Subject: ALSA: hda/via - Fix wrongly cleared pins after suspend on
VT1802
From: Takashi Iwai <[email protected]>
commit 5a6f294e87974e6ec68d7113553ffd975d83bf15 upstream.
VIA driver has a special suspend handling only for VT1802 to reduce
the pop noise. During the transition to the generic parser, the
behavior of snd_hda_set_pin_ctl() was also changed to modify the
cached values, too. And this caused a regression where the pin is
still cleared even after the resume (including the resume from power
save), resulting in the silent output.
The fix is simply to replace snd_hda_set_pin_ctl() with the explicit
call of snd_hda_codec_write() again.
