Share the video and sound should be together!

[henryusa2008]

I give lectures to university students, but some videos on the PPT screen share video not audio, why don't put two functions together?

BTW, for some online teaching programs, the sound quality is not good if demonstrating a musical instrument.  Zoom is only for speech?

Re. your second point, there's a setting that affects that, called "original sound for musicians"--see https://support.zoom.us/hc/en-us/articles/115003279466

Hope that helps,
