Ingame sound gone when I'm in the TS?

When I'm in the TS, I hear everyone talking, they hear me, but I do not hear my own game anymore.

I turned everything on in-game sound settings, but somehow nothing works.

The game is Minecraft

The problem I have synonymous why it is I can't tell you

but I have found a small solution first you have to go into teamspeak and then open Minecraft then the sound is in Mc. Back there
