Conversation Between supaman32052 and buddy2017

Hey bud I have another issue I have an optical cord connected from my mag 254 to my sound bar.Though when I play some VOD movies there is no sound, the optical screen window flashes. Though I have no issues when the Mag254 is in TV mode .I believe it may be an error on the settings though what settings I don't know were to look. Any direction to correct would be helpful .
