Sharing audio problems

hello!

 I can't find any solution to a problem i started having last week. I never had it before and I've already tried several things but I can't solve it.

the problem is that every time I want to share screen, I can't share the sound if I have my headphones connected ( they are not bluetooth ones). If I disconnect them, my students can listen. I'd like to make it clear that the headphones are working correctly as I use them at all moments on zoom. This problem is only when I share screen.

Hope you can help me.

Thanks very much
