Sharing audio with skype on the mac

Forum
macOS & Mac Apps

Hi everyone,
I have an issue on my mac; I'm not a experienced user of mac as I got my first macbook air 2 months ago and I'm in the learning curve.
The problem is that I can share the audio of my mac while sharing the screen in skype; no matter if I'm using the app on macOS Catalina or in my bookcamp partition in Windows 10, while using this mac, my caller is not able to hear anything from my devise.

I have been always a pc user and this never happens with a pc.

Any solutions?

Thanks in advance.
