I just bought a Samsung Q80a 85 inch Tv along with Q950a soundbar, and I've been suffering the eARC problems to the soundbar since day one. I talked to samsung tech support for 3 hours and still no solution, and I think the TV is the cause of the problem. No dolby atmos at all since the earc is not working, i'm stuck on wifi mode.
Anynet CEC is on, earc is on, hdmi 2.1 cable is connected to both earc ports on the tv and soundbar. However, everytime i try to choose the earc mode, no sound coming out to the soundbar. and if i tried to pick earc hdmi from the tv, there's no option for me to pick, because it only show (Wifi) after the sound output.
After a few resets on the tv and soundbar, unpluging every thing, then only plug the soundbar on first, then I got earc working at the soundbar at one time, then i start plug my tv box back on to the other hdmi ports on the tv, play movie for testing the sound on soundbar on earc mode, and added the soundbar to smarthing app, then about 30 mins later, earc sound output option disappeared again, no way i can find it back. Now the only option I got is (Wifi) mode on the tv for the sound output on soundbar...
Very frustrating, This may be the last samsung tv i buy.
I googled around the internet, lots of people said that it's the tv that cause the earc problem.
