5.11.3 upgrade, now zoom does not hear microphone I have two MacAir platforms that were working fine with Zoom. But then the 5.11.3 upgrade occurred a few weeks ago, and now both no longer have any microphone coming through Zoom. iOS systems are OS X El Capitan 10.11.6 (old, I know, but the latest that MacAir can use) and Monterey 10.11.6 (current). Opening System Preferences/Sound shows that both have working microphones, but Zoom audio test does not see any level in or put them through to Zoom output. I have checked that Zoom has permission to use the mikes. I have uninstalled Zoom, restarted, reinstalled Zoom, all to no avail. There are no apps other than Zoom and Finder running. There is no antivirus software running. The Firewall is off. All was well before update 5.11.3. I have found no way to downgrade to an earlier version. Can anyone help?
