Zoom Host's Music Garbled

My wife has been part of a weekday morning Zoom for some time now,  and has always had an issue where the meeting host often plays music at the start of the meeting.  The sound quality of the host's song audio is really poor, to where you can sometimes barely hear the songs.  However, there's absolutely no issue with his microphone when talking, even over the music. There are sometimes hundreds of others on this same meeting, none of whom seem to express any issue with the music from the host.  I've gone and switched laptops for her and get the same result.  I've turned off signal processing in Zoom Settings. (no change).  I've tinkered with other settings on the laptop, improved the wi-fi reception, etc.  I can't believe she's the only one having this issue if you were to say it may be from the Host's side.
