How do I get surround sound on GTA V on the Xbox One S?

While playing, I noticed that no sound comes from the rear speakers. Only on the fronts, the center and the subwoofer. According to the manufacturer, the game can be played with surround sound. What do I have to do?

Of course, I've connected the rear speakers correctly and set the receiver correctly. In film and other games, no problem.

In the game itself there's a setting in the sound options.

How did you attach the plant to the One and what did you set in the console settings?

And what about other games?

XBox One S → via HDMI → AV Receiver

For all other games and movies on the console, everything works fine.

Sound output is Dolby Atmos → shows it synonymous with the console and the AV receiver. There's a 5.1.2 set

Hmm, if it works on other games, only the ingame sound options are left. If I recall correctly, there's also a home cinema mode and you could also set the boxing, so the size of the room. But I do not give a hand on it because it's been too long ago.

Maybe the sound mode in the settings of the console on DTS or Dolby Digital.
