i suspect that scheme sounds .mp3 or .ogg files internally, "cowbell sample" , "pull beard" using .wav files. it's known issue, , has been discussed on blackberry developer forums here , here, , here, simulator not have right codecs play sounds except .wav files. sounds should play correctly on actual hardware.
