How to share sound with participant whlie retaining it as the host.

I am hosting a meeting and it requires that the participant hears what my computer plays. The only way I know to guarantee that is through the 'Share Sound' option. However, when I select that, I forfeit my ability to hear what I am playing as it is given away.

How do I retain the sound provided by my machine while also sharing it with my participant? Both of us needs to hear what is being played without one of having to make a sacrifice.
