openAl error raspberry pi

I am trying to load a longer sample using ofSoundPlayer on raspberry pi. I get this error

[ error ] ofOpenALSoundPlayer: loadSound(): couldn’t generate source for “”/media/Data/audio/Narration.wav"": 40964 AL_INVALID_OPERATION

Trying to load the same file as an mp3 also fails (in fact all mp3 sound playback with sound player on raspberry pi does not work).

Any workarounds for audio playback on the pi?
