Dear all,
how can I keep Jack from stopping by itself?
Thank you! oNNo

Hi ONNo,

This depends on your jack settings and on your hardware-software configuration. Please give here the info that you think is relevant and we will try to help.

Cheers! Pablo

Hi Pablo,
okay I have:

Dell latitude D630
AudioFire12 (firewire) interface

I am running:
Ubuntu 10.04 LTS - Lucid Lynx

these are my Jack settings...

starting up Ardour I get this log:

[ERROR]: AudioSetup value for interface is missing data
[ERROR]: AudioSetup value for inputdevice is missing data
[ERROR]: AudioSetup value for outputdevice is missing data

Thanks!

Hi,

In qjackctl, try

interface: (default)
instead of hw:0

Now, run raboof's script. In a terminal:

sudo apt-get install mercurial
hg clone https://realtimeconfigquickscan.googlecode.com/hg/
cd hg
perl realTimeConfigQuickScan.pl

And paste here the results of the last command (under code tags)

Also paste the contents of:

cat /proc/interrupts

Be patient.

Cheers! Pablo

Hi, thanks for the help!
I set interface to (default)

OK, there are some things you can improve in your setup. Take it easy, help would be better if it were interactive and forums are bad for interaction. I suggest joining #ubuntustudio channel in #IRC but we can try here aswell. I suggest you install the rt kernel and the rtirq-init script. Do a:

sudo apt-get install linux-rt rtirq-init

And reboot with the rt kernel in the grub menu.

Now, you have to check some things. You are not running the same linux as before. Check that the graphics work well. It is possible that you have to reinstall an additional hardware driver.

If you think that all is more or less OK, run this:

gksudo gedit /etc/default/rtirq

Enter your password and look at that file. You will see a line like this one:

Code: Select all: RTIRQ_NAME_LIST="rtc snd usb ...."

Change it to:

Code: Select all: RTIRQ_NAME_LIST="rtc yenta ohci1394"

Reboot with the rt kernel again. Now, check priorities:

ps -eo rtprio,cmd --sort rtprio| grep -i irq

If all looks fine so far, you can make that the linux rt is your default option in the grub menu. But I will cover that later.

Anyway, please, give more info on your system. Do a:

sudo apt-get install ffado-tools

Check the outputs of:

ffado-diag
ffado-test Discover
ffado-test ListDevices

And again, the quickscan script:

cd hg
perl realTimeConfigQuickScan.pl

More to come...

Cheers! Pablo

Thank you Pablo & Jeremy
how do I know if I have all jackd, libjack0, qjackctl complete?
You both mention linux-rt so I did:

Code: Select all: sudo apt-get install linux-rt rtirq-init

I selected restart and got:

Ubuntu, met Linux 2.6.32-25-generic
Ubuntu, met Linux 2.6.32-25-generic (herstelmodus)
Ubuntu, met Linux 2.6.32-21-generic

I selected the 5th and pressed enter.
I got:

mounting non on /dev failed: no such device

And then my normal Ubuntu studio opened.
I guess I did something wrong? :oops:

So far I am very happy with all the help provided.

The 'lm live chat' link above links to #linuxmusicians, but you can also change the channel to more active channels like #ubuntustudio or #opensourcemusicians

And then my normal Ubuntu studio opened.

You "only" changed the brain and the heart, not the skin nor the clothes.

I guess I did something wrong?

No. You did it fine.

I guess you made the change in /etc/default/rtirq but you forgot to give the output of:

ps -eo rtprio,cmd --sort rtprio| grep -i irq

Cheers! Pablo

Now, check priorities:
ps -eo rtprio,cmd --sort rtprio| grep -i irq

Yup. It's a bit of a bogus warning anyway. The Lucid Lynx real-time kernel doesn't have support for devtmpfs (a filesystem for temporary stuff), only for the older and maybe a bit slower tmpfs. I think it's hardcoded somewhere in some package (probably the mountall package) but since I moved to a 2.6.33 real-time kernel I lost interest in getting rid of that warning.

Ok, for Lucid the situation is a bit different since you don't have to edit /etc/modules and you don't need to add an extra udev rule. Ubuntu Studio Controls does that for you now (System - Administration - Ubuntu Studio Controls). Personally I still prefer to modify these things manually though. Hmmm, now that I read it all again, udev rules you create yourself should never go in /lib/udev/rules.d but in /etc/udev/rules.d...
