I have my HT setup as a 7.2. I noticed that my surr L/R speakers (polk fxi a4) don't always produce sound (when watching TV). I have my receiver set to Dolby Digital + PLIIx Cinema. I switched to DD ex and it functions the same. My surr backs both produce constantly. The test tone works with all speakers, and I do not notice this issue when playing xbox or watching movies. My channel levels are all set properly. I was just wondering why this happens. For example...I am watching NBC sports and hockey is on...the speakers do not produce sound. Then a Wendy's commercial comes on and they do!? Am I missing something? I also have my crossover set properly as well. Thanks for the help!
