Okay! So that was the wrong one. I have it now and I must say, it looks like an excellent program.
For Cool Edit Pro 2 you go to "Options" on the top bar click it and scroll down to "Device Properties", 3rd from the bottom. You can make your selections there. I very much doubt that Vista is your problem though so if it doesn't work for you maybe start looking at whatever player you're using.
Cheers!
