Bob,
   Is Alsa running? cat /proc/asound/version   and   cat /proc/asound/cards

   Try a couple of simple things first:

(as a user)
jackd -d alsa -d hw

Does it work?

If it does then man jackd and look at the options. If it doesn't we'll
look at why.

Interesting options (from memory...)

jackd -R -d alsa -r 44100 -n 2 -p 256 -d hw

[mark@Godzilla mark]$ jackd -R -d alsa -r 44100 -n 2 -p 256 -d hw
jackd 0.99.36

JACK compiled with System V SHM support.
loading driver ..
apparent rate = 44100
creating alsa driver ... hw|hw|256|2|44100|0|0|nomon|swmeter|-|32bit
configuring for 44100Hz, period = 256 frames, buffer = 2 periods
nperiods = 2 for capture
nperiods = 2 for playback


Interesting. I'm not seeing realtime getting enabled. PlanetEdge kernel.

Anyway, give it a try.

Cheers,
Mark
