Sampling speech on sparcs

I am looking for information on doing sampling of speech waveforms
directly on a sparc station using its built-in hardware.  The problem is
that the built-in sampling rate is 8K Hz (8192 Hz) and we want a sampling
rate of 8kHz (8000 Hz).  We don't want to do interpolation and decimation
to change the sampling rate.  Does anyone know of a work-around which will
allow us to directly set the sampling rate, ie. does there exist a
software settable counter which determines the sampling rate of the codec?
If not, any information on hardware solutions such as add-on cards using
the same T7500 codec or simple modifications to the existing hardware
would be appreciated.
