Hmmmm. I see that somewhere you use the command "load-module module-jack-sink". I use that to route Jack --> Pulse so I can see Jack's stuff in apps that use Pulse, like pavucontrol (Pulse's mixer). Not the other way around, i.e. to see Pulse's stuff in Jack. Confusing, isn't it?
I am under the impression that you actually want to do just that: see Pulse's stuff in Jack (i.e with qjackctl). I don't think that's going work. I don't think that Pulse --> Jack will work your way. As a matter of fact I don't know if there's a way to do that at all...
im also on mx-linux 21. If you are trying to get the whole jack and pulse thing going (sorry i only skimmed through your post, I have a narrow attention span at the moment ) , I'd like to share my settings which i've set once after install and never had any issues since. I use reaper and before launching anything, I launch qjackctl. When done and exiting reaper , I quit qjackctl so to utilize pc native sound ports. ( I don't need studio monitors for anything other than music production).
Installed are:
qjackctl
jackd2
pulseaudio-module-jack
a2jmidid
As a matter of fact, pacmd set-default-sink jack_out routes PulseAudio output to Jack.
In Qjackctl, this gives a "PulseAudio JACK Sink" plug with stereo output, which you can then connect to a Jack application. All pulseaudio sound is routed through this stereo plug. There are no individual pulseaudio application outputs. For that you'll probably need Pipewire.
On my (linux mint 20.2, qjackctl 0.9.7) system manually invoking pacmd is not even necessary anymore though: just installing pulseaudio-module-jack is enough to get both the PA JACK Sink and PA JACK Source available in Qjackctl.
If Pulse+Jack can be setup so easily just by installing pulseaudio-module-jack, and running qjackctl with jackdbus enabled, who cares about 'the most experienced and demanding users of JACK' dissuading it, if it works just fine that way?
Thanks for clarifying, this is exactly what I wanted to do and I'm doing this for years now without any issues. I used Cadence in the past where it is set up automatically, but now I'm using Qjackctl.
These are a set of urethane wheels fits many Rotary lift, Forward lift, & Hanmecson lift, model aj6 and rj6 rolling jacks. This fits jacks without any spring loaded function in the brackets that hold the wheels on. This kit Includes 4 wheel, 4 axles / pins , 4 bushings, and 4 plastic inserts for the pins. We also sell these in packs of two which will do one side of your jack. See our other listings for this kit.
After which there is no sound when I run jack, and spotify says it can't even play any sound. I guess I should revert that.
pavucontrol looks like this (I have tried to leave the top-most device both muted and unmuted), and both devices are completely silent.
At some several points during all my attempts, there was only a "Dummy output" here, but a reboot would 'fix' that.
Invariant through all these different runs, Xruns keeps going up, whether there is any sound or not.
The default card with the pulseaudio-alsa config tries to invoke a pulse server. but reads weird that it tries to invoke a dmix. FWIW, what is your end goal here? The mentioned applications so far don't really benefit from jack and you are introducing a lot of complexity for potentially little gain. Generic is also often a strange default codec to have what do you get for
but all of that is just skirting around the underlying issue. If you now start jack, therefore without the pulseaudio bridge/support, do you still get warnings/xruns? For the realtime permissions to be properly set up it should probably be sufficient to install the realtime-privileges package (and rebooting/relogging at the least)
Double check in cadence that the pulse sink that's connecting to your jack daemon is being routed to the correct card (ah wait apparently you did that, does refreshing the firefox tab after doing that help?). I'd completely expect that switching the sink to the "usual sound producing family sink" will not produce sound anymore, because jack is now handling that device. Maybe post during that situation
