Hi,
It looks like it happens in PortAudio. I can't offer any fix for that,
but perhaps you can try using our native ALSA implementation instead.
Follow the instruction in https://trac.pjsip.org/repos/ticket/1016

These are fine. By default we will open the sound device at 16Khz, and
if this fails, we will try other clock rates, and whenever this fails,
PortAudio will throw that warnings. But it looks like we're able to
open it at 44.1KHz eventually.
Best regards,
Benny
