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.

Here it is :

---------------------------

14:37:30.171 Statistics reset.

Cannot connect to server socket err = No such file or directory

Cannot connect to server request channel

jack server is not running or cannot be started

14:37:33.768 JACK is starting...

14:37:33.768 /home/drewc/.guix-profile/bin/jackd -dalsa -dhw:0 -r48000 -p1024 -n2

Cannot connect to server socket err = No such file or directory

Cannot connect to server request channel

jack server is not running or cannot be started

jackd 0.124.1

JACK is running in realtime mode, but you are not allowed to use realtime scheduling.

grep: /etc/security/limits.conf: No such file or directory

Please check your /etc/security/limits.conf for the following line

and correct/add it if necessary:

@audio - rtprio 99

After applying these changes, please re-login in order for them to take effect.

You don't appear to have a sane system configuration. It is very likely that you

encounter xruns. Please apply all the above mentioned changes and start jack again!

14:37:34.087 JACK was started with PID=22880.

14:37:34.088 JACK was stopped

14:37:36.101 Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server. Please check the messages window for more info.

Cannot connect to server socket err = No such file or directory

Cannot connect to server request channel

jack server is not running or cannot be started

--------------------------------

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).

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!
