snd_hda : sometimes sound sometimes not

[David Demelier]

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,
