Audio "static" on Zoom Meeting

I have a tech support background, and I can't find an answer. I have a bi-weekly zoom session with one other person, and he has been telling me that I have static on my audio when I talk.  Switching to original sound ON helped for a bit, but now doesn't seem to.  He never has this problem with anyone else, and he has several Zoom sessions a day.  In addition I've never had this problem with anyone else either.  I will be trying a different computer for login, but does any one have any suggestions?
