Have you tired resetting the sound bar?

Unplug the soundbar. Press the power button a few times so that you drain what ever power remains in there.
Wait another few mins. Replug the soundbar. Press and hold + and - volume keys for about 10 seconds until it displays "INIT" - "BYE"
Hopefully this works.
I'm ready to throw my MS650 off a 50 storey cliff due to ongoing HDMI ARC issues which Service 2 level from samsung cant fix.
