For some ellusive reason my system (ubuntu 22.04) no longer starts jackd from qjackctl.
Am I out of luck as far as getting clean audio from csound? Are there alternatives that work as well? – in what circumstances, what level of use?

Why not just use Alsa directly? This is what I do, and I’m quite happy with the quality.
Okay, I used to need jack for csound (& other applications demand it) but I’ll be happy enough not having to deal with so many quirks!
I’ve never needed to use jack with Csound.
Do you have pipewire installed?
If so
then you will be allowed to use qjackctl (or qwgraph) to make connections and all the servers will sit happily next to each other without using wacky sinks or any of that stuff
otherwise it will break everything
~$ pipewire

Well that is better at least we know its running
As i said check packages… pipewire will conflict with all pulseaudio/jack/alsa packages it completely takes over your sound card and breaks regular sound servers. ie, no more jackd etc there are library conflicts. it instead replaces all of these, i spent some hours getting sound out of my browser cuz of this. but its cool when you get it to work.
[So far] I find no human-friendly interface for controlling pipewire.
qwgraph perhaps? Maybe I can find a link via The Evil Google – but not, apparently the lame duckduck. Could you send a link for that download?
Um, that search sends me to “qpwgraph”! Okay, something to try!
I now have qpwgraph 0.3.7; it looks good but is only showing me midi sources/sinks.
To show audio nodes? Do I need a later version, or merely to eliminate conflicting packages?
No you should just be able to output to jack or pulse like you normally do, as long as packages and modules are configured right (pipewire-jack/pipewire-pulse)
You will also gain the ability for pulse applications to be shown in the patch window
Also yes if you have old jackd or old pulse those need removed you can use qjackctl but it will be using pipewire’s jack, not jackd
Also it does have RT kernel functions
Yes, it’s working! (& now to listen to some things…)
Yay
Hopefully this helps someone else as well, like I said it took some time to fix my audio. Really great once it works
There’s an ubuntu package for the qpwgraph program. Then the first 3 steps here work to replace pulseaudio, & the resulting sound is great already!

I’ll finish the rest later, thanks!!!
