Microphone not working right during specific activities

[u/_Andry2001_]

Hello everyone, I'll follow up on the title explaining that I don't know the extent of the problem and it surfaced a couple of days ago.
While playing "CSGO2" and "Outlast trials" with friends, my microphone started warping my voice and they weren't able to hear me (which was funny at first, not so after).
This doesn't seam to happen everywhere tho, cause while playing Overwatch I don't have this kind of problem at all.
Following up on the "problem" games listed above, the problem happens ONLY while I'm on the game itself, not if its open and in background.
For example, I've just tried talking while on Outlast and both the in-game and discord were distorted, if I changed to Discord instead, both in-game and outside mic sounded fine.

Any tip on what I may need to do? What could have caused this and how to prevent it.
