[PlanetCCRMA] jack - howto?

After looking into it a bit more, I realized that jack does not automatically connect its inputs and outputs to the jack server unless explicitly told to (using the -i and -o command line options). Now that I do, I can see by looking at the jackd verbose output that it now is making the (apparently) appropriate connections, although I still don't get any sound out of it.

I have my alsa mixer settings set to record mic in - I can do 'arecord' from the command line and the input gets recorded, so that's not the problem. I can run alsaplayer with the jack output option, and I see it make the connection to jackd, and I can hear it playing, so jack output would seem to be working. I played around with the enable/disable button in jack, but still I hear nothing come out of it.

Yes, that is the problem... wait a little bit, I'm working on rebuilding
for rh9. Hmmmm, I hope that it will work on the beta but who knows...

jack_lsp lists all ports, there are utilities included in the jack
example clients rpm that enable you to connect ports from the command
line (can't remember their names),
