With the exception of DISH premiums, for the most part there is a lack of complete 5.1 audio on DISH. And, I suppose this is normal for most shows. However, I would have thought that the Superbowl, perhaps during the musical Half-time event, some sound would radiate from the back speakers. There was none and I turned the back speakers all the way up. Not even low background audience noise. Did anyone with a 5.1+ setup notice any sound from their back speakers?
