5.1 sound in Fortnite?

I bought a 5.1 surround sound system and read that Fortnite supports 5.1 and I wanted to ask how to activate it or how I can have 5.1 in Fortnite, I played a round and didn't have 5.1.

How did you connect the system, I would recommend via HDMI or Toslink because the cables transmit the signal digitally.

You then have to call up the Windows sound configuration again and configure it correctly. If you are using full-spectrum speakers (3-way) then you have to tick the selection of the full-spectrum speakers. Without this hook I had 300 problems with my Canton Karat.

I don't think you would have to set anything in the game.

Found the error, had to turn off the graphical display so that I have the sound over 5.1.
