Hi all,
does ne1 have pointers on how to do generative audio on the Rpi ?
(without using an external sound card)1- I've tried the bundled example audioOutputExample, but I've got:
RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (default), No such file or directory
using soundStream.setDeviceID(1); works for the HDMI audio out
using soundStream.setDeviceID(0); doesn't produce any output (mini Jack)2- I've tryied ofxTonic -> doesn't compile on linux arm
3- I've tried the regular of. way (ofSoundStream), but I can output only on the HDMI audio - which is no good for me -, BUT after a short time, the RPi hangs. ("unable to write to buffer")
4 -ofxSuperCollider and ofxPd do look overkill and way too complicated for my purpose.
Note #1: I've got a RPi B, not the B+ (which is supposed to have better audio).
Note #2: the ALSA driver seems to be locked on device_1, which is the HDMI audio. I can't find a way to force output on device_0 (mini jack).Any help truly welcome.
