[SOLVED] No output devices on KDE

jojo06 · 2024-06-18 17:18:15

I installed KDE on the laptop, I use pipewire. `Pipewire is mandatory for Wayland, for screen sharing etc.` In X11 the desktop is already broken. No background, no taskbar. I use it in Wayland, it also worked with lightdm but I installed sddm because it was healthier (recommended).

How do I solve the sound problem?
Is it wrong to use lightdm?

This sounds like few different problems.

1. Is the pipewire (+wireplumber) up and running? Do you run them as system or as the user?
2. Attach the log:

journalctl -b | curl -F 'file=@-' 0x0.st

jojo06 · 2024-06-19 23:28:45

I remember starting it with --user when I was trying to solve the problem, but I also tried with --system, I don't know which one it works with now.

You're not loading any audio related kernel module here, what laptop is this exactly? What do you get from

lspci -k
lsusb #Needs usbutils

check your BIOS whether the integrated sound card is disabled

Starting pipewire as a system service is almost always wrong, but you currently simply have no audio device on a kernel level, you need to fix that first.

In BIOS what i am gonna look exactly ?

impossibleveins23 · 2024-06-20 08:17:05

Check in the BIOS whether the option to disable onboard soundcard in on.
Following, lspci should show a row regarding audio device.

jojo06 · 2024-06-20 18:44:30

Yes, it was disabled in BIOS settings, I enabled it. Now there is sound, I tried it after reboot and it works.

How about `--system` or `--user` enabled situation ? How can i look did i start with which one and/or convert to `--user` ?

jl2 · 2024-06-20 20:04:31

--system is only used when you have multiple users that want to control the same output devices or headless devices/servers
you want to go with --user.

However, shouldn't pipewire/wireplumber's systemd service use the --user by default? I highly recommend to use systemd to manage them, simply because it is the default and I don't see any reason not to.

Why do users prefer --system --user then ? I thought that was the default. How can I change it to systemd ? And when I change it, the `--system --user` conf. will be disabled too, right ? I don't want to have problems in the future.

I would also like to ask why there are 2 different commands and why --user cannot be used when there is more than one user ? Or vice versa... What kind of problem can occur?

V1del · 2024-06-20 21:27:10

The main question here is who is allowed access to the sound device. In the vast majority of cases your current active user should get that which is why the --user service should be preferred. There are some things you'd have to be weary of for system wide services. But pipewire doesn't ship a system wide service by default, unless you actively messed with that this will be irrelevant.

--user can be used when there's more than one user, but the specific services are "per user" not "per system" so you'll have multiple instances depending on the user (which is what you'd normally want, otherwise random users can listen to what you're listening and vice versa) it's primarily about properly separating privileges.

for checking, what do the outputs of

systemctl --user status pipewire{,-pulse} wireplumber
systemctl status pipewire{,-pulse} wireplumber

give you?

If this is [SOLVED] please mark it as such by editing the title in your first post.
