I'll assume that you don't have 3D.

Easiest thing to do is check the cable connections. HDMI needs to "handshake" to each device to work correctly. If they don't issues can arise.

You may need to disconnect the cable and reconnect it, perhaps blow some air into the jack to clear that up if needed.

See if it works, if not get another HDMI cable and try that out.



Does the sound dropouts occur with every disc you watch or just some?
