I have the same issue. Since Friday my surround setup is no longer surround. I have HW-K650 soundbar with 2 R3 speakers and all connected to 60inch Samsung KS7000. Everything was working fine for the last 6 weeks with some only minor issues (occasional connectivity issues solved by unplugging and plugging back the soundbar and speakers) and now I cannot use it in the surround setup. I did all I could like resetting all: the rear speakers, TV, my router. Even connecting all to a different network didn’t help. All the speakers can be found by the TV and create surround but then while playing movies from my NAS or anything from PS4 I cannot hear anything from the rear speakers. The only way to have a little bit of sound is to adjust in the volume settings the rear speakers to the maximum and the soundbar to the minimum. Unfortunately in this setup I can hear any sound from the rear speaker only with my head next to it. When using the multiroom app to play some music in the surround setup everything is working fine and only when it passes through the TV the problem occurs. From what I can read here it looks that on Friday there was some automatic firmware update that created this problem. I haven’t contacted Samsung yet but do you guys have any update, thoughts or fix for this issue?
