Problem outputting 5.1 Surround Sound via TV to a Home Cinema System (Override sound supported formats?)

Hi, I am trying to output 5.1 sound to my Home Cinema system via my TV through an optical digital out. So the video card (an Asus EAH5450) is capable of up to 7.1 output, is connected via HDMI to my TV (an LG 47LH5000) which then outputs sound via an optical digital out to my 5.1 Home Cinema system (an LG HB965TZ). I have an xbox360 connected via HDMI to the TV and the 5.1 sound comes through perfectly to the correct speakers.

The problem I think is that the computer is detecting that it is connected to the TV which tells the PC it has 2 speakers, so the Windows 7 sound configuration menu just displays stereo and dolby digital.

Is there a way to override the automatic detection of what the supported formats are and force the card to output 5.1 sound as I know it is capable of?
