OK, this program uses a direct DAC
writes rather than a DMA output.
The problem is that the output frequency
is unknown in that case and can vary.
So this cannot be fixed.
The only thing you can do is to adjust
the DIRECT_WRITE_FREQ constant in
linux_sound.h to satisfy the needs of
a particular program (but you will not
get a perfection anyway as the frequency
is not necessary a constant in that mode).
DMA-less output is an extremely absolete
method and fortunately is rarely used with
a DMA-capable cards like SB.
