Can you quantify the lag? How much is it lagging? Lately I've been
seeing my footstep sounds, which are individually triggered right and
left steps, take 2-50ms to trigger for some reason. I'm not sure if
it has something to do with the way the OGG is encoded, but I feel
like it could. Perhaps the SoundPool author would like to chime in
and give us some hints?
