"dummy AVRCP player" breaks GNOME's handling of play/pause button. Sometimes

  • PipeWire version (pipewire --version): 0.3.40
  • Distribution and distribution version (PRETTY_NAME from /etc/os-release): Fedora Linux 35 (Workstation Edition)
  • Desktop Environment: GNOME
  • Kernel version (uname -r): 5.14.18-300.fc35.x86_64

Description of Problem:

The introduction of "dummy AVRCP player" in 4b831021 enabled by default breaks play/pause button in GNOME desktop.

Actual Results:

When I am playing music or video, play/pause button in my headphones always works. However, when the playback is paused only 50% times the play/pause button of my headphones works. It's not completely random each time. Instead, "unpausing" works correctly for some time and after some time it does not work.

Expected Results:

I don't have to create this file to make play/pause button of my headphones working always:

[tomasz@gasior ~]$ cat ~/.config/wireplumber/bluetooth.lua.d/50-bluez-config.lua 
bluez_monitor.properties = {
    ["bluez5.dummy-avrcp-player"] = false,
}

**Update ** This is proper syntax for wireplumber 0.4.10: wireplumber#282 (closed)

[tomasz@gasior ~]$ cat ~/.config/wireplumber/bluetooth.lua.d/51-bluez-config.lua 
bluez_monitor.properties["bluez5.dummy-avrcp-player"] = false

Additional Info (as attachments):

To debug this problem I use preview window for setting custom keyboard shortcut in GNOME Control Center (Settings). screenshot This little window shows name of pressed button.

With bluez5.dummy-avrcp-player disabled when I press play/pause button in my headphones always "audio play" button is pressed which by default in GNOME is assigned to play/pause toggle-type action.

With bluez5.dummy-avrcp-player enabled (which is default) when I press play/pause button in my headphones:

  • when audio is playing "audio play" button is pressed which in GNOME is assigned to play/pause toggle-type action;
  • when audio is not playing:
    • sometimes "audio pause" button is pressed which in GNOME is assigned to pause action,
    • sometimes "audio play" button is pressed which in GNOME is assigned to play/pause toggle-type action.
