ALSA: hda - fixup D3 pin and right channel mute on Haswell HDMI audio When graphics initializes the HDMI chip, sometimes this leads to pins going into D3 and right channel being muted. If the audio driver finishes initialization before the graphic driver does, this situation becomes permanent. This is a workaround that checks for this situation and corrects it on playback prepare. It has been verified working on at least one machine.
