Check this program which tests the soundcards .
You will be able to see if your soundcard supports 192 and also its
frequency response.
Most cards support 192khz.

Subject: [hfsig] Performance of 24/192 soundcards?

There was some discussion at the ARRL/TAPR DCC of 24-bit, 192 ks/s
soundcards. Doing a google search on the subject leads to a few cards that
actually have 192 ks/s for both the ADC and DAC (and allow sampling at
192k). Unfortunately none of the sites list the frequency response of these
cards at the maximum sample rate (or any rate, for that matter).

Does anyone on the list have information about the frequency response of
these higher-performance cards? On the one hand, it could be just the same
as current sound cards (about 20 KHz.) On the other, they could have
something approaching 80KHz. Can't seem to find which by looking over the
various PCI and USB cards.
