[LAU] No audio going between JACK and sound card

I just installed Fedora 9 but I am having trouble getting JACK configured properly. The only way I can get jack to start without failing is by using the 'dummy' driver. But I cannot get sound out of the computer (even though ardour is working properly and playing) or any sound into the computer. Is this 'dummy' driver an actual driver? I had it woring excellent in Fedora 8 but in my absent mindedness did not write down how it was configured. I do believe I was using alsa though. Do I need to set the path to the driver, it just says 'jackd' now? If someone could answer my questions or at least point me to a resource I would be very thankful. Greg.
