I have Samsung QN90A TV and Samsung HW-Q700A soundbar. I plugged the soundbar into TV via HDMI-eARC cable.
As I said in the title, my problem is that Q-Symphony is only available to play via Wi-Fi connection instead of HDMI-eARC cable.
I can only have soundbar play via HDMI-eARC, but not TV speakers + soundbar, that is only restricted to Wi-Fi.
When I go in Settings > Sound > Sound Output to turn on Q-Symphony:
Only option I get is "TV +[AV] Soundbar Q700A (Wi-Fi)" instead of "TV +[AV] Soundbar Q700A (HDMI-eARC)".
This surely means my audio output is limited when watching content with Dolby Atmos and alike, right?
Also, for whatever reason - whenever I turn on my TV, soundbar doesn't turn on autonatically, so I need to turn on Q-Symphony manually every time....
This is really driving me crazy, I really need some help here please.
I am having exactly the same issue with my QN95A TV and the HW-Q700A. I am using the HDMI cable provided in the box
So I did a factory reset on both my TV and soundbar which fixed the problem... sadly I cannot provide any more troubleshoot info as in why and how.
Hope this helps fixing your problem.
