Hi,
I'm using PJSUA in a python script to play incoming call audio on the sound device.
The problem I'm having is that sometimes the sound device isn't closed even after the call is disconnected, although I see in the logs that the sound device was closed. This happens intermittently and not always.

I'm using PJSUA in a python script to play incoming call audio on the sound device.

# Logs

USER PID ACCESS COMMAND
/dev/snd/pcmC0D0c: root 8357 F...m sip_speaker.py
/dev/snd/pcmC0D0p: root 8357 F...m sip_speaker.py
I'm using the same code as here, except that I'm doing a little more work on call state change (to disconnected) and on incoming call. I'm able to reproduce this problem by simply adding sleep(3) at line 59 & 115 of my code and making calls in rapid succession.
I'm not sure what's wrong with my code, but it looks like some sort of a race condition.
Thanks and regards,
