[Freeswitch-users] mod_portaudio on Raspberry Pi currently broken?

[Ken Rice]

Its not just those directories you¹ll have a problem with... There are also
permissions on the devices that are required for usb and other devices to
work properly... USB devices may or may not have the correct perms for
${whatever} group/user to access them

So I thought I'd try 1.2.9 mod_portaudio on RPi. Fresh install, running FS
as root, with the only change to add mod_portaudio to modules.conf.xml, but
mod_portaudio is unable to find devices. Alsa is working fine. I can aplay
files and get output. Any ideas on how to get a somewhat stable branch of FS
working with mod_portaudio?

we're testing the latest version of portaudio in a branch right now.
feel free to test and comment your findings on
