Dual monitor HDTV audio troubles

Britface · 10-11-2009, 06:10 PM

For a while I've been using an HDTV as my sole monitor, connected via HDMI. Last night I tried to switch to dual with a regular PC monitor conncted via AVI (with a DVI adapter at the PC), but as soon as I switched the monitor setting to dual, the audio gave out. I've been using the TV speakers for my audio (the default is set to "Realtek HDMI Output"), but as soon as I switch to dual, I can't get anything to make a sound.

I've used a dual setup before, with two regular PC monitors (though it was with the same HDMI cable and AVI/DVI adapter), but in that instance I was using separate speakers. So apparently the problem is that it won't let me use the TV speakers when another monitor is involved, I just have no idea how to fix it without setting up separate speakers.

Is there a way to get this working without any extra hardware? Thanks in advance for any help.

What is an "AVI" cable? There are three connection types available (that I'm aware of): 1) VGA ( http://en.wikipedia.org/wiki/Video_Graphics_Array )
2) DVI ( http://en.wikipedia.org/wiki/Digital_Visual_Interface )
3) HDMI ( http://en.wikipedia.org/wiki/HDMI )

Try updating the video drivers. My would be there is a limitation within the video drivers to disable HDMI audio when using multiple monitors. It may be as simple as updating the drivers or just enabling the audio again. Are you using nVidia or ATI drivers?
