Changing amplitude on sound file has no effect

[tyhdefu]

Setting the amplitude seems to have no effect on the resulting sound.

Example code:

SoundFile pegHit = new SoundFile(p, "peg_hit.wav");
pegHit.amp(0f);
pegHit.play();

You can still hear the noise even though there should be complete silence.
Using play with the amplitude parameter seems to have the same effect.
