Well, you can always load the audio data registers programmatically,
however if you want to do this with any degree of frequency and
accuracy you will have to take over the machine and perhaps even
disable video/DMA.  Would make for some interesting demos, however
it's not clear that the Amiga audio circuitry is of sufficient
quality to really benefit from faster sampling rate - definitly
not with the normal anti-aliasing filter enabled.
