[LAD] RtAudio on archlinux

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@piewzei tests]# amidi -l Dir Device Name IO hw:1,0,0 MS-20 Controller MIDI 1 [root@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. -- http://marc-nostromo.com
