Receiver HDMI not showing in audio output list UN55MU800 with Soundbar N850
HDMI ARC not working.
I had same problem. My TV is Samsung UN55MU8000 paired with HW-N850 Samsung soundbar capable of Dolby Atmos.
It worked for about 4 months then started ocassional failure. If I unplugged the soundbar from power and plugged it back the TV would find it and reconnect back. Over time even if after power reset 15 times the TV would still not see the soundbar. Very frustrating. Both TV and soundar are really expensive. I called Samsung support and after a remote session with me they directed to me a nearby service centre. Service centre claimed they changed the motherboard and something else whatever. When I returned home it worked for about a week then stopped again.
Each time I unplugged the soundbar from power and plugged back the TV found it and when it tried to switch sound output to it the soundbar would disappear again. So back to square one. I went back to service centre again. They said they tested it on another TV (non-Samsung) and it was working fine on a different brand of TV and that nothing was wrong with the soundbar. When I returned home it continued the disappearing act.
I called Samsung support again and they said the best they could do was send the soundbar once more to the service centre.
I'm feed up. This is really very disappointing.
