Summary

Edit: This is from Steam
Mute in Background only works once or twice, then every time I switch back to the game, I hear a half second sound from the game and then its muted again.
I have to turn it off and on again for it to work again normally once or twice, then the situation repeats.
I've tried it with Escape from Tarkov Arena and Days Gone, both behave the same

Steps to reproduce

1.Mute in Background
2.Switch from game to other window, works fine
3.after one or two switches, it fails, and only gives a short half second game sound before muting itself
4.turn mute in background off and on again
5. repeat
