Hi,
Yesterday I decided to give this another go, and it seems like I might
have found a solution.
I re-installed Xubuntu and then added Jack to check if the issue was
there, and it was there indeed (using the generic kernel).
So, I used UbuntuStudio-installer and gave it another try (at this point
using the low-latency kernel), and the issue was still there.
It seems as if Jack was the issue (or at least everything was pointing
there), hence why I decided to install Pipewire and configure it so that
it "replaces" both PulseAudio and Jack, and that gave me the best results.
I definitely don't get that annoying crackle every few minutes or so,
and (after a bit of time to set it properly) the workflow doesn't seem
bad at all.
Of course, I still have to properly check the performance, but for now I
got rid of the main issue, that made my machine totally unusable.
Cheers,
Mario
