ALSA: hda/realtek - Support low power consumption for ALC256
Remove hp_pin = 0 return. Add the default pin 0x21 as headphone. Supported low power consumption, it must do depop procedure when headset jack was plugged or unplugged. So, alc256_init() and alc256_shutup() must run delay when headset jack was plugged or unplugged. If depop procedure not run with delay, it will have a chance to let power consumption raise high. [ NOTE: this is a quite quite similar change for ALC295 by commit d3ba58bb8959 ("ALSA: hda/realtek - Support low power consumption for ALC295"), but applied to ALC256 codec instead -- tiwai ] Fixes: 8983eb602af5 ("ALSA: hda/realtek - Move to ACT_INIT state") Signed-off-by: Kailang Yang <kailang@realtek.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
