Camera & Microphone access on iMac running Sequoia 15.5

[JohnC74]

Hi everyone, I have recently changed from a Windows PC to an iMac running Sequoia 15.5 and can't not get the camera or microphone to work with Zoom on the iMac.  I have troubleshooting sessions with Apple who are saying its a Zoom App issue and with Zoom who say this was a known issue with Apple Sequoia 15.0 / 15.1 but was to be resolved in Sequoia 15.2, which I am beyond.  There are no firewall or security restrictions in place on my iMac.  Can anyone confirm if this is still an ongoing issue with Sequoia despite it meant to have been fixed or suggest anything that you have done to get this working if you faced similar issues with Sequoia. Many Thanks for any help
