Zoom Sound Problem

During a Zoom meeting the sound from my computer microphone  and headset microphone work fine when I speak. While sending Morse Code (short bursts of sound at around 700Hz) Zoom does not detect the sound either from the computer microphone or the headset microphone. This has worked previously on another computer with Windows 10 and Zoom version 5.13.3. I am trying to get this to work on my new computer which has Windows 11 and Zoom version 5.14.0 I don't seem to have any of the "audio controls" you suggest disabling in your resolution tip.  Any help would be appreciated.
