Audio turns way up on mac version 12.0.82953

Options

When I open Teamviewer the sound of the mac turns all the way to 100% everytime. When I'm listening music in the background, I get a jump scare and temporary deafness of the volume change. 

Changing the settings of the audio in Teamviewer only helps when the audio tab is active, after that it turns way back up.

It's very anoying this is happening, I have head multiple times that I'm partialy temporarely deaf when listening to music.

I'm using version 12.0.82953 on Mac OS 10.12.6.
