<p>Tom, other interested people,<br>
</p>
<p>I finally got it working on a raspberry pi-4 with buster lite,
mostly thanks to the following articles:</p>
<blockquote>

<br>
Exactly seven years after your last post here, I'm there to ask if
you<br>
finally succeeded to resolve the issue?<br>
My case:<br>
<br>
1. Pi-4 with Raspbian buster und latest related FreeSwitch
distribution,<br>
apt-upgraded and updated just yesterday<br>
<br>
2. aplay is working both with the audio jack and with bluetooth
(although<br>
not simultaneously: as soon as I have a bluetooth audio connection,
the<br>
audio jack stops to work, and I cannot switch back to it with
"amixer cset<br>
numid=3 1", but aplay can continue to use the bluetooth connection
again<br>
after I issue "amixer cset numid=3 65536")<br>
<br>
3. it seems that I do not have any permission issue as both pi and<br>
freeswitch are in the audio group and related devices under /dev/snd
are in<br>
that group<br>
<br>
4. I have already installed alsaoss, libasound2 and libasound2-dev<br>
<br>
5. The output of "pa rescan" in fs_cli is the following:<br>
