How to use jack and qjackctl on GuixSD?

How to use jack and qjackctl on GuixSD?

[-- Attachment #1: Type: text/plain, Size: 483 bytes --]

Hey,

I am a musician that produces a lot of things, and I use Ardour with jackd
for the most part.

On most of the other distros I've tried, installing and running qjackctl is
enough. On GuixSD it will not seem to work. It does seem to start it as
there is a PID, but cannot connect to the socket, does not run in
real-time, etc.

Any direction on where to go? I am a software developer as well and do not
mind getting my hands dirty at all, so let me know.

Cheers,

Drew Crampsie

I think this did connect for me, but didn't run as realtime
out-of-the-box.

qjackctl should have a log, can you post this? It should say something
about adding stuff to limits for the realtime issue and I'd be
interested in the message about the socket.

Do you run a Desktop Environment? I run with bare xmonad, which doesn't
start any sound servers, but if I log into XFCE I'll have a connection
problem. Even when you don't start any programs that use it, some applet
may start PulseAudio (for example).

Cheers, Mark

Yes! I am running XFCE and/or also have Gnome installed.

I will try xmonad ... is there an easy way to add it to config.scm so I can
F1 to choose it, and if not, where/how to I configure GuixSD's X to use it?

Otherwise, there is a pulseaudio jack sink that may work if I can be told
where to put it.

Thanks a bunch!

*grml* I think I messed up.

First note: 

https://www.gnu.org/software/guix/manual/html_node/Base-Services.html#Base-Services

See the bottom of the page. It defines a `realtime' group and it's
permissions. You might need to create this group and add yourself to it
or you might simply use the `@audio' for the `audio' group, where you
might already be a member.

Second note: It still doesn't work, but it's too late to look into
this. :( Could take care of this tomorrow.

Crazy, I had this running.

Cheers, Mark

Here is some earlier discussion of JACK on GuixSD:

https://lists.gnu.org/archive/html/guix-devel/2016-10/msg00479.html

Hope it helps!

Hi Drew,

hope this helps:

  - jack 0.124.1 wouldn't work for me either.  It was updated to 0.125
    2 days ago, and the upgrade fixed that for me.

  - about the realtime/limits.conf issue: I added the following 
service to my system configuration's services list:

             (pam-limits-service
              (list
               (pam-limits-entry "@realtime" 'both 'rtprio 99)
               (pam-limits-entry "@realtime" 'both 'memlock 
'unlimited)))

all of this courtesy of Ricardo Wurmus actually :)

Hey All,

Thanks a lot! Though I still do not have qjackctl working, Ricardo
Wurmus's help was a big plus. Now, `jackd -d alsa` works at the command
line, so things are starting to move up.

Will hopefully have more to report as working shortly.

Cheers,

Drew Crampsie

If it is still relevant, could you add more info and/or context?

Long since moved to other systems and cannot comment relevantly. Nothing
from me beyond "please close if closed".
