Firepod and Ubuntu Studio... Help please, before I quit! :)

[Julián Fernández]

Hi guys... My first post here.

I installed Ubuntu (via Wubi) a couple of days ago and I was fascinated from day one... Everything seem to be good.
The problems started when I tried to install my Presonus Firepod... I tried every guide I found on this forums but I can't make it work...

The last guide I use was this one:

http://ubuntuforums.org/showthread.php?p=2833020

Right now this is the error I'm getting when I try to use Jack:

`default' server already active
00:51:24.332 JACK was stopped with exit status=1.

BTW, Jack won't let me choose the number of inputs and outputs of my FP... That must be wrong, right?

I need help, pleaseeeeeeee I don't wanna go back to Windows!

I have my firepod up and running fine, hopefully I can help you do the same.

First, we'll try to narrow down where things are going wrong for you.
What happens when you run the following command from the terminal (after a fresh reboot of the computer while the firepod is on and plugged in):

jackd -R -dfreebob

Also, what's the output of this command:

uname -r

THANKS A TON!

After jackd -R -dfreebob i get this:

jackd 0.109.2

BTW, When I updated to Ubuntu Studio (through Synaptic), after downloading an error occur... something like this:
E: ubuntustudio-audio: dependency problems - leaving unconfigured

What should I do about it?

Thanks again!

Okay it looks like you have run into the raw firewire permissions error.

First, let's try to get your ubuntustudio-audio package installed properly. Go to the terminal and make sure apt-get has finished installing all the packages you have previously asked it to:

sudo apt-get install -f

Then once it's finished, manually configure the ubuntustudio-audio package (the last command may have done this already, but it won't hurt to do it again for safety's sake)

sudo dpkg -reconfigure ubuntustudio-audio

Now go ahead and try the jackd -r -dfreebob again, if you get the same "operation not permitted" error then do the one of the two following operations:

1) GUI method (easier for beginners)
-Open System->Administration->Ubuntu Studio Controls
-Check the box marked "Enable raw1394"
-(optional step) while you're there it's advisable to turn on memlock and adjust it to about 90% or so (mine's @ 95%)
-Click apply
-Click close

2) Command Line method (helps gain better understanding of the process, and makes sure things are done properly)
-Open a terminal and do

sudo gedit /etc/udev/rules.d/40-permissions.rules

-Find the lines that read something similar to:

KERNEL=="raw1394",                      GROUP="disk"
KERNEL=="dv1394*",                      GROUP="disk"
KERNEL=="video1394*",                   GROUP="video"

-Change it to:

KERNEL=="raw1394",                      GROUP="audio"
KERNEL=="dv1394*",                      GROUP="audio"
KERNEL=="video1394*",                   GROUP="video"

-Save the file, and exit gedit


Now you should be able to get jackd running. If you still get an error when you execute 'jackd -r -dfreebob', please post that error. If it's the same permissions error, then try rebooting (I don't think a reboot is required but it may be to refresh the udev rules).

If you do have jackd running from command line, then try getting it running via qjackctl (aka. jack control); if that gives you an error then you need to adjust your settings in qjackctl's settings window.

Hopefully this all helps; post back with how far you get.
