Hello,<br>
<br>
I'm running Siduction (Linux), so I can't speak especially for
Ubuntu. <br>
<br>
I'm using a DAW within a virtual machine (QEMU/KVM), connecting
audio with jack-net to the Siduction host, where jackd (jack
daemon) is running.<br>
After Siduction introduced Pipewire years ago, my experience was
that Pipewire grabs all (USB) ALSA devices, preventing jackd from
accessing them directly. Pipewire only offers a jack API for jack
clients, but it couldn't work with the jack-net client. My
configuration was not working anymore, because jackd (and qjackctrl)
was not involved anymore.<br>
<br>
So I decided to deinstall pipewire on the Siduction host, and run
jackd as the main sound server again; within qjackctrl I configured
jackd to access my Focusrite 8i6 directly. Additionally I installed
pulseaudio-jack for non-jack-capable applications (alternative is
to run pipewire on top of jackd, but I have not tried). <br>
This works still as my low latency, distortion-free audio solution.
<br>
<br>
Not sure what the advantages of pipewire are; seems to aim on a
multimedia (video?) all-in-one solution, but as far as it is not
network capable it's useless for me. Also I'm not sure if the
Pipewire team sets high priority on the jack API in the future.<br>
<br>
If jackd is still available on Ubuntu, deinstallation of Pipewire
may be a (radical) solution. <br>
<br>
Regards<br>
<br>

<div>Hello.</div>
<div><br>
</div>
<div>Have you tried to changed the settings in qjackctrl, like
buffer size and such ?</div>
<div>Ubuntu is transitioning to Pipewire , artialy in 22.04 and
full in 22.10.</div>
<div>Pipewire replaces the legacy jack (emulation) </div>
<div>Maybe it is a reason maybe not.</div>
<div><br>
</div>
<div>I am, very worried to change to 22.10. my focusrite 18i20 Gen
1 suddenly has started to get many XRUN after 8 yeats w/o
changing the hardware.</div>
<div>But it seems many people are happy with Pipewire. (even it
may not have tested much with externa hardware)</div>
<div><span style="font-size: 14.666667px;">One of the reason I
have not transisition to 22.10 from 22.04</span></div>

<div><b>Subject</b>: [Jackaudio] Distorted sound after upgrade to

<div>Dear list members,</div>
<div><br>
</div>
<div>I'm quite new to Jack and just subscribed to this mailing
list.</div>
<div><br>
</div>
<div>First, let me say a warm Hello to everyone!</div>
<div><br>
</div>
<div><b>Now to my problem.</b></div>
<div>Since I upgraded Kubuntu 20.04 LTS to 22.04 (and also to
22.10), the sound I hear is distorted. Even when the sound
source is very quiet, the sound is distorted. As if somewhere,
the input signal is way too high.</div>
<div>I tried a few different settings in the Jack Audio
Connection Kit, at no avail.</div>
<div><br>
</div>
<div>Of course, I did ample research at Brother Google and found
seemingly similar problems. The advice that was given there,
was either not applicable to my situation, or was far beyond
my skills to actually digg that far into my Linux OS (I'm a
chemistry teacher at a Dutch high school, not an IT
professional ;-).<br>
</div>
<div><br>
</div>
<div>Thus made me decide to ask for help here!</div>
<div><br>
</div>
<div>My soundcard is a Focusrite Scarlett 2i2, The version of
the software is the following:</div>
<div>jackd: 5+nmu1; jackd2 & libjack-jackd2-0: 1.9.21;
qjackctl: 0.9.7-1<br>
</div>
<div><br>
</div>
<div>Below that is the output of the Messages in QjackCtl. Maybe
and hopefully, that some skilled eye finds some occurring
error ...</div>
<div><br>
</div>
<div>Thanks in advance !!!</div>
