[Freeswitch-users] mod_portaudio cannot find input or output device

The device(s) list fine with aplay -l and also as I mentioned sound files do
play out the speaker with aplay. When I built portaudio standalone from
portaudio's website, pa_devs also lists the sound devices fine. I tried
running FS as root and still same issue.

The first problem may be the default config you are using is going to cause
the console to load with a lot of errors that may just add confusion.
Portaudio streams are enabled but not documented by default and are throwing
atleast some of those errors (and for most
are not needed).   Try a much simple PA config like:
                <configuration name="portaudio.conf"
description="Soundcard Endpoint">
                    <param name="ring-file"
                    <param name="ring-interval" value="5"/>
                    <param name="hold-file" value="$${hold_music}"/>
                    <param name="dialplan" value="XML"/>
                    <param name="sample-rate" value="24000"/>
                    <param name="codec-ms" value="20"/>

Then see if you can get portaudio loading, however I believe the inability
to find any audio devices is kicking the error out.  You would want to try
running aplay -l from a command line to make sure some audio devices are
listed.  In addition try running freeswitch as root without the -u flag and
ensure that its not a permissions problem.
