The only inputs are the RCA Red/White/Yellow inputs for video and audio.

My motherboard has stereo connectors for a center/woofer, back surround, 
side surround, line in, front out, and a mic.

If I want to connect this to my tv over a single stereo channel where 
would I plug into? The center& woofer?

Unfortunately I don't have a receiver but a home theater system that 
doesn't have much for inputs (RCA red/white/yellow only).
