[LAU] Phonic Helix Board 24 on Fedora

Hi all, I'm trying to set up my Phonic Helix Board 24 on Fedora 10. I've added the CCRMA repository but I'm *not* running a CCMRA kernel. I have just used this repository to install ffado and jack. [jonathan@poseidon ~]$ uname -r 2.6.27.12-170.2.5.fc10.i686.PAE [jonathan@poseidon ~]$ rpm -q ffado ffado-2.0-0.6.rc1.fc10.ccrma.i386 Starting jack gives the output below. Running as root gives exactly the same output. I've made sure that all users have read/write permissions on the firewire port (chmod a+rw /dev/fw*) I'm a fairly experienced Linux user but I know very little about audio on Linux. Can anyone shed any light on this? I had the same Phonic device working on Fedora 8 some time ago but that computer is now a distant memory... Any help will be gratefully accepted! Thanks, Jonathan [jonathan@poseidon ~]$ jackd -d firewire jackdmp 1.9.1 Copyright 2001-2005 Paul Davis and others.
