Something else weird:
I have an on-board RealTek High-Definition audio adapter on my motherboard.
The sample plays very steadily with all three drivers on my computer (under XP), however there's two big inconsistencies:
1) Under OpenAL, the delay between the ticks is probably about twice as long. Much more ticks per second under DirectSound and FreeAudio than under OpenAL, although the OpenAL version remains very steady, no change at all in the delays... just spaced out further.
2) I have a 5.1 surround sound speaker setup. In your sample, FreeAudio and DirectSound play the sound through the front left & right speakers. Front center and rear left+right remain silent.
With openAL, all the front & center channels are silent but the ticks are coming through the rear left + right speakers instead.
(Which is not a good thing, unless you specifically intended to do so... The sound ought to come from the front for a typical 2D game, not from behind you)
