[alsa-devel] auto_mute for early patch issue

[Kailang]

Hi Takashi,

I forgot it solved this issue for ALC283 before. It was also chrome OS case.
I cooked attach patch. It will not need to move spec->suppress_auto_mute check line.
Many thanks.

BR,
Kailang

That's the result with your suggested change (moving
spec->supress_auto_mute_mode in check_auto_mute_availability()) ??
