I'm in the same boat with portaudio when it's started with systemd.  When I disable it as a service and start it from the command line, pa devlist does return a list of devices.  Still workingon getting a call from portaudio to a station and vice versa.  Calling a station from portaudio device goes to voicemail and in reverse direction I never get a ring indication, just music on hold.

Exactly seven years after your last post here, I'm there to ask if you
finally succeeded to resolve the issue?
My case:

1. Pi-4 with Raspbian buster und latest related FreeSwitch distribution,
apt-upgraded and updated just yesterday

2. aplay is working both with the audio jack and with bluetooth (although
not simultaneously: as soon as I have a bluetooth audio connection, the
audio jack stops to work, and I cannot switch back to it with "amixer cset
numid=3 1", but aplay can continue to use the bluetooth connection again
after I issue "amixer cset numid=3 65536")

3. it seems that I do not have any permission issue as both pi and
freeswitch are in the audio group and related devices under /dev/snd are in
that group

4. I have already installed alsaoss, libasound2 and libasound2-dev

5. The output of "pa rescan" in fs_cli is the following:

Any clue, what could be wrong on my side?

Thanks!
