Ubuntu Studio Jack problems

bucovaina78 · 01-12-2011, 03:13 PM

Well,

I've tried everything so far and it's really eating up my nerves at the moment. I can't make jack to work properly. I've just installed the latest Ubuntu studio.

When I try to launch qjackctl, jackd isn't started properly:

Code:

22:08:12.841 Patchbay deactivated.
22:08:12.910 Statistics reset.
Cannot connect to server socket err = Bestand of map bestaat niet
Cannot connect to server socket
jack server is not running or cannot be started
22:08:12.939 ALSA connection graph change.
22:08:13.194 ALSA connection change.

When I press start:

22:08:12.910 Statistics reset.

I tried to change the output to /dev/audio and to /dev/dsp but both ways it protests... .

Something else I can do?

Thanks a lot

From what I remember... ALSA and JACK don't play together very nicely.

:O

That was rather weird... This is my shell session:

Code:

[joshua@joshua-desktop:~]$ qjackctl                               (01-12 23:27)
^C
[joshua@joshua-desktop:~]$ qjackctl -v                            (01-12 23:28)
Qt: 4.7.0
QjackCtl: 0.3.6
[joshua@joshua-desktop:~]$ qjackctl --verbose                     (01-12 23:28)
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
jack server is not running or cannot be started
[joshua@joshua-desktop:~]$ qjackctl --verbose                     (01-12 23:28)
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
jack server is not running or cannot be started
[joshua@joshua-desktop:~]$ qjackctl                               (01-12 23:28)
[joshua@joshua-desktop:~]$

First time (23:27) JACK started fine. Second time I was trying to get verbose, got version instead

third time and afterwards I got exactly the same errors as you, in the JACK error window... I will try again after a reboot (though that may well be tomorrow now, sorry...)

Welp, darn.

EDIT: <The next day - after rebooting>

Okay, I rebooted and got the same experience (worked first time but not after). However, this time when it opened the first time I clicked 'start' and it failed to start the server. It gave various errors (including being unable to find the command 'artshell', and I can find NO reference to that on the web at all :/), but the first error was "unable to start jack server". I know I installed various JACK stuff, but running

Code:

sudo apt-get install jackd

installed the packages

Code:

 jackd jackd2 jackd2-firewire libffado2 libxml++2.6-2

So it seems they didn't get installed properly before... The server now starts as long as I don't have my music playing in the background (using the ALSA server)

Does this fix your problem?

Today I gave up on Ubuntu Studio and tried Dream Studio. A distro closer to Ubuntu than Ubuntu Studio.

It looked very promising because in Live-mode from DVD JACK ran out of the box Yeah!! Finally. So I installed it and yes here we are again at ZERO:

Update: A kind guy helped me out on IRC. My jack command was wrong:

Code:

user: this command is wrong: /usr/bin/jackd -dalsa -dhw:0 -r48000 -p1024 -n2 -i1 -o1
 user: please do not use the -i or -o arguments (even from qjackctl, where the -i and -o are the "input channels" and "output channels" counts)
 user: they were wrongly exposed to users years ago, but have never been removed
<las> user: there is almost never any reason to use them, and using them to set the counts to one is definitely "wrong"

He solved my problem in 5 minutes

. I can't get any sound out of ardour though ... . I'll fix that

Ubuntu Studio comes with a lot multimedia applications?
How is it compared to Original ubuntu?
