Sound cut/reduce problem

Foudroy

Hello, 

I'm using Teamviewer since a moment for gaming with a friend and we encountered a trouble.

We were on Teamviewer, I launched a game on my computer and my friend was looking. The sound is good but when he was talking, the sound  cut or was largely reduced. Is there an option on Teamviewer to not reduce the volume when we are talking ?

Thanks !
