I'm by no means an expert, so take this with a liberal amount of salt, but I
read somewhere that the creative chipset is locked at a 48000Hz sample rates,
and all other rates are produced by resampling in software.

Could it be that snd maintains the pitch by changing to a lower/higher
sample-rate in hardware?

BTW - thanks for the pointer. I've been looking for something that will allow
me to slow down guitar solos enough for me to rip them off, this might be the
one :)
