My graphics card with hdmi output is adament that my receiver/TV can only do 2 channel. However I know this is not the case. I've heard there is a way to override this, can someone point me in the right direction?
Before you go override the EDID, how is your receiver configured and connected? I assume you have an HDMI receiver. In most cases, if you didn't turn off HDMI audio from receiver to TV, your receiver will report 2-ch stereo in its EDID. For most TVs, their HDMI inputs are indeed 2-ch stereo only. Override and force send DD 5.1 will not result anything.
