Hello, I don't know if there is a lot of changes in the snd_hda driver in the -STABLE branch but since I upgraded to it sometimes I have sound and sometimes not. The mixer are exactly the same when these event occurs. This happened this morning. After booting I do not have any sound. I rebooted and suddenly I've got sound again... I only tweak snd_hda(4) for a pin sense on the front panel (it has no sound neither) So I added in /boot/devices.hints : hint.hdac.1.cad0.nid27.config="as=1 seq=15" And there's the both dmesg ok.txt when sound is here and not.txt when there isn't as you can see there is no difference related to the hda driver. http://markand.malikania.fr/ok.txt http://markand.malikania.fr/nok.txt I'm guessing something. My laptop has a mute shortcut, if I press it at the BIOS stage I will not have sound neither thus is it possible that my chipset is muted from anything? Cheers, -- David Demelier

How can I try this step by step ? Should I try to svn / cvs day per day? Cheers, -- David Demelier
