Audio issue

I use two devices when I am on a meeting. I have my laptop to look and talk into and my iPad to illustrate and teach with. After the new update whenever I hit “share screen” on the iPad it automatically connects to audio and does it again when I stop sharing which sends a screeching noise to my audience. I did not have this problem prior to the latest update and have been unable to find a solution. 

Has anyone else had this problem? If so, how did you fix it? 

Any suggestions are welcome! 

Thanks in advance
