@mitu This was the fix, thank you! I think this might have been a remnant of my original setup cause I was having some HDMI issues with a black screen initially.

For some reason this fix broke my audio, but I was able to get that working again after about 30 minutes of tinkering.

Thanks for the assist!

It was easier than I expected! Forced from Audio menu in Retropie. Thanks guys!

I'm having the same issues currently. Did you ever find a fix for this issue of swapping from HDMI to DVI? If I find anything myself, I'll post back.
