sound (ALC880) does not work in edgy

[Eric]

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.

The 18 month support period for Edgy Eft 6.10 has reached its end of life. As a result, we are closing the linux-source-2.6.17 Edgy Eft kernel task. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
