Binary package hint: linux-image-2.6.17-10-generic
Edgy installed on a D900t laptop (like Sager 9860, Peutium 4, ALC 880 realtek sound)
Sound simply does not work. When I try to play sound :
aplay /usr/share/sounds/generic.wav
ALSA lib pcm_dmix.c:862:(snd_pcm_dmix_open) unable to open slave
aplay: main:547: audio open error: invalid argument
This bug appeared in Dapper with my laptop, sound was ok before. In dapper I noticed that compiling alsa from source with debug=detect allowed the sound to work, though at each eand of sound, a bunch of debug info appeared in dmeg etc...
Now, I installed edgy, and sound does not work at all, even with a self-compiled with debug option alsa !!! I always get the abovereported result.
I must also mention that surprisingly, alsamixer/amixer seem to work ok, and do not give any suspect results.

Now, I installed edgy, and sound does not work at all, even with a self-compiled alsa with the debug option activated !!! I always get the above reported result.

[workaround and cause]
if you delete the file '/var/lib/alsa/asound.state' and reboot, the alsa driver is properly loaded. then, you can tweak the mixer settings to get sound (for me, i have to enable surround sound).
however, the next time you reboot, the sound goes away again and you have to repeat the process.
thus, i believe the problem lies with the alsa startup script. if the file '/var/lib/alsa/asound.state' exists at boot, alsa tries to load it but gets confused and alsa doesn't properly configure. maybe the file isn't properly formatted; i know it refers to controls that don't exist on my card.

linux: statusexplanation |
The 18 month support period for Edgy Eft 6.10 has reached it's end of life. As a result, we are closing the linux-source-2.6.17 Edgy Eft kernel task. However, can you confirm if this issue still exists in the Hardy Heron 8.04 LTS release or, alternatively the Intrepid Ibex 8.10 Alpha2 which is also scheduled for release today? It will appear at the following when available: http://www.ubuntu.com/testing/intrepid/alpha2 . It contains the the actively developed 2.6.26 Ubuntu kernel. It would be great if you could test this upcoming release via a LiveCD and verify if the issue still exists. If so, please include the appropriate debugging information as outlined at https://wiki.ubuntu.com/DebuggingSoundProblems and set the status of the bug to 'new' and the bug will be reviewed again. Thanks in advance. |
