Sound problems with the new synapse update

Hi guys, after the last synapse update I have been having problems with the sound.
I will describe my problem:
When I'm playing something (when I open a game) the sound starts to increase and decrease by itself and it has a horrible quality, I've tried everything and I don't know what to do! 😤
But when I'm just on YouTube or Discord the sound is great.
Is anyone else having this same problem??
What should I do? 😓
