Hi David,

First off, thank you so much for your replies to my post and apologies
for the delay in getting back to you!

I know your tried a few things using Jitsi Meet that don't look like
they will do what I am looking for but out of curiosity, how did you get
all of your audio sources to appear as the "microphone" input? I'm not
familiar with PulseAudio Jack Source so that may be part of my issue.
For me, when using Jitsi Meet in Chrome, the only audio sources I see
are these: https://imgur.com/a/wkAS0Al

Thanks again for your time on this.

Samir
