I installed Ubuntu Feisty on a D900t laptop : it contains a ALC880 audio chipset

eric@gondor:~$ lspci |grep Audio 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03)

When modprobing the modules I get : eric@gondor:~$ sudo modprobe -v snd-hda-intel model=3stack-digout insmod /lib/modules/2.6.20-15-generic/kernel/sound/pci/hda/snd-hda-codec.ko insmod /lib/modules/2.6.20-15-generic/kernel/sound/pci/hda/snd-hda-intel.ko model=3stack-digout

while /var/log/messages says : May 14 14:42:45 gondor kernel: [ 3699.070904] hda_intel: azx_get_response timeout, switching to polling mode...

Feisty dist. is provided with alsa-1.0.13. I get no sound, here are the results of aplay :

asoundconf output : eric@gondor:~$ asoundconf list Names of available sound cards: Intel SAA7134

I tried a lot of workarounds but none worked : boot options (irqpoll, pci=noacpi), single_cmd=1, position_fix=1, several models of hda-intel driver, I tried 1.0.13 and 1.0.14rc4 driver, with debug on...

I must add that I already had this problem with previous distributions of Ubuntu. It worked with an old one (Breezy) then in Dapper and Edgy, it did worked ONLY when I self-compiled the driver with debug option enabled I never understood why. And now with Feisty/alsa 1.0.13/ubuntu kernel 2.6.20, or an ubuntu kernel with self-compiled alsa 1.0.14rc4, it does not work. I cannot have one sound :-(.

Please help me ....
