Precedence: bulk


just to be clear, the pi can generate fairly clean clocks for one of the aud=
io sample rates but the way the divisors work out it can only generate a ver=
y jittery version of the other, duty cycle bouncing around - not condusive t=
o 24buts of snr.

external crystals is definitley the best solution for both rates, but great c=
are in psu noise and rif is also needed if you want the best results.
