[Freeswitch-users] Configuring mod_portaudio for Debian built-in (JACK?) audio

Fri May 21 18:04:04 UTC 2021

I figured it out.

The 1st problem was the volume was set to 0. In order to fix that, logged
into the server and brought up a Gnome desktop, then used the audio tool to
raise the volume.

The 2nd problem was that when I plug something into the front audio port
(which is supposed to be able to be used for both a microphone and a
headset), the audio stopped being sent to the speaker, which was plugged
into the audio out jack on the back. Unplugging from the front audio jack
solved that problem.
