Thanks, that's helpful.
As a quirk solution, could you try to pass model=auto option to
snd-hda-intel module?  You may need to adjust the mixer after changing
this, but it should provide the full (even better) functionality.
It'll support also the auto-mic jack switching.

If auto-parser works with this hardware, we don't need to debug the
old code but just switch to the auto-parser statically in the driver.


thanks,
