zdenko changed the title to problem with sound .

I presume this is not a Firefox only issue, but present in all sound related calls.
Log does not show any error for this.
Inxi output is a bit off though, both pipewire & pulseaudio are set to active:

Audio:
  Device-1: Intel Sunrise Point-LP HD Audio vendor: Lenovo ThinkPad X1 Carbon 5th Gen
    driver: snd_hda_intel v: kernel bus-ID: 00:1f.3
  API: ALSA v: k6.9.9-1 status: kernel-api
  Server-1: JACK v: 1.9.22 status: off
  Server-2: PipeWire v: 1.2.2 status: active
  Server-3: PulseAudio v: 17.0 status: active

server 3 should be off (and really should be using pipewire-pulse). What made you activate both?

Probably not related, but you have a ton of non-repo packages on your system (see the pacman -Qm output), seems none of those are self build, but are packages no longer in the KaOS repositories, you might want to clean those up.

Thanks a lot for your support, demm!
Yes, you are right with your assumption: it is present in all sound related
cases.

I actively did not turn on server 2 and 3. I only updated my system via
octopi from time to time.

In the meantime I cleaned up my packages: I used the cmd:
pacman -Qtdq | sudo pacman -Rns -
to remove orphaned unused packages, but unfortunately without success. My sound
problem still exists.

i have the same problem. No web browser play video on you tube. Start KDE sound is played. also goodvibes radio program from flatpak does not play sound.

inxi --audio
Audio:
Device-1: Intel 8 Series/C220 Series High Definition Audio

Device-2: NVIDIA GK208 HDMI/DP Audio driver: snd_hda_intel

Server-2: PulseAudio v: 17.0 status: active

Not clear if this is the same issue, OP had no issue playing video, just had to change sound-backend, then set it back to get sound (no answer if correcting not having both pipewire & pulseaudio active fixes the issue), so make sure to clarify, and post all the logs as done in the first post.

See the first post in this thread and https://kaosx.us/docs.
But please start a new topic if you have no video loading at all, and no way to get sound working, even after switching as explained in the first post. Then your issue is not related to this thread.

If you have video loading (still no answer to that), but no sound, then it could be the same issue, since you also have set to activate both pulseaudio & pipewire. This cannot be resolved by KaOS, that is a a setting you need to correct on your system.
And the same counts as for the OP, on a rolling system packages are removed/replaced over the years,it is important to keep your system clean from complete obsolete/unmaintained packages (see your log, starting at line 242).
https://kaosx.us/docs/pacman/#list-installed-packages-that-are-not-in-the-official-repositories

its maybe kde error - i have to switch bitween analog dupleks stereo and analog stereo output every login. Now i know how it be resolved. But is annoying to go to the kde sound settings and switch the te right output.

My youtube video (audio and video of a youtube piece and all os sound related things) do not start until I make use of the workaround. And the workaround does not last, I have to do it again and again in a session.

And again, did you adjust to run only one sound server? For both of you, I have asked many times now, you need to adjust your system to either use pipewire or pulseaudio. Those are user determined settings, not set by Plasma or KaOS. For KaOS, pipewire is default (during first install) and disabling pulseaudio, but that can ONLY be set as default during a first install, after that, it is a user choice.

How can I delete/deactivate my pulseaudio sound server? I never adjusted or changed anything of the standard sound configuration. My system must/could have done this on its own.

Best first check how you're system runs audio:
first: pactl info it will tell you how pulseaudio is used (through pipewire or not)
next, check user activated audio:
systemctl --user status wireplumber
systemctl --user status pipewire
systemctl --user status pulseaudio
Then see if pulseaudio runs system-wide:
sudo systemctl status pulseaudio

Thank you very much for your help.

systemctl --user status pulseaudio

○ pulseaudio.service - Sound Service
     Loaded: loaded (/usr/lib/systemd/user/pulseaudio.service; disabled; preset: enabled)
     Active: inactive (dead)
TriggeredBy: ○ pulseaudio.socket

sudo systemctl status pulseaudio 

Passwort: 
Unit pulseaudio.service could not be found.

I can't make heads or tails of all these data. Constantius24, do you know how to proceed?

I'm not an expert on this put it looks like both pipewire and pulseaudio are b0rked.
Your 'pactl info' results doesn't show what pulseaudio is running on. Mine has:
'Server Name: PulseAudio (on PipeWire 1.2.3)'

The output of your 'systemctl --user status pipewire' has on the second line pipewire.service disabled. Mine has:
'Loaded: loaded (/usr/lib/systemd/user/pipewire.service; enabled; preset: enabled)'

My suggestion would be that you reconfigure your sound to use pipewire exclusively.

pactl outcome shows pulseaudio is in use, but wireplumber is running.
So make a decision, do you want to stick with pulseaudio? then run:

systemctl --global disable pipewire
systemctl --global disable pipewire-pulse
systemctl --global disable wireplumber

The first 2 are probably not needed, looks like you only have wireplumber enabled, not pipewire.

If you want to move to pipewire (which was not available as install option when you installed KaOS in 2021), make sure all the above are set to enabled.

systemctl --user enable pipewire
systemctl --user enable pipewire-pulse
systemctl --user enable wireplumber

After reboot, pactl should show running on pipewire only (enabling pipewire will disable pulseaudio in normal installs).

Excellent. It is running. Thank you very much!
