Is this an > expected behavior? I use Soundblasters, but I'm not sure I understand the problem -- do you want to change the pitch or not? Are you using the "expand" controls in the control panel? (They change the tempo, and need to be explicitly turned on, whereas the "speed" controls change the pitch). This stuff should be independent of the sound card -- it's all done in software.
