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
