ALSA: virtuoso: add HDMI enable switch for HDAV1.3
The GPIO bit that enables analog output on the Xonar HDAV1.3 also disables the HDMI audio output, so we better add a switch for it. Hopefully, this is sufficient to make the HDMI output work. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
