Description
I was making a sound app that loads and unloads sounds for the Raspberry Pi when I noticed this error being thrown once I unload and try to load the same sound file again:
[notice ] ofApp: Creating new player at 0.001927
...Here the sound is being played for 2 seconds and once it stops, it is being unloaded and then loaded in again...
[notice ] ofApp: Removing player at 2.8134
[notice ] ofApp: Creating new player at 2.81569
[ error ] ofOpenALSoundPlayer: loadSound(): couldn't create stereo buffers for "/home/pi/openFrameworks/apps/myApps/ALSoundPlayerBug/bin/data/sound.wav": 40964 AL_INVALID_OPERATION
Added a git repo with an example here: https://github.com/kr15h/ALSoundPlayerBug

Start with the ofOpenALSoundPlayer loadSound() path and reproduce the unload-then-reload sequence using the linked ALSoundPlayerBug example on Raspberry Pi. Done means the same sound file can be unloaded and loaded again without the AL_INVALID_OPERATION error.
