  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 
 Run jackd in realtime mode.

 Is his kernel even a real-time kernel? I don't get that from the uname output...
What I mean is:
jackd -R -d firewire
That doesn't require a RT kernel. Don't expect FFADO to work properly
when jack doesn't run in realtime mode (-R). The same applies for ALSA
or other backends btw, but FFADO is particularly sensitive.
Greets,
Pieter
