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.

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,
I will try to downgrade 8.2-RELEASE and then update the kernel code to
more specific version to see where the regression happens.
How can I try this step by step ? Should I try to svn / cvs day per day?
Cheers,
