I tested your code on a Linux Ubuntu machine running OpenAL soft and here it was working flawlessly, the sample was played back at a slower playback (pitch 0.8) speed with a soft-echo effect like if played in a cave.

The only oddity i saw was a pulseaudio warning that came from the OpenAL soft library. I will have to look at that.

Did you run this code on a Windows or a MacOS X machine? If so there might be limited functionality in the OpenAL library’s we currently bundle for one of these two platforms.
