Sound Problem

During Zoom meetings my voice is heard fine both through the computer microphone and the headset microphone. I am trying to send Morse Code which is a series of dots and dashes ( a dot is a short tone and a dash is a longer tone. The tones are approximately 700HZ in frequency.) Zoom does not recognize these tones with either microphone. These tones were recognized on my older computer using  Zoom.

    How to troubleshoot audio issues
    Check if the microphone, speakers, or headphones are plugged in and not muted.
    Unplug the device, then plug it back in.
    If it's a bluetooth device, ensure that it is turned on and connected properly.
    Make sure that you are using a supported USB device for Zoom.

    I have the same problem. The answer to doug6 does not help.

    It seem there is some digital audio processing removing my morse code.

    I can talk it is fine. but if i code with similar volume zoom does not recognize the code.

    Help please.

    I, too, am experiencing this problem in exactly the same use case. I am wanting to participate in Zoom sessions where morse code will be taught, so it is important that the audio of the morse code I am generating on my desktop (though the speaker of a transceiver) is audible to other participants. I find, when I record my own meeting, that the morse is audible quite clearly for up to a second, but is then so severely attenuated as to be almost inaudible, and this happens regardless of which audio profile I use (I have tried them all, and have also tried turning off auto audio volume, to no avail).
