The DOC will only play a continuous waveform of up to 32k in length.  When
it finishes, you can have it just quit, start over, or start playing another
waveform.   I think if you were to make a "circular-queue" as you called it,
you would be writing to one half of that 64k while it's playing the other
half.  You'll know when it's done with it's half, because you can either
ask it, or have it tell you (i.e., either poll it or have it generate an
interrupt).

And yes, it steps through the data at different rates depending on the
frequency selected, and also the resolution.  By changing the resolution,
you can have it use every byte, every other byte, etc..

I'm sure somebody else can explain this much better than I can.  I never
was very good at explaining these sorts of things?
