I have an AUVIO 24 Soundbox, Model SBX24210. The User's Guide that comes with the unit is too minimal and doesn't help me connect the unit properly. I have a 32" flat-screen TV, DVD player, satellite DIrecTV service, and a bit surge protector for electronics. After hooking up everything as I THOUGHT I should, the sound is still coming from the TV and not the soundbox. What am I doing wrong?
