Logitech 4K Pro Magnetic Webcam for Apple Pro Display XDR - Audio Issues

Has anyone else had issues with the above camera on OSX?

Essentially, when using Video Conferencing software, the WebCam audio locks up / crashes and ends up playing a random loop of sound.

I have tried many options to resolve this and in summary:

• The camera has been replaced twice by Apple - every single one has the same issue
• I have tried this on my Apple Desktop machine and Mac Book Pro - I get the same issue on both
• I have connected both via the display and direct to the computer - no difference
• The issue started when I was running on Catalina and has continued to occur with Big Sur
• I have applied all Mac Software updates and firmware updates - Logitech have not released any firmware updates for this webcam
• It seems to be particularly affected by Skype for Business

I have contacted both Apple Support and Logitech on this matter - Apple have tried to help (by replacing the camera and suggesting avenues of investigation) - However, they now want me to refer this to Logitech.

When I last contacted Logitech, they essentially said they were unable to help and suggested I obtain a refund from Apple.

The camera is a matching peripheral for Apple devices and I am using a full Apple setup - I would have thought such an issue would be important to both companies and they would have gone out of their way to attempt to diagnose the issue and resolve. Seem like my assumption was wrong.

One suggestion is to purchase a Brio camera and swap the magnetic bases.

Any suggestions?
