Sure, but the sound card DSP tends to be a pretty low powered DSP.

I think the typical signal processing in GigE or disk read channel
applications starts with analog to digital conversion at close to a
gigasample per second, and then doing DSP on the resulting data
stream.  Sound card DSPs are designed for data rates in the few dozen
k samples per second.
