portaudio is not finding any audio devices:

1. Pi-4 with Raspbian buster lite 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 users "pi" and
"freeswitch" are in the group "audio" which has rw-access to all related
devices under /dev/snd

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?
