Public bug reported:

When installing jackd2 in ubuntu 18.04, i am unable to load the module-
jack-source.

Syslog gives me:

Dec  5 11:49:45 nvidion pulseaudio[7905]: JACK error >attempt to connect to server failed<
Dec  5 11:49:45 nvidion pulseaudio[7905]: jack_client_open() failed.
Dec  5 11:49:45 nvidion pulseaudio[7905]: Failed to load module "module-jack-source" (argument: ""): initialization failed.
Dec  5 11:49:45 nvidion pulseaudio[7905]: JACK error >connect(2) call to /dev/shm/jack-1000/default/jack_0 failed (err=Datei oder Verzeichnis nicht gefunden)<
Dec  5 11:49:50 nvidion pulseaudio[7905]: message repeated 5 times: [ JACK error >connect(2) call to /dev/shm/jack-1000/default/jack_0 failed (err=Datei oder Verzeichnis nicht gefunden)<]
Dec  5 11:49:51 nvidio

So the path to the shared memory location is not as expected.

When jackd2 is running i have:

hcw@nvidion:$ cd /dev/shm/
hcw@nvidion:/dev/shm$ ls
jack-1000-0          jack_sem.1000_default_1000_0_system  jack_sem.1000_default_jack_rack  jack_sem.1000_jack_default_1000_0_system
jack-1000-1          jack_sem.1000_default_freewheel      jack_sem.1000_default_qjackctl   jack-shm-registry
jack_default_1000_0  jack_sem.1000_default_jack_mixer     jack_sem.1000_default_system


So it seems module-jack-source / sink are guessing the wrong shared memory paths to the jackd2 server..

Versions:
jackd2                         1.9.12~dfsg-2 
pulseaudio-module-jack         1:11.1-1ubuntu7.1
