ENABLED IN CONFIG

Trying the remove and re-install approach,

  % dpkg --force-depends --purge alsa-base alsa-oss alsa-utils libasound2 libesd-alsa0 linux-sound-base
  % aptitude --purge-unused install alsa-base alsa-oss alsa-utils libasound2 libesd-alsa0 linux-sound-base

Results the same "amixer: Mixer attach default error" after alsaconf.

Again, everything was working fine with alsa-base_1.0.17.dfsg-2. 
Detailed info regarding my sound card (and software) is posted at

Thanks
