Hi, I feel stupid. I have a surround sound system - Yamaha 795 receiver. I recently moved down the road and now my center channel doesn't work (speaker is fine). When i checked (using test signal) with the Yamaha to set up the room, i don't hear the test tone from it. Now in the Set Menu the center channel is set to NONE but if i set it to SML or LRG nothing happens except when i watch a movie the peoples voices are too low but still no center audio (when watching Dolby Dig DVD). Everything looks hooked up right. The remote and directions are not very user friendly. Help!
