I have the Insignia ns-50dr620na18 50 inch TV, and the Insignia NS-SB515 sound bar. I have them connected with a newly ordered digital optical cable, but for the life of my I can't figure out how to make actual TV audio come through the soundbar. I have the soundbar's source set to optical, but I couldn't find any clear info about how to do it on the TV. I set the audio to TV speakers off, I've also tried setting the audio mode to PCM (and everything else) all with the tv speakers muted, but I get nothing. Am I missing something?
