DisplayPort for audio only?
So I'm trying to get 5.1 sound from my PC to my my sound bar. However, I keep having a bunch of issues:
1. Using my TV as a pass through works except no surround sound as the computer doesn't "see" the sound bar.
2. Using the optical out on the motherboard also doesn't provide 5.1.
3. Using an HDMI port for the TV and a DisplayPort to HDMI via my GPU to the sound bar gives 5.1 but the PC thinks the sound bar is a monitor and restricts the TV to 1080/60hz.
I've searched for a bit and while I've seen people with the same problem, no solution is ever offered.
