Issues with Media keys

[alkaris2]

Introduction
I recently switched over to Manjaro KDE Plasma, and I've come to find this driver doesn't seem to respond to media control inputs just like when I was using Manjaro Cinnamon. The Roccat Vulcan 121 with it's media keys and dial knob for volume control and LED brightness adjustment doesn't appear to work, at least the volume part anyway, switching to FX mode I can change the the LED brightness, but when it's on Volume control it doesn't appear to be do anything except for light up half the keyboard to show volume level.

Please describe the bug
Not too sure if this is KDE bug or driver bug. But media keys and knob dial doesn't function, media keys for Stop and Pause/Play only seems to work when a video or music is being played, but it'll only let you use the volume controls when something is in use, but you can't change volume with the knob dial even though it shows the volume level when you turn it.

To Reproduce
Just using Manjaro KDE Plasma

Expected behavior
Was just hoping and expecting the media keys to continue to function after installing Eruption. The system does seem to register inputs for media control, but no idea how to map them to the media controls.

Logs

Have you tried to reinstall eruption?

it's literally the same result every time. So no.

Thank you for the speedy reply. It seems like we are in the same time zone! 😄
It seems like Manjaro KDE has different drivers than Manjaro Cinnamon. They can have different drivers. Heres what I suggest you do:

-- Install the following packages:

sudo pacman -Sy libevdev hidapi systemd-libs dbus libpulse lua lua-socket gtksourceview4
sudo pacman -Sy gcc pkgconf make cmake protobuf xorg-server-devel libxrandr gtk3

Also ensure that you have git and rust. MSRV 1.64, see install.MD for more details

Please also report to me if Eruption GUI Works.

PLEASE NOTE THAT THIS MAY NOT BE A ERUPTION PROBLEM. DIFFERENT DESKTOPS HAVE DIFFERENT DRIVERS!
If I am unable to fix your awnser, I recommend posting to r/linux (if no one replies.) Thank You!

Thank you!

I ran into a similar issue and found this thread looking for an answer. I thought my issue was the same as OP here as I'm also using KDE Plasma on an Arch-based system (Garuda) and the exact same keyboard.

It turned out that my keyboard had outdated firmware. Running 'sudo journalctl -u eruption.service' I found this message:

Jun 06 18:58:32 elysium eruption[253579]: elysium eruption[253579]: Outdated firmware version: 1.31, should be: >= 1.36

As per a comment by @X3n0m0rph59 on a similar issue from a few years ago ( found here: #79 (comment) ) I used a Windows computer to install the Swarm software from here (check the list of supported products for each to see which you need for your keyboard):

Swarm I: https://support.turtlebeach.com/s/downloads?language=en_US#/76/Roccat/ROCCAT-Swarm
Swarm II: https://support.turtlebeach.com/s/downloads?language=en_US#/319/Swarm-II

I accidentally downloaded Swarm II first and it auto-detected that it was the wrong version and automatically downloaded Swarm I.

From there you'll be able to update your firmware. Then, as soon as I plugged the keyboard back into my Linux system everything worked as expected.

This doesn't appear to be the OPs issue, as their linked eruption-service.log file doesn't seem to indicate outdated firmware. I'm just posting this comment in case anyone else finds this issue looking for a fix and wants to try this.

For further context, in case it helps anyone: I had installed the eruption package via Paru and Garuda automatically routed the install through their chaotic-AUR repo, which I believe just pulls from the standard AUR. Previous to discovering my firmware issue, I also applied the suggested fix by @cooldudeseven7Dev in the previous comment here and made sure to run the following commands to enable all the services in systemctl (from the install documentation):

systemctl --user enable --now eruption-fx-proxy.service
systemctl --user enable --now eruption-audio-proxy.service
systemctl --user enable --now eruption-process-monitor.service

sudo systemctl enable --now eruption.service

I hope this helps someone!
