[Pkg-alsa-devel] Bug#611533: Bug#611533: Bug#611533: alsa-base: version issue: kernel provides 1.0.21 drivers, alsa is 1.0.23

[Brice Rebsamen]

I removed the module (alsa-module-1.0.23-2.6.35-686)

mplayer -vo none some-sound-file
Sound --> Yes

cvlc some-video-file
no sound
[0xb6f1439c] main audio output error: Potential ALSA version problem
[0xb6f1439c] main audio output error: VLC failed to initialize your
sound output device (if any).
Please update alsa-lib to version 1.0.23-2-g8d80d5f or higher to try
to fix this issue.
[0xb6f1439c] oss audio output error: cannot open audio device (/dev/dsp)

aplay some-wav-file
no sound
ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
aplay: main:654: audio open error: No such file or directory



When I ran alsamixer, the device in the home screen was my USB camera
(it has a microphone).
I unplugged the camera,  restarted my system and did all of the above
test again. This time I had sound for all of them, as well as in X...


So:
1- the bug report is invalid: there is no version issue.
2- It is weird though that things work with the 1.0.23 version, maybe
because I installed it when the camera was installed, or maybe because
it came with fresh configuration files... I'll investigate more.
3- I need to find how to configure alsa so that my sound card is my
default device. Any guidance is appreciated.

Regards
Brice
