Sorry but I don't see links but common settings I try are as follows. Look for places to change the audio to PCM, Stereo and others on the TV. Sound bars often are silent if you send them 5.1 sound.
I have a Samsung TV - model UN46C8000XP and I just got a Crystal Surround Air Track. I used the Optical Adapter (BN39-01154M) as is required and plugged it into my TV and the Crystal Surround Air Track with an optical cable. I changed the TV to external speakers (and tried without this change) and I get no sound . What is the problem?
