https://stackoverflow.com/questions/46243029/how-to-get-the-audio-stream-from-pjsip-when-there-is-no-audio-hardware-device

If there is an hardware audio device driver installed the exact same code works fine on both OSes. I have compiled the PJSIP libraries with PJMEDIA_AUDIO_DEV_HAS_NULL_AUDIO enabled.

https://community.asterisk.org/t/solved-i-e-the-problem-never-existed-pjsip-with-no-audio-on-out-and-incoming-calls/78546
Hi! I started to use pjsip to connect to a SIP trunk (German Telekom). Internal calls are no problem. In- and outgoing signalling is also no problem, but there is no audio with these calls.

Distro and PJSIP: No Audio - FreePBX Community Forums

The PJSIP port is for signaling, the RTP ports (which you aren’t changing) are for audio. If you were unable to register then sure, the PJSIP port didn’t work. But you’ve both said you made calls and there was no audio. Therefore PJSIP signaling port is working. Considering PJSIP’s default is 5060, some providers block this port.

The missing "Turning sound device ON" in your app log may mean that the device is already on. When running pjsua the device may have been off when you issued the "cc 1 0" command. I've browsed your logs and I can't see any obvious reason why your app doesn't play sound. I would try to verify that the sound device is generating callbacks and

01:08:18.060 playfile.c Unable to open sound device: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [code=420006] Of course, checking the troubleshooting for sound on the PJSIP site (http://trac.pjsip.org/repos/wiki/audio-check-correct-device) is says you just need to run the PJSUA app - which I can't do because I can't find it.
