Trying to get Ardour to work but JACK isnt playing ball, I got the GUI but I still cant get the two to work happy together, any ideas, am I missing something??

Jack is more than just the gtk_jack. In order for Jack to work (worry about Ardour later) you have to have certain features enabled in your kernel and certain security features working. I mean, if you are going to just use it as root, then you will already have "real time priorities" but as a normal user, you will need to tweak the kernel. IF you are running it as root (not recommended at all - BAD IDEA) and you are running a gui for jack, then it lies in the configuration of Jack. I think you want to use jackstart with Hw:0 set. Then try to start it. If that still fails, then try some other options listed in the gui window. Once that is all set up and running properly, then start Ardour. If Jack is working, then Ardour will start without any errors. Hoped that helped a bit. Not very detailed i know, but you weren't very specific with the problem.

yea you gotta explain a little better what steps you have taken
how you start jack
when you say GUI you mean qjackctl ?
if no get qjackctl

i actually diagree with one thing Phorem said
it may be more advantageous to use jack/ardour with sudo rather than using a patched kernel

Actually, i agree, but i have used Jack several ways (as there is a couple of ways of using Jack while a normal user). I know of a long standing argument in the Jack mailing list about the whole sudo and "linux security" module issue. I personally agree with the kernel configuration. Some people like to sudo. As for being vague, i'm not going to do a Jack write up. Tons of those already exist and are just a google away. Plus,

"JACK isnt playing ball, I got the GUI but I still cant get the two to work happy together, any ideas, am I missing something??"

...that's a little vague. For all i know, he has jack working perfectly and his .asoundrc is borked or his actuall Ardour install is broken.
