So I've been using a Sony DAV-TZ130 DVD home theater system for a few years in our basement. I had it hooked up to an xbox 360 E and was getting 5.1 surround perfectly for gaming and movies and such. I recently got a mid level PC and wanted to hook it up, but all I can get is stereo with the RF and LF speakers. I was hoping I could get surround sound so if anyone can help anything is appreciated. Thank you!
