I was wondering in any one knew anything that might cause my HD Broadcast Audio cuts in and out when going thru my HT system? I have standard tier cable (time warner) and have no cable box or card, just coaxal directly from the wall to the HDTV. I have a toshiba 56" HDTV and I am running optical out to my B&K Ref 50. I have tried different optical cords and determined that it is not the cord, also have determined that it is not the particular input on the ref 50, by trying the cd and dvd input which work fine with their players. When the audio cuts in and out (not constantly but just now and then) the HDTV's audio does not. ( if the tv's volume is up) What I was wondering was if it is the processer or the HDTV? Or maybe just a problem from the broadcast with compression or just processer speed? Any help would be great.
