DVI-D 3D 120HZ, HDMI audio only

[throughstream]

Hi I have two gforce 460 sli set up and a benq xl2410t 3d monitor. To get 120hz 3D I have to use the dvi-d connector. No problem. I then have an AV receiver (not 3d) so I connect the hdmi connector to it for audio. However my computer then thinks I have two displays and I can only get audio if I clone or extend the desktop. I can't clone the desktop as it then reduces the resolution so I have to click extend which means the mouse can go off one side of the screen. Is there any way I can just tell the graphics card to send audio through the hdmi port or do I need to purchase a sound card. I can't use optical as it broke on my motherboard.

Any help would be most appreciated.

Regards

Dave

Why can't you just stick with extend?

I can live with it, it's just annoying when the mouse wonders off the screen. So thought I'd ask. Plus I wasn't sure if it was using up graphics processing power to run two screens.
