hi Guys I have recently been experiencing a problem with my audio when I playback Dvds. this is the basic layout: I play the DVD on a sony playstation 2 and the audio is transmitted to my Yamaha receiver (6.1 channel, I forget the model) via an optical cable. The problem occurs intermittently during playback. I will be watching the show and the audio will partially cut out. I will be able to hear the background audio clearly but the speech becomes difficult to hear. this does not occur when I remove the optical cable and playback the audio through the amp through the RCA connection to the receiver, however I obviously prefer my movies in surround as opposed to stereo. I also have a VCR and nintendo wii hooked to the receiver via RCA and have not experienced any problems. Does anybody have any suggestions?
