Participants cutting out when computer audio is being shared

[dempster21]

I attend a weekly exercise class on Zoom.  Our host provides music via shared computer audio.  On some occasions, not every meeting, when participants speak, the music cuts out.  I'm wondering if that could be caused by a bandwidth issue?  I've been trying to track down some resolution for this issue for some time and have so far come up empty.  So, if anyone can help me, I would be very grateful.
