Q-Symphony played through Wi-fi instead HDMI-eARC

[Mastajacobius]

Hello,

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.

Regards,
Masta

 I have a QN90B TV ans Q990B soundbar and it’s the same issue and was like other poster said it drives me crazy too when it’s not working as designed. 
I called Samsung Pro line and the first time resetting like the OP on the sound bar was their solution and it worked for a day or so and now I couldn’t get Q-symphony to work and it would be either TV speaker or the soundbar without the TV+soundbar option showing up.

I called again and this time spent another good hour on the phone and she also suggested the Anynet+ but still didn’t work until I saw this post and my work like other said only on Wifi.

Is the Wi-Fi option for Q-Symphony not as good because it’s compressed signal for the sound?

I just setup the Q700B and even after setting up Anynet+ it wouldn't give me the option for TV+soundbar through HDMI eARC. Only after I signed into the SmartThings app and registered the soundbar did the option come up

Qsymphony can only work with Wi-Fi, hdmi eArc/arc, can only transfer audio to a single source , in this case TV to sound bar, therefore disabling TV audio, in order for the tv and sound bar to both transmit audio at the same time it must be via Wi-Fi connections which can receive multiple and transmit multiple audio connections( multiple speakers and even multiple Samsung sound bars). Its the technology (ARC) not Samsung. The Wi-Fi audio will be degraded anyways so just keep the audio output on eArc. As four Wi-Fi sounding louder, yes because it’s degraded audio so lower quality is typically louder
