From 2509ec623d44320419d44d4060dbedf91b8d192d Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Thu, 2 Dec 2010 11:38:06 +0100 Subject: 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.
