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

Here I am again with another update :)
The crackling audio with Jack is still a thing, the only news is that
I tried killing/stopping both pulseaudio and pipewire while using
jack, but that doesn't help, the issue persists.
I feel I might be getting closer to the source, but I don't really
know at this point.
Cheers,
Mario

New update.
Got back to Xubuntu 22.04 and installed Ubuntu Studio (via the
installer).
I'm on kernel 5.15.0-56-lowlatency.
I'm getting the crackle issue when using Jack (setup and started via
Studio Controls).
When using Alsa it's all fine. I tried streaming audio/video
(YouTube) and using Ardour 7.2.
I did change daemon.conf in /etc/pulse like suggested in the kernel
bug ticket.
Cheers,
Mario

Hi Roy,
Unfortunately that didn't work for me.
I managed to get rid of the audio crackle thing downgrading the
kernel (there's a known bug introduced with 5.13.xxxx - see my
previous post here).
I still get too many x-runs though, but I started thinking that it
might have to do with my AMD FirePro W2100 GPU.
Just a guess atm.
While trying to get to the bottom of my initial issue, I also
installed the AMD drivers for my GPU and that improved the audio
performance massively. No glitches/distortions even with low buffer
sizes, but my video was really sluggish.
On the internet I didn't manage to find any report with mine exact
conditions, but I found few posts here and there of people having
"audio issues" introduced by (the lack of?) AMD drivers.
I'll keep the list updated in case I get anywhere with this.
Cheers,
Mario

Hello Mario, i wonder if you could just do the
UbuntuStudio-controls config again. This fixed issues on my machine,
Good luck,

Hi,
Here's a bit more info and some updates.
I'm running Xubuntu 22.04.1 with Ubuntu Studio (everything
installed).
I'm using a Focusrite Clarett 8pre USB as audio device running
at 96kHz sample rate, 256 sample buffer size and 3 JACK period.
I'm fully up-to-date and the kernel is Linux
5.15.0-56-lowlatency x86_64 (I think the kernel got updated in
the last round of updates).
In the last 2 days I unsuccessfully tried to do the following
(in non-particular order):
*
uninstall pipewire - too many dependencies, so I gave up
on that
*
the combo
o
systemctl --user stop pipewire.socket && systemctl
--user stop pipewire.service
o
systemctl --user mask pipewire.service
*
re-install pulse audio
* in /etc/pulse/default.pa <http://default.pa> I added
"tsched=0" to the line containing "load-module
module-udev-detect"
*
edit the files in /etc/pipewire/media-session.d adding:
o
session.suspend-timeout-seconds = 0
*
install pipewire-pulse
*
replace pipewire-session-manager with wireplumber
*
re-install pipewire-session-manager and remove wireplumber
(this is actually the last thing I tried, so now I don't
have wireplumber anymore)
Nothing helped.
Then, after using:
*
systemctl --user status pipewire pipewire-session-manager
I realised I was getting 2 errors:
*
mod.rt: could not set nice-level to -11: Permission denied
*
spa.v4l2: '/dev/video0' VIDIOC_QUERYCTRL: Input/output error
I fixed the former adding
|@audio - nice -20|
to /etc/security/limits.d/audio.conf
I didn't manage to address the latter though.
The situation seems to have improved, not so much with
streamed audio/video, but with audio only (eg audacious) - it
might be too early to assess this though, since it was a late
night move.
I went from "totally unusable - glitches, pops and crackles
80% of the played audio", to "getting pops and crackles
sporadically".
Still makes my system unusable, since I mainly
record/mix/produce music on my computer, but all improvements
are welcome!
With audio/video from the internet though (mainly YouTube via
Firefox), I'm still getting terrible performance out of this.
Cheers,
Mario

Hi,
Recently I started having issues with the audio performance
of my system (Ubuntu 22.04.1 LTS).
It seemed to have started after my last update.
Simply running "top" I noticed I have "pipewire" running and
I was wondering if that could be the problem.
I don't know if that has always been installed as I never
checked before today, but I found online that several people
are having similar issues both on Ubuntu and Fedora.
Any feedback/recommendation is welcome :)
Cheers,
Mario
