I'm really at a dead end with HDMI audio. Audio works fine until
X starts, then I get the following message in dmesg:
HDMI hot plug event: Presence_Detect=0 ELD_Valid=1
If I stop X, then I get
HDMI hot plug event: Presence_Detect=1 ELD_Valid=1
and sound continues again.
This is with a G45 chipset.
Looking at the xf86-video-intel source, I see stuff like this:
sdvox |= SDVO_AUDIO_ENABLE;
Someone else suggested that the video driver is taking
away the audio from the alsa driver, so anywhere that
something in the video driver does something like the
above, I commented it out. Admittedly that sounds a bit
desperate and it didn't work anyway...
Anyone know how I can either pipe audio into the
intel hdmi video driver's audio, or disable it in
favour of the alsa hdmi driver?
