I have a Sony CT 150 connected to an LG TV and a Comcast DVR cable box via a digital optical cord directly from the TV to the Sony. The sound bar delivers great sound, except that from time to time, the sound "gets stuck" -- replaying the same short sound burst over and over again. If I was watching live TV, I usually have to change channels to get the audio back to normal. If playing a program from the DVR, I usually have to stop the DVR and then change channels. Sometimes I have to change channels on the cable box several times. Anyone run into the same problem? Any solutions?
