Got that. Tried the optical in (for sound), from my TV, but get nothing. Tried a 3.5mm from my phone, and nothing also.
My guess is the old speaker cable I had for the other sound system is a no go. Not sure why?
Edit: Wrong optical input. Working now. Sorta. Some speakers a no go. May have some cable issues.
Second edit: Okay, popped in a Blu ray and they're all working. Sweet.
