Hey everyone, just one question. I have a samsung 52" lcd(LN52a650a), Yamaha a/v receiver(RX-V565), PS3, Cable box, and Bose Acoustimass 10 system. Everything works fine. But when my surround sound system is not in use i'd like to be able to use the speakers from my TV to watch regular tv. My cable box has an optical audio out. as does my tv..can i go that way to get audio from my tv speakers. Any help would be greatly appreciated.
