Cat5 to Component w/digital audio adapters are common and not to expensive. but I want to do stereo, 2 chan audio. I found one adapter but it was $350, way more than I want to spend.
Using the 8 wires in the cat5, could I just use 4 for the video (3 for RGB and 1 for common ground) and the other 4 for 2 chan audio? (obviously all preamp level)
I would use a wall plate with 5 rca connectors to connect the cat5 to like these

Would this work?
