pjsua and audio

[Wade Hampton]

I am on Fedora 33 and am trying to get pjsua working with my Asterisk
server.
Each time I try to make a call, I get an error about the audio device.  Is
it trying to use pulseaudio or alsa by default?  I saw one other post with
the same error from Fedora 27, with no answer...

The package is:  pjsua-2.9-5.fc33.x86_64

The error is:
  12:28:32.653            pjsua_aud.c !..Error retrieving default audio
device parameters: Unable to find default audio device
(PJMEDIA_EAUD_NODEFDEV) [status=420006]

Thanks
