There is method mentioned here to ommit this.

Alternately, Paula may signal the CPU to load a new sample into any of the four audio output buffers by generating an interrupt when a new sample is needed; this allows for output rates that exceed 57 kHz per channel and increases the number of possible voices (simultaneous sounds) through software mixing.
Also it's written here that D-Sam AMOS extension could play samples in 56kHz.

Quote:
Unlike AMOS, which can only handle samples at rates of up to 29 KHz, D-Sam can play back samples at a maximum of 56 KHz which - believe it or not - is a higher sampling rate than even a CD player can handle.
Edit: Anyway, there is only just theory for now that UHRES trick will do this, isn't?
