I am seeking help.

I think having Jack on my new computer would be useful, allowing
audio capture.

My problem is so far have failed to get it to do anything (except I
did get jack to stop audacity doing anything). I found a web page
purporting to show exactly what to do in configure jack, qjackctl and
some other software.  Unfortunately jackd and qjackctl do not have the
same screen interface as the tutorial.

Does anyone know of a resource tho configure jack etc in its current
version?  Or explain to me about pipewire.... or almost anything to
get me up and running?

I am using openSuse 15.5 distro of GNU/Linux

I have also looked at alternatives but I do not have a Mac or Windows
computer.

i'm running gentoo on my laptop. i use pipewire-pulse for the built in 
interface which i let gnome control.

when i'm using csound, i use jack and run off an external usb interface. 
once i plug in my usb interface, i launch qjackctl. i setup the jackd 
parameters in the setup box to use the new usb interface, then press the 
start button.

then i launch csound with flags to use jack audio. usually it makes i 
good connection graph guess, but if it doesn't, i push the "connect" 
button on qjackctl and graphically edit the signal path. they recently 
made all the nodes movable in the connect(ion) editor. so it might not 
look like two side by side lists anymore. also, the audio, and midi 
device nodes are all on the same window, just different colors.

i'm not on that machine right now so i can't screenshot.

hope this helps. let me know and later tonight i can boot the laptop and 
clarify with some pictures.

one thing i have noticed, is that with pipewire, i seem to be able to 
grab the built in interface (hw:0,0) away from it (from pipewire? from 
gnome?) and then when i stop jackd (by pushing the stop button in 
qjackctl), it is returned. i dont know if its pipewire-alsa's pass 
through hw:0,0 or if its bare metal alsa hw:0,0

pipewire seems to be capable of becoming sources for alsa, pulse and 
jack so...

k.

Thank you for the reply.   am not sure that it helps me; I am way behind.

First  do not run gnome and do not know what it does in audio,

Second I cannot work out what one does to " setup the jackd parameters
in the setup box"for anything, nor what  am attempting to achieve,

I did not understand the rest of your message.  ~It shows te death of my 
ignorance!

Thank you; much appreciated.  I have jack and qjackctl installed from 
openSuse 15.4 repositories, and think audacity is jack aware.. For csound 
I assume I can use librtjack

I run a simple system. No desktop metaphor, just fvwm controlling X; xterms,s 
and emacs.

What does dummy mode do/provide?   How would ?I know if Csound and/or 
audacity connect to t?

  I looked at the screen shotand it looks similar to what I see.  Will try 
again
