[LAD] RtAudio on archlinux

[Marc Nostromo [M-.-n]]

Hi !

This is is my first post to the list, I hope the topic is appropriate.

I'm an application developer and I've been using RtAudio/RtMidi for
years as cross-platform backend for audio and MIDI.
It never failed to work on me beautifully... until last week.

I've recently installed a raspberry pi 2 with the latest arch linux
distribution available and, for some reason, RtMidi doesn't report
connected interfaces. However, amidi does show them which makes me
think that alsa is properly configured.

[root at piewzei tests]# amidi -l
Dir Device    Name
IO  hw:1,0,0  MS-20 Controller MIDI 1

[root at piewzei tests]# ./midiprobe
Compiled APIs:
  Linux ALSA
Current input API: Linux ALSA
There are 1 MIDI input sources available.
  Input Port #1: Midi Through 14:0
Current output API: Linux ALSA
There are 1 MIDI output ports available.
  Output Port #1: Midi Through 14:0


I could bother the nice people at McGill but I guess there's something
very specific to my setup and I'd like to debug it myself.

Would anyone have an idea of what could lead to this behavior ?

Thanks for any pointers,
Marc.
