I've had the NSZ-GT1 for a while and generally I like it but the sound cuts out now and again for no apparent reason. Its starting to do it almost every time I play a disc (blu-ray or DVD). I havent noticed it on streaming, but I havent been using streaming much lately. The receiver is clearly loosing audio only (picture is fine although being run through the receiver as well). It is not repeatable, ie Ill rewind the disc and the sound will play. Ive tried switching HDMI cables, to no avail. Any thoughts? Any help would be greatly appreciated!
