Thank you! Problem solved. :sunglasses:

How exactly?
Which one did you install (manjaro-pipewire would be my guess)?

I’ve got manjaro-pulse on my kde machine and still see those 2 sound servers as enabled in inxi output (probably due to pipewire being a dependency of kwin and manjaro-kde-settings).
Doesn’t cause any problems though.

Yes, i just installed manjaro-pipewire. When i was installing manjaro-pipewire it asked me some question about manjaro-pulse i sad yes on every one of them. Now everything work when i run inxi -Fxxz i get:

Sound Server-3: PulseAudio v: 15.0 running: no
  Sound Server-4: PipeWire v: 0.3.40 running: yes

Thanks for clarifying: essentially the switch from pulseaudio to pipewire fixed your issue.
