All 6 have boxes around them. The three front speakers all have sound coming out. I can't tell if the sub is working. The two rears have a very light static if you put your ear really close, so they're getting power.

When I try surround mode, I get (3/2).1. If I hit it again, I get "mode unavailable" over and over. Which makes no sense, because earlier I got 5 or 6 choices (with the same movie in the same blue-ray).

Remember: from another device (an Xbox with the Halo speaker test), all six speakers work correctly.
