So I am at a loss as to what happened and what I can do. I have a Vizio PQ65 and a Samsung MS 650 soundbar. It has been connected via ARC for over 2 years working flawlessly until about 2 weeks ago or so. The sound works for a few seconds when you first turn it on and then just stops working and I have no idea why. The sound works when just playing through the TV speakers or if I connect via optical but nothing changed whatsoever and it's frustrating. I have no idea how to trouble shoot this. How do I find out if it is the tv or the soundbar that is the issue?
