How to mix in desktop audio into meeting?

For my meeting that is a guitar course online I use my usb audio interface as audio source, because this way I can talk into the microphone and play the guitar as well. But sometimes I need to show a wav file to my students.  Is there a way to make it available for them to hear the playback from my computer? So when I play it on my computer in Media Player, they can hear it as well.

Such a function is often called LOOPBACK in softwares,  that is not a physical loopback in reality, it is only imitated, so that when you play something on the computer, the editor catches that sound can can record it, etc, just like that. Is something like this available in zoom?
