I have been having a very strange problem with audio for one particular channel on my AT&T Uverse system in my office. I have my Uverse box hooked up to my Pioneer VSX-60 amp via an HDMI cable. When I am watching channel 1777 Time Warner Sports Net, the surround audio is very choppy. If I switch my Uverse box to stereo instead of surround the audio is just fine. I have tried multiple surround modes on my Pioneer amp but any mode still yields choppy audio. I have contacted AT&T but they state that the channel audio is just fine. I have also tried to swap out the Uverse box with one from a different room and it has the same problem. The same channel in my main living room works just fine with the surround. This appears to be a problem with my amp specifically. Not quite sure why just this channel has bad surround audio. Any thoughts or suggestions? Thanks!!!
