Buzzing on Zoom Meeting while sharing screen

I'll just add another "me too".

I want to present at the university where the wifi security (802.11x) blocks Airplay. Cable is the only option.

I have exactly the same problem.

Apple seems not to care about it at all.

Sad and frustrating..

That’s what worked for me in Ecamm as well. I removed audio when using Screenflow and it doesn’t happen if I’m using QuickTime which is an Apple application. So not sure what’s going on.

I am using M1 Air and iPad Air 4th gen; MacOS 11.6 and iPadOS 15.0.2.

This one fixes the issue for me, except when you share the sound of the iPad.

I have the same issue after upgrading my iPad Pro. Seriously Apple get this fixed!!!

I have updated to MacOS 12.01 and IOS 15.1 and I am still getting the buzzing noise when I mirror my iPad pro to my iMac with Quicktime.

It is actually the audio that I use the screen sharing for, combines the game audio with voice comms on discord in my head phones and I am not sending game sounds through the head set mic.

Absolutely ridiculous. Apple you gotta fix that. Just bought a new iPad Pro and MacBook Pro and now this.

My iPad is Air 4th gen, but I have the same problem

I tried 4 different USB-C cable (original Apple), with an iMac and a MacBook Pro 15, alway the buzzy noise every 30 seconds when using Zoom.

I have the same problem with M1 iPad Pro for a half year, and Apple just keep ignoring this problem.

I have the same issue with my iPad Air 4 and my M1 Mac mini. It's like a ship horn.

I have absolutely the same problem with M1 iPad Pro 11" Wi-Fi + 5G.

I need to get my iPad sound, so I open QuickTime player on iMac,

File - New audio recording.

There is No applications opened in iPad, so it should be like this:

But every 31 seconds there is loud buzzing sound glitch appears:

It happens every 30 or 31 seconds.

If I connecting my iPad mini 5 to iMac - there is No problems at all.

But this new M1 iPad have sound glitch.

Problem still Not solved. We need support from Apple.

This “workaround” is not a solution. For anyone who wants a direct usb-c connection with all the benefits of that, you cannot rely on Airplay. I hope the buzzing noise can be fixed with an update. If it’s a hardware issue, we’re all stuck without being able to record M1 iPad audio via a usb-c connection, which is otherwise great since it’s low latency, high quality, and doesn’t require wifi being up.

I hope Apple engineers can fix this problem!

I listed my issue here: https://discussions.apple.com/thread/252997468

Same issue. iMac M1 + iPad Air or iPad Pro 11 (both newest generation) doing screen share over Zoom or QuickTime. The "anomaly" is an intermittent feedbacky "vmmmm ga ga ga ga") happens every 30-60s as described... it's unmistakable to anyone who has experienced it and is reading this thread.

The QuickTime "workaround" does not work if you are sharing the iPad's sound (which I need to for my use case). Airplay does work, but, as others have pointed out, you lose stability and screen share quality.

Please solve; this is make or break for my use case.
