I just removed pulse audio but I am getting the same
errors. When I try to use jackd as the server path I get
this error.

18:53:06.576 killall jackd
jackd: no process killed
18:53:06.989 Post-shutdown script terminated with exit
status=256.
18:53:08.643 Could not connect to JACK server as client. -
Overall operation failed. - Unable to connect to server.
Please check the messages window for more info.

With all the other server paths I get this error.

18:54:03.126 JACK is starting...
18:54:03.127 jackstart -dalsa -dhw:0 -r48000 -p512 -n3 -S
-i1
18:54:03.133 Could not start JACK. Sorry.
18:54:04.932 JACK was stopped with exit status=255.
18:54:04.933 Post-shutdown script...
18:54:04.934 killall jackd
jackd: no process killed
18:54:05.387 Post-shutdown script terminated with exit
status=256.

Is there a beginner how-to for jack that explains what all
this stuff is and how to set it up? I can't seem to find
one which I can understand.

Greg.
