Hy

I managed it to install Ardour 2.0.2 on my Ubuntu Feisty System.

But now, when I try to start Ardour there is a dialogue that says that Ardour isn't able to connect to JACK.

There are given 3 possible reasons for this problem:

1) JACK isn't running.
2) JACK was started under another user, possibly root.
3) There's another client called 'ardour'.

(this is translated from German into English)

I already tested whether JACK is running by typing

which jack

in the Terminal. The result was the line:

/usr/src/jack

so Jack is running.

I'm not able to solve the problem, maybe you are able to solve it.
Please help me,

Sapphire

1) the existence of /usr/src/jack does not mean that JACK is running

2) it appears that you did not install JACK from a Ubuntu package which is probably a better approach for you

3) you should also install qjackctl and use it to start jack, just because its easier and prettier.

qjackctl is installed

But maybe its enough when you just tell me how to start a jack server

You can use something like

jackd -R -dalsa -dhw:0 -r48000 -p256 -n2

Anyway, qjackctl may be easier to find the proper parameters for you (depending on your soundcard and kernel, "realtime" latencies may not be reachable)
