By re-spawning, I of course meant, you'll get default settings next time
you start qjackctl. So, all changes you made will be lost.

qjackctl configs can get corrupted sometimes. You can safely remove the
settings file, and it will respawn when you start qjackctl again.

The settings are in ~/.config/rncbc.org/QjackCtl.conf

FWIW I installed UBS 14.04 over the weekend.

I use qjackctl with multiple Audiofire12 units and extensive start up
scripts to wire eq's, crossovers, and mixers.

It just worked out of the box. THis rev I didn't even have to go find all
the calf and zita plugins. :)

Hi,
I did use my actual username, thank you!  I did that first, and then got
the other e-mail.
It seems my issue is actually something with qjackctl, as I have found
that I can get a working setup using jackd from the command line, and
then use qjackctl to set stuff up...
I had become accustomed to qjackctl 'just working' as a frontend for
jackd, so I figured there was an issue with something in the drivers,
etc... 
I will definitely post my solution when everything is resolved.

If you want to add somebody to a group, use the  username , not $USER.
If you want a script to test, if somebody does run this script with user
or root privileges, use  id -u  , not $USER. I guess what output you get
for $USER depends to your setup or distros default setup, but a
username  always is a  username  and the output of  id -u  always gives
information about the privileges.

[rocketmouse@archlinux ~]$ echo $USER $(id -u)
rocketmouse 1000
[rocketmouse@archlinux ~]$ su
Password: 
[root@archlinux rocketmouse]# echo $USER $(id -u)
rocketmouse 0
[root@archlinux rocketmouse]# exit
[rocketmouse@archlinux ~]$ sudo -i
[sudo] password for rocketmouse: 
[root@archlinux ~]# echo $USER $(id -u)
root 0
[root@archlinux ~]# logout
[rocketmouse@archlinux ~]$

I decided I would reply back on the original thread since the other was
becoming cluttered.

So far ffado list has been very helpful.  I can apparently connect and
run my box just fine using jack via the command line, and then qjackctl
will work.  So, there is something that changed in the qjackctl setup,
between versions.  The end is in sight here!  Thanks everyone for all
the help you have given.  Thanks to Kaj for pointing me to the ffado list!

Well, I still have the errors I posted despite the reboot, so there must 
be something I am missing.
 will try the liveDVD when I have a chance to see if it is present 
there as well... if it is, then it is a bug, if it isn't there must be 
some other configuration I am missing

$USER is an environment variable. It's more correct to use your username
directly, since using $USER only works if you are logged in as that
user, when running the command - with sudo (if logged in as root, root
will become a member of audio group).

Jack uses the audio group for getting access to realtime. ffado uses it

That's pretty much it.

You can install linux-lowlatency if you need lower latency (which you
will if you do any form of live recording and need to monitor yourself
through the computer).

I know they are Libre software... I simply meant that I'd rather install 
it than use a Live system.  The only thing I am tweaking is QJackCtrl in 
order to make it see the FireBox, in 14.04.  the presets can be easily 
reset, as I have a 'safe' saved preset using alsa and and experimental 
preset for firewire



but thanks for your info.
I am in 12.04 right now, but if you need me to run some commands
and post the output I would be glad to. Presonus Firebox is
already on FFADO (which is why I got it).

Unfortunately this is not the case with Ubuntu (not Ubuntu Studio). So 
that is why I am posting to the Ubuntu Studio list, in order to find out 
what is different in Studio, so I can simply configure whatever it is by 
hand to work.  And I appreciate you spending so much of your time trying 
to help me!



I got the interface specifically to use in Ubuntu... but 14.04 is
having issues with it.


presonus doenst officially support linux.. RME does AFAIK
I know, it says that on the FFADO page, but in the comments someone 
mentioned that it did actually work 'out of the box' in Ubuntu 12.04, so 
I figured I'd get it (12.04 is supported for long enough anyhow)



To enable it in Studio 12.04


there is no "enable" process for the firepod i have from presonus. it 
literally just runs when i have proper supported firewire chipsets
hmmm... you don't even need to start the mixer?  I may try without 
starting the mixer... but surely you need Jack, right?



Mike, I really appreciate all your patience and hard work in helping me 
to resolve this issue with 14.04.  either way, I am glad to have 12.04 
working splendidly with it.
I always enjoy the process of getting some old 'broken' computer and 
giving it new life with Ubuntu (or in some cases Debian or Fedora... and 
once in a while Puppy).
Thanks for helping me turn this old Mac someone thought was useless into 
a recording studio :)
I am not sure I can say thank you enough times, but I do really 
appreciate your help!

Well, I am now dual booting [well... triple booting as I need MacOSX for

I use Ubuntu 14.04 and Ubuntu Studio 12.04.  It works out of the box in 
Studio 12.04

I am using a Presonus Firebox.
I prefer to use only FLOSS and only want to install it rather than use a 
liveCD/USB/DVD (unless it is puppy), but thanks for your info.
I am in 12.04 right now, but if you need me to run some commands and 
post the output I would be glad to.  Presonus Firebox is already on 
FFADO (which is why I got it).
I got the interface specifically to use in Ubuntu... but 14.04 is having 
issues with it.

To enable it in Studio 12.04
Open the FFADO mixer, wait until it loads the device.
Open QJackctl and change it to firewire
Open Audacity (I haven't tried it in Ardour yet... I wanted to just see 
if it works) change it to Jack

Voila!  Working as expected.

So why doesn't it work in plain Ubuntu 14.04?  I tried MANY things, and 
all of them were useless.  Jack works fine with Alsa but not firewire.

If you like I can later post the output of the errors.

The other issue is Ubuntu Studio 14.04
I downloaded the 32bit live (DVD) from current yesterday, and
Ubiquity goes fine until the place where I can choose the packages
to install.  Then a dialog pops up with a bunch of  and

between the EFI boots on the USB, and none of those work.

Thanks for your help!


when i migrated my production rig to linux, using a firewire interface 
(as well as testing with may other internal and USB interfaces) these 
are some helpful tips that i found made the transition possible.


1. work from a live CD. there are several nice live CD's these days, 
such as our ubuntustudio live CD. when i say "live CD", i just refer 
to the iso image, downloaded and running from whatever you need.. DVD, 
USB, whatever.. while testing with the live CD's, you can easily tweak 
*any* and *all* configurations, without the fear of breakage. this is 
also an easy way to test different kernel versions and JACK versions 
with your hardware. i like to use an ubuntu 12.04, and now, the 
upcoming 14.04, as well as AVlinux's live iso
2. what is the issue? is it the firewire? or JACK? or permissions? or 
what?
test things as independently as possible. dont land in a new os, fire 
up jack, with a piece of firewire hardware you dont know is supported 
in linux. start with the internal audio device, and learn to configure 
and run JACK using it. then, you can move forward knowing your JACK 
configuration is working or not.
3. the firewire chipset *can* make or break linux support. you can run 
"lspci" in a terminal and see what chipset you have for firewire.. 
ideally, you have texas instruments.. if not, i have a few others that 
work well, and also, a few that will never work in linux.
4. i have had laptops with IRQ issues relating to sharing IRQ for 
firewire with USB ports i was using. you can check this in the 
terminal with "cat /proc/interrupts"
5. keep in mind, none of the vendors of any of the hardware you have 
have promised you linux support. a team of experts from many different 
companies have come together for years and years to work with each 
other and make sure that your hardware works in a different operating 
system. you are basically deciding to take that responsibility on for 
yourself.
6. temporarily running jack as root (which is not something i would 
want to do all the time, continuously) can help troubleshoot 
permissions. running "gksudo qjackctl" allows one to start jack as 
root.. if jack has been failing, but runs as root, then, you know that 
the hardware configuration in jack works, and that the issue is more 
likely to do with permissions.
7. in qjackctl, there is a "messages" button that can have lots of 
helpful information..


feel free and share any terminal output here for any of the commands, 
or the jack GUI error messages.. i suggest joining the IRC for 
realtime help.

[ubuntu-studio-users] Firewire interface
