Thank you for the info.

For external hardware, I have tried or plan to try three setups:

    1)  a USB headset, Logitech, h340;

    2)  add the built-in webcam in an Asus VK266 monitor, this
        USB ID:

            ID 04f2:b11c Chicony Electronics Co., Ltd

    3)  a Logitech C920S webcam, with either its built-in microphone
        or the h340 USB headset.  After checking _many_ times, I
        finally found it in stock at Staples online.  It is
        scheduled to arrive in a few/several days.

Between my first question post and now, I did more experimenting
and found that a major part of the key is in browser settings to
allow Zoom in the browser to use the microphone and/or camera.
There was a great page that has some great screenshots, but I
evidently did not bookmark it and could not find in 7 days of
history.  The screenshots were for Chrome, but they were fairly
close to what Chromium has.

One key thing is that after changing the settings in Chromium, it
appeared to be necessary to restart the browser before the change
would be reflected in the Zoom test.  It _might_ have been
necessary to reboot the Pi.

I still was not able to confirm that the audio was working.

With the built-in webcam in the Asus monitor, the picture quality
appeared not exactly exceptional.

Thanks.
