static on laptop audio

I see you sound like you know what you’re doing with regard to playing music on Zoom. I have been a fitness instructor for almost 5 years on Zoom now. I have a very simple setup. I play music on my iPad that is hooked up to a portable speaker. The speaker sits next to my Lenovo Windows PC and this setup has been working for years teaching Zumba, dance, yoga,etc. I have to update my version of Zoom but the lower versions always work best for me. Today I updated to version 6.0 because I’m going to have to do so by Thursday. My class reported static when I was talking and “Whooshing” sound when no one was talking. I am so worried about this because this is my livelihood. I teach senior citizens and many of them are home bound and this is a lifeline for them. Do you have any recommendations for me to try?  I don’t know who to go to but saw you responded to similar posts and I hope you can help resolve this issue. Thank you so much!
