Please describe your issue in as much detail as possible:

Hello,

I launch the game "Move or die" through remote play together for a friend. I'm on Linux and he is on Windows. We are speaking through Discord but it do the same with anything else (Steam, Youtube video...).

I invite him to the game and he starts to hear what I'm listening. Example he can hear a youtube video that I launch in my headphone.

It look similar to https://github.com/ValveSoftware/steam-for-linux/issues/6625 and https://github.com/ValveSoftware/steam-for-linux/issues/6670

I not have the same issue with another games like "Ultimate Chicken Horse" or "Death Squared".

Steps for reproducing this issue:

1. Launching the game "Move or die"
2. Invite a friend through remote play together
3. Launching any audio sound (like youtube video), the other person will hear it

Let me know if you need more informations or test.

Cheers.
