Hi, I'm trying to use my presonus firebox sound card (which is firewire) with jack by typing jackd -d firewire (maybe no space between flag and argument? I tried both). I get this:

There's some memory allocation error too there.. Anyone knows any tricks? I'm on ubuntu 12.04 on a macbook (if it's of any importance).

I would like to point you to two commands. First:
$ man jackd
.. shows:
OPTIONS -d, --driver backend [backend-parameters ] Select the audio interface backend. The current list of sup‐ ported backends is: alsa, coreaudio, dummy, freebob, oss sun and portaudio. They are not all available on all platforms. All backend-parameters are optional.
There doesn't seem to exist a supported backend called "firewire".
Second:
$ aplay -l
.. will list your "PLAYBACK Hardware Devices" recognized by alsa.
If your card is listed there you could run jack with alsa backend and select your preferred device (e.g. hw:0, hw:1, etc..). Perhaps using qjackctl would make both easier. Otherwise you could try:
$ jackd -d alsa -d hw:0

Hi, Thanks for the tips. When I type aplay -l my sound card is not listed, so I guess I can't use it with alsa then. Also man jackd will display the messages you pasted in your email, but if I type jackd I get some comments which include this:
-d master-backend-name [ ... master-backend args ... ] Available master backends may include: alsa, dummy, freebob, firewire, net or netone.
firewire is there, though it says 'may include'. Typing jackd -d firewire --help, I do get comments though about the firewire driver (though this includes: Cannot create thread 1 Operation not permitted. It doesn't sound very good). I tried qjackctl too, and when I hit Setup and choose firewire and then hit start, it freezes, then dims, and finally crashes. After this every time I start it, it's window opens, but it's blank, and it crashes. I have to restart my computer for it to work again. If it's not possible to use this sound card with jack, is there any other way to use it?
Thanks
