> 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).
