Hey there!
Hope you're doing great! 
I am facing an issue right now where I do not have sound on my Teamviewer 14. Currently, I am using ElementaryOS (Debian Linux), I've tried connecting to PC with Windows 10, I had no sound. And when I've tried connecting from PC with W10 to my Linux computer, I had no sound either. So both ways sound doesn't work.
Any solutions for that?
