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
