Plugin sounds vianoctalia.sound.playare not affected byenable_soundsor the per-event toggles.- While
enable_soundsistrue, each per-event toggle gates one shell sound:enable_volume_sounds(volume changes),enable_notification_sounds(notifications),enable_power_sounds(charger connect or remove), andenable_screenshot_sounds(screenshots). The per-event toggles, the sound volume and the sound theme are hidden in Settings whileenable_soundsisfalse. sound_volumecontrols all UI sounds. A value of1.0plays the source at unity gain; lower values follow a perceptual volume curve. Files are decoded throughlibsndfile; common supported formats include WAV, FLAC, Ogg/Vorbis, Opus, MP3, and AIFF. Exact format support depends on the distribution’s libsndfile build.sound_themeselects an installed sound theme. Themes inherit from their declared parents and fall back tofreedesktop; shell sounds are loaded from each theme’sstereodirectory. Premade themes are available on Pling; install them under~/.local/share/sounds/<theme-name>/. To create your own, follow the freedesktop Sound Theme Specification.- Shell sounds use these theme events:
message-new-instant(notifications),audio-volume-change(volume changes),power-plug/power-unplug(laptop charger connected or removed), andscreen-capture(screenshots). If a theme lacks the exact event, its trailing dash components are stripped (e.g.message-new-instant, thenmessage-new, thenmessage) before trying parent themes. - Sounds play as a PipeWire stream with
media.role=Notification. WirePlumber shares one saved volume, mute state, and output device across all Notification-role streams, shown as “System Sounds” in pavucontrol, GNOME, and KDE. If shell sounds are silent while other audio works, see the FAQ entry.
Noctalia reconnects automatically if the PipeWire daemon restarts or is temporarily unavailable. Audio devices and controls disappear while the daemon is offline and repopulate after PipeWire and its session manager are ready again.
