I compiled mod_portaudio for rpi (arm11) in January. No problem.
I compiled it again this week. Problem. Logs show it can't find any devices.
So I copy the mod_portaudio.so and mod_portaudio_la from January to the newly compiled installation, and voila, devices found.
I did a git diff in src/mod/endpoints/mod_portaudio, and there have been a couple of changes in the mod_portaudio.c file, but nothing that would explain this.
Mod-portaudio source doesn't seem to have changed, just the way it's build. (Still version 1899, V19-devel.)
The newer mod_portaudio.la shows different dependences, and the new mod_portaudio.so is much smaller.
I think mod_portaudio is currently broken for raspberry pi and likely other platforms too. Anyone have any insight?
