I’m thinking my assumption that my receiver requires that both sound and video come from the HDMI. I am looking through the manual and it seems that I can get my sound from a digital input by reconfiguring the receiver. That may be the better path. Then I will be trying to get a Sound Card to work (ASUS Xonar DG), not a video card…
Any fixes for the video card are still welcome. Otherwise, I will be looking for an optical cable to start over…
