No sound with Destiny 2 via headset?

I have had the JBL Quantum One since today. All great, good sound in every game except Destiny 2. Does anyone have a similar problem or any idea how to fix it? (Sound comes, but only from the speakers of the laptop).

Try to change the audio output device in the settings

Did it, I tried that at first, but it couldn't be changed, it always jumped back to the one originally selected…
