Dear Tom,
It doesn't matter. It works, it shows you all devices.
If you can run as usual user "alsamixer" and be capable to list the
soundcard and you run freeswitch where all files are owned by this user,
and start freeswitch as well as this user then you can access your
soundcard with mod_portaudio without any problems.
here is my unit file:
