--> the version is equal to the version that I see through mod_portaudio in fs_cli

--> portaudio/bin/pa_devs find several "devices", but from among my physical devces connected through aux, BT and USB, it can only find the USB device

--> pa rescan in fs_cli, however, continues to report that no devices were found, not even the USB one...

Hi,

here is a short summary of my configuration and issue:

1. Pi-4 with Raspbian buster and latest related FreeSwitch distribution, apt-upgraded and updated on last Friday
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 issues as both of the users pi and freeswitch are in the audio group, which has rw access to the 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?

Thanks!
