Ok will give it another go, thanks for the quick response guys!
Out of curiosity, is there anywhere where it stipulates the the firmware versions each component? And a summary of the firmware?
I don't know if I understood your question correctly, anyway, check this post from @emeric42 from this thread (I didn't find a way to link to a specific post here) to show the fw version of each subcomponent of the soundbar:
I'm in the US, running the newest firmware, which does nothing to resolve the issue for me. I'm having the exact same issues as everyone here -- constant disconnects and reconnects of rear speakers, no sound from subwoofer nor surrounds, with random momentary sound from each, and then nothing again.
Samsung supporrt is totally useless, and denies there's any issue.
You don't search...
Turn off soundbar and hold the options button for 5 seconds. You see firmware in display.
You must have:
M 0126.0 > B 1008.0 > H 0051.0 > FD 0040.0 > W 0241.0 > S 0136.0 > RR 0136.0 > RL 0136.0
If you don't have that, you don't Update the Subwoofer and Surround Speakers
