Audio problems, I cannot hear the people in a meeting. Please help

 

Hello,

 

I cannot receive audio from other particiants, although they have gone through all the options that TV offers. I have also gone through all of my options.

I can hear them on Skype so their equipment is OK. I can hear them on Placetel.

They can hear me, but I do not hear them. There were several participants and all of them can hear me but I cannot.
My speakers are OK. My PC is Windows 10, we all use Teamviewer 12.

I have a meeting tomorrow.
