[Freeswitch-users] Error loading portaudio module

[Giovanni Maruzzelli]

Sorry, the previous one was sent by mistake.

This one is complete:


Hi there,

you have to use the "default" ALSA audio device to share it, and to
have it automatically format and rate converted.

the "default" ALSA device is not the default portaudio device (not in
the portaudio version used currently by FS).

You have to find out what device id it has under portaudio.

But in this specific case, no device at all was found.

So, maybe portaudio was not commpiled with ALSA support (do you have
the ALSA development library installed?).

Also, after recompiling portaudio and mod_portaudio, you can launch FS
giving it the PA_ALSA_PLUGHW=1 environment variable, so portaudio will
use the plughw devices (that are automatically converted to the
desired rate/format) and not the raw devices.
