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

I saw this error when i tried to start jack with optimistic period values.
try with something considerably higher to test that (add -p4096 -n3 -r96000
to the command line invocation for example). That's too much latency for
some (probably most) scenarios but it might get you a step closer to finding out
what's wrong.
Get a RT kernel setup too and try that.
cheers,
pete.
