Launching TS3 disables all sound, windows 10, bluetooth headset. all other app do not do that

Hi,
Launching TS3 disables all sound, windows 10, bluetooth headset. all other app do not do that.
i tried every google advice. making default, selecting other outputs. but even if i select output to speakers, it does not work from TS3.
Thus, when i launch TS3, no matter what sound output i use, all sound is disabled.
everything.
killing TS3, immediatly plays all sounds like normal. Its 100% a Teamspeak problem.

Fixed:
go to “sound” in windows:

disable headset recording device (sound >> recording).

sound is back
