ALSA: hda - Mute headphone pin on suspend on XPS13 9333
Muting the headphone output pin right before the codec suspension prevents pop noises when headphones are plugged in (except for a barely audible click noise). This solution allows to truly save some power when headphones are plugged in unlike the previous solution (033b0a7ca9c: "ALSA: hda - Pop noises fix for XPS13 9333") Signed-off-by: Gabriele Mazzotta <gabriele.mzt@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
