I think it is fair to say at this point that Samsung simply doesn't care or they would have fixed this annoying issue by now. This is my second Samsung TV and I had a host of problems with the first one. I thought maybe the first one was a lemon so I bought another. The second one does the same thing that everyone has complained about - it will randomly revert to the internal speakers for no discernable reason.
Fool me once, shame on you. Fool me twice, shame on me. My fault for giving them my money for a second TV. NEVER AGAIN!
I will be willing to bet that their newest TVs do not have this problem. Did the problem start right about the time you recieved your last update? Are updates being pushed that break your TV so you will buy a new one?... This sounds like it should be illegal.
I have this same problem with a Samsung TV and Samsung sound bar. How can the same company not have a system that works together. I bought as a package.
I had the same issue and found a fix! Not sure if you still need help, but here it is. posted on youtube.

Try this worked for me on my samsung soundbar. Turn soundbar off then press and hold play/pause button on remote until soundbar display shows init ok. Your soundbar should now be reset. Now go through normal bluetooth set up on your tv and when you turn your tv off then on again it should auto connect to bluetooth soundbar. Hope this helps.
Sorry, but it's not a true solution to have to reset your customized settings each time that this issue rears its head. The issue shouldn't arise in the first place. And as for Samsung's repeated responses indicating that a resolution to this issue is considered to be a "feature request", well shame on them for that. We're not asking for bonus settings on the device. We're looking for a resolution to broken functionality.
I have the same problem with my QN65Q70R TV and HW-MS650 soundbar using an optical connection. There doesn't seem to be a pattern, and the firmware is up to date. Obviously, there is a Samsung problem.
