New Mumble issue

I've had my basic issues with mumble during the years.

The new problem I have, is not fixable by restarting mumble or restarting the game either.
Being an audio engineer I also know my speaker/mic setup is correct so the problem is not there.

facts:
1. I see myself in the right mumble channel (the right squad)
2. My in-game mumble icon pops up green/blue when I speak local and force
3. Other people can hear me
4. In-game I can't hear anyone speaking in mumble, on local or force. Other players mumble icon does NOT pop up.


I'm down to my last joint so I would be awfully thankful for fast advise.
