There is the Chameleon. Several of the PCI DSP dev boards work in linux I
think. With the consumer audio targetted ones I think you end up paying
for the DSP code they come with (reverbs and such), which may or may not
be usable under linux.

It should be viable on host CPUs relativly shortly, 32bit floating point
is allreaddy the norm, and moving to 96k is just a binary order of
magnitude more processing, 18 months away if Moore's holds.
Granted its not as reliable as DSP tech (you end up wasting a lot of
cycles to occasional extra load and UIs), but I think its cheaper overall.
