Hi all,
I haven't posted here for some time now. I've been busy at work, but finally, I
have a linux box together that works again... It's a long story.
Still, I have a problem. When I started jack on the first lone soundcard, it worked fine.
However, I've added a second card, and now I'm having problems starting jack on
either of them.
The machine is an Athlon64 3200 on an nForce4 board. I'm running an up-to-date Planet
CCRMA on Fedora Core 6. The first soundcard (that did work in this machine) is an RME
DIGI9636, and the second is an RME 96/8 PAD.
Both cards are second-hand, but I have seen each of them working before - the DIGI9636 was
used previously with FC3 a year ago, and the 96/8 PAD was working in a Windows machine
earlier today.
I'm using qjackctl. Here is an excerpt of the messages as I attempt to start jack on
the DIGI9636:

And here is the output for the 96/8 PAD. This one gives a lot of xruns. If attempting to
start 'real-time', it just stops again straight away, as follows:

Where should I start? Am I doing something obviously/stupidly wrong? Please let me know
what other information might help.
Thanks,
