[solved] Sound Dummy Output in pavucontrol

[Pirmin]

I lost my audio playback devices. In pavucontrol I don't see a sound output device. Neither integrated speakers nor HDMI output. When I start mpv I see the following lines:

Code: [Select]

ALSA lib pcm_pulse.c:758:(pulse_prepare) PulseAudio: Unable to create stream: Zeitüberschreitung
[ao/alsa] Unable to set hw-parameters: Eingabe-/Ausgabefehler
[ao/alsa] Attempting to work around even more ALSA bugs...

My sound cards are available:

Code: [Select]

cat /proc/asound/cards
 0 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xf7a14000 irq 38
 1 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf7a10000 irq 37

  Sound Server-2: PipeWire v: 0.3.48 running: yes

To fix this I had to install wireplumber, pipewire-audio-client-libraries and pipewire-media-session. The information is from Debian wiki:

Code: [Select]

sudo apt install pipewire-media-session wireplumber pipewire-audio-client-libraries

Reboot...

Just so pulseaudio users understand:

Code: [Select]

sudo apt rdepends pipewire-pulse
[sudo] password for user:
pipewire-pulse
Reverse Depends:
  Breaks: pipewire-media-session (<< 0.3.39-1)
  Recommends: wireplumber
  Depends: plasma-pa
  Replaces: pipewire-media-session (<< 0.3.39-1)
  Depends: libcanberra-pulse
  Depends: pavucontrol-qt
  Depends: phosh-core
  Depends: gnome-core

I had this issue again. Now I have to use wireplumber without pipewire-media-session.

Code: [Select]

sudo apt rdepends wireplumber

It crashes / collides with pipewire-media-session. Removing pipewire-media-session and installing wireplumber solves my problem and enables speaker output.
