Thank you, that cleared the error. But, when run the jacktrip command it gives below error. any idea on how to fix it ? I made sure the variables are correct.

So, i want to clarify if I'm doing it wrong! Basically, the transmitted sound from client to the sever is awfully distorted and full of static sound! Is this normal behavior? I don't think it is otherwise it makes the solution completely unusable. So, what am I doing wrong to get this result? Furthermore, I eliminated as many parts as possible between the sever and client where I used only one USB sound card that is connected to the PiKVM and used 3.5 sound/mic splitter (which I tested it worked flawlessly when connected to external speaker), but yet the sound is awful and cannot be heard due to the background static. As a workaround, I connected the USB sound card to a windows machine and ran Jack/JackTrip to transmit just the sound to another windows machine in the same LAN but the result is still the same! Any thoughts from you or anyone in this forum is highly appreciated.

I'm getting the same issue. @josephum have you found a solution? I had to uninstall jacktrip to get sound back to my pikvm through HDMI, but now I can't use jacktrip.

Try to uninstall all the jack/jacktrip packages first: pacman -Rscnd jack2 jacktrip njconnect jack-example-tools

Then go to package cache to rollback with the packages that worked before: cd /var/cache/pacman/pkg/ pacman -U file:///rtaudio-5.2.0-2-armv7h.pkg.tar.xz pacman -U file:///xdg-utils-1.1.3+45+g301a1a4-1-any.pkg.tar.xz pacman -U file:///jacktrip-1:1.9.0-1-armv7h.pkg.tar.xz pacman -U file:///jack2-1.9.22-1-armv7h.pkg.tar.xz pacman -U file:///njconnect-1.6-3-armv7h.pkg.tar.xz pacman -U file:///jack-example-tools-4-1-armv7h.pkg.tar.xz

Works here!

Thank you, this seemed to solve my issue!

Note: There was an issue installing the jacktrip package, so I had to dig into this archive you provided: http://tardis.tiny-vps.com/aarm/repos/2023/11/01/armv7h/extra/ and manually installed all the dependencies it needed before I could successfully install the older version of jacktrip. This process looked something like this:

1. Find a dependency that I'm missing:
wget http://tardis.tiny-vps.com/aarm/repos/2023/11/01/armv7h/extra/qt5-base-5.15.11+kde+r138-1-armv7h.pkg.tar.xz
2. Install dependency after the download is complete:
sudo pacman -U qt5-base-5.15.11+kde+r138-1-armv7h.pkg.tar.xz

This can look entirely different for you depending on the dependencies it's asking you to install. Once I've installed all the dependencies (even the dependencies that my jacktrip dependencies needed)... I then attempted to reinstall the jacktrip package.

Appreciate you, @josephum for providing that archive.

I hope this helps someone else as well.

I did all of the above, services are enable and I have a connection from peer, I can also connect the inputs and outputs through qjackctl on my macbook.
BUT, I had zero sound coming through, neither in nor output.

I finally figured it out: With my PiKVM v4 I needed to set the AUDIO_DEVICE setting in the jack.conf:
AUDIO_DEVICE=-d hw:1,0 to AUDIO_DEVICE=-d hw:0,0 <-- 0,0 instead 1,0
