New to BUD stuff here. Yesterday I was moving my dish around to see what I can get with my C/Ku dish. I found a couple of channels (can't remember the satellite but I think it was G3) that were showing nice clear views of Fox news stuff but there was no audio. A couple of other channels seemed to have no audio on the same satellite. Do I have to do something special to receive audio on those specific channels using my Coolsat 5000 or is this the way it's supposed to be?
