Hi, I have a raspberry pi b3+ and am running rasbpian (not sure which version- called 2018-11-13 raspbian stretch) and I installed the latest pjsip lib2.. When I run the pjsystest program, it doesn’t find any installed audio devices. I have an audio board that I added to the raspberry pi that I had to set up the board, but now it is the default audio devices and other programs (vlc, Qmmp) see, and can use the audio just fine. It is using asla. I don’t see any place to change the audio device if it can’t find it. I’m not sure what to do. For my purposes pjsua works great for what I need, but I’m not sure what to do for it to see the sound device. Any suggestions would be helpful. Thanks, Output from pjsystest below: M E N U : --------- 0: Tests 00: Run test wizard 01: Device Test 02: Play Tone 03: Play WAV File1 04: Play WAV File2 05: Record Audio 06: Latency Test 07: AEC/AES Test 09: Exit 1: Options 10: View Devices 11: View Settings Enter the menu number: 00 15:58:49.364 systest.c Running test wizard 15:58:49.364 systest.c Running Audio Device List Audio Device List No audio devices are found 1:OK 1 15:58:57.381 systest.c Running Audio Settings Error Error querying device infoUnable to find default audio device (PJMEDIA_EAUD_NODEFDEV) 1:OK 1 Audio Tone Playback Test This test will play simple ringback tone to the speaker.
