Here is a fix. It is diffed against your original 0.08 version, Doug.

It makes GETOPTR set the LVI to the hardware fragment preceding the one
that's currently playing. In the case of Quake, that means Quake must
call GETOPTR at least every 3/4ths of a DMA buffer. Hopefully that
requirement should be relaxed enough. The alternate fix is to modify the
completion handlers.

I don't see anything obvious in the databook about how to make the
hardware loop infinitely without taking any additional input from us.

Comments, please.
