Hello dustyandy06,
Welcome to Apple Support Communities. We're glad you're here!
We see from your post that you've done some great work to test this issue on other devices and with another set of AirPods. Based on what you've shared, you still cannot hear your students and the video you're playing at the same time when using AirPods in a Zoom meeting. We'll be glad to share some tips to guide you.
- Since this is occurring in the Zoom conference, we suggest checking out the Testing computer or device audio support page.
- If you need further assistance, you'll find a link to "Contact Support" in the upper right.
All the best!
