Tried everything including shutting down and restarting and upgrading.
Sound bar goes from mute to unmute but when I unmute I still don't get the sound.
hook the set top box directly up to the TV and turn up the TV sound volume using the TV's remote. does the sound work like that?
Were you able to fix it?
I had a similar issue with my Samsung TV and my soundbar I just got. I plugged it in the wrong way! LOL!
