Meeting Mic always mute when speaker is unmute.

Problem During a meeting, my mic appears to be always mute if I have voice playback unmute in the settings. See screenshot.

As shown above,  in the first screenshot, when both playback and mic are unmute in the settings, the mic is inactive in the meeting. When I click unmute, nothing happens, if I clicked twice, the teamviewer crashes.

In the second screenshot, when I mute the voice playback, Mic actives.

Is this intended?
