Desktop phone audio fails when I am unmuted

 I was using phone for audio for desktop zoom. I could listen. Everything worked fine until the host unmuted me, then the audio icon changed, and I could not interact with the host.

This is using desktop zoom for Debian, 7.0.0.1666

This problem has happened multiple times.

One time, I was able to establish a working system by hanging up the phone and reconnecting.

Another time, this method did not succeed, forcing me to move to Android app.
