ALSA: hda - Fix invalid D3 of headphone DAC on VT202x codecs
commit 6162552b0de6ba80937c3dd53e084967851cd199 upstream. We've got a bug report about the silent output from the headphone on a mobo with VT2021, and spotted out that this was because of the wrong D3 state on the DAC for the headphone output. The bug is triggered by the incomplete check for this DAC in set_widgets_power_state_vt1718S(). It checks only the connectivity of the primary output (0x27) but doesn't consider the path from the headphone pin (0x28). Now this patch fixes the problem by checking both pins for DAC 0x0b. Signed-off-by: Takashi Iwai <tiwai@suse.de> [bwh: Backported to 3.2: keep using snd_hda_codec_write() as update_power_state() is missing] Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
