I've got my computer hooked up to my Onkyo TX-NR3007 via an HDMI cable coming out of my video card and for the most part it works perfectly with my 7.1 sound setup and my HDTV. However, when I'm using the PC and I switch from working in the front room to working in the bedroom it causes a problem on the PC where it will stop playing audio and lock out the HDMI so it is disabled and can't be re-enabled. The video is fine, but no matter what I try I can't get it to output audio over the HDMI again without restarting the PC. I don't have any idea how to fix the problem (not sure it can be fixed), but the video will always work so I figured I could just connect the audio separately and avoid the whole issue. My motherboard has outputs for coaxial, optical, and multi-channel RCA so I'm wondering which of those will give me the best sound working in concert with my HDMI cable. Can any of those carry the same quality signal that HDMI does? Thanks in advance!
