Hello,

I'm experiencing some troubles with the patches you included in
2.6.10-ac5 about ALSA : the files open and play ok, but no sound is
actually outputed...

I've found that the patch sound/pci/ac97/ac97_patch.c (hereby
attached) is responsible for that (ie when I boot with the full patch 
minus this one, the sound is ok).

Nothing special is printed in dmesg, so I've only attached my lspci 
output and my .config (along with the patch).

Feel free to CC me if more details are needed, for I'm not on the lkml.

Regards,

Jules
