Hi  @rross1  Welcome to the Canvas Community.

Good on you for branching out and using conferencing with Music. 

If you are using Big Blue Button then, as far as I know, if you put the link to the video in the conference then the students can watch with sound. This helps towards different bandwidth at students houses. But a simultaneous experience is tricky. 

If you use teams meetings built into Canvas there is a small box to tick 'include system audio' if you need sound. Do this when you share your screen. 

Sing out if you need a hand.
