You need to right click on the sound in the control panel, select the HDMI icon and go to properties and make HDMI the default sound path. You need to reverse this to get sound back to the PC.

Thank you for the response, but I have already done this.

I am only having problems getting Dolby through the the HDMI cable. When playing a DVD on my computer through my receiver, the receiver displays Multi Chnl. When I connect via the optical SPDIF cable on the back of the XPS 8500, my receiver displays Dolby when playing the same source.

I am wondering if it is possible to get Dolby via the HDMI output on the GT 640.

I don't know about the GT 640, but the AMD 6450-based cards support the full HD 7.1.
