Electron Notification API and Linux Desktop Environments: Controlling Alert Noise

Question

Goal
Developers want to suppress audible alerts from Electron notifications while still delivering visual cues, especially when the app runs across macOS, Windows, and various Linux desktop environments.
Constraints & Uncertainty
The silent flag in Electron’s Notification API is honored on macOS and Windows but is often ignored on many Linux DEs, and the badge property is only supported on macOS and Windows. The autoUpdater module triggers system‑level notifications that remain under the control of the OS, with no cross‑platform API to suppress them. An unresolved design decision is whether Electron should expose a unified muteAllNotifications flag that would silence all native notifications regardless of platform.
Open Questions

Should Electron provide a muteAllNotifications flag to suppress all native alerts, and how would this interact with user‑configured privacy settings?
What mechanisms can reliably silence notifications on Linux DEs that do not respect the silent flag?
How does powerSaveBlocker affect notification sound playback, and can it be leveraged to enforce silence?

Suppressing Notification Sounds in Electron
To suppress audible alerts while maintaining visual notifications in Electron, use the silent: true property within the Notification constructor. While this is natively honored on macOS and Windows, it is frequently ignored by Linux Desktop Environments (DEs) because Electron delegates notification handling to the system's notification daemon (typically via libnotify).

Platform Behavior and Limitations
The inconsistency on Linux stems from the fact that many DEs prioritize user-defined system settings over application-level requests. If a user has enabled notification sounds globally in GNOME, KDE, or XFCE, the silent flag may be overridden by the OS.

Platform
      silent: true Support
      Control Mechanism

macOS
      Consistent
      System Notification Center

Windows
      Consistent
      Action Center / Focus Assist

Linux
      Inconsistent
      DE Notification Daemon (libnotify)

Implementation Steps for Linux Noise Control
Since there is no cross-platform muteAllNotifications flag and the autoUpdater module triggers system-level alerts outside the app's API control, use these steps to manage noise on Linux:

Apply the API Flag: Always include silent: true in your notification options to ensure compatibility with Windows and macOS users.
  Verify System Overrides: If notifications remain audible on Linux, check the DE settings (e.g., Settings > Notifications in GNOME) to see if "Allow Sounds" is overriding application requests.
  Isolate the Daemon: Use the terminal to verify if the issue is with Electron or the OS. Run the following command to see if a native silent notification is possible on the current system:
    notify-send "Test" "This is a silent test" -u low

Technical Clarifications

powerSaveBlocker: This API manages system sleep and wake states. It has no architectural connection to the audio pipeline and cannot be used to silence notifications.
  Badge Property: The badge property is restricted to macOS and Windows and provides no mechanism for audio suppression on Linux.

Diagnostic Detail Needed: To provide a more specific workaround, please specify which Linux Desktop Environment (e.g., GNOME 45, KDE Plasma 6, XFCE) is being used, as the notification daemon implementation varies significantly between them.
