Jack wont start [solved]

I'm trying to start the jack server to use with ardour.  I'm getting the following output on launch of jack:

19:00:02.971 JACK is starting...
19:00:02.971 /usr/bin/jackd -dalsa -dhw:0 -r88200 -p1024 -n2

Not sure what to do.  I'm using alsa, and I don't use pulse.

EDIT:  I selected playback only in ardour and it started.  I'm guessing the linux drivers for my card aren't quite up to snuff and it doesn't allow for playback and recording.

Re: Jack wont start [solved]

What command did you use?

When I run

jackd -r -d alsa

I get

could not open driver .so '/usr/lib/jack/jack_net.so': libcelt0.so.0: cannot open shared object file: No such file or directory
could not open driver .so '/usr/lib/jack/jack_firewire.so': libffado.so.2: cannot open shared object file: No such file or directory

too but it seems that these errors are not fatal - jack starts and stays open.

Re: Jack wont start [solved]

That's using Qjackctl.

If I use "jackd -R -d alsa" I get the following:

You can google "DRIVER NT: could not start driver" as I don't know Jack about jack - but it seems to be working here ;P
Or have a look at http://ardour.org/node/2733
