Notification Sound

Overview: Adds audible feedback to Odoo backend notifications so operators are alerted instantly without watching the screen.

Features:

• Plays different sounds depending on notification type:
  • Success → notify.wav
  • Warning → exclamation.wav
  • Error (danger) → error.wav
  • Info → bell.wav
• Seamless integration with the backend (no extra UI); patches the OWL component web.NotificationWowl.
• Assets are loaded via web.assets_backend (JS + XML + sounds).
• Per‑user toggle in Preferences: each user can enable/disable notification sounds from their profile.

How it works (technical):

• Frontend logic is handled in JS (static/src/js/notification_sound.js) by patching the Notification OWL component and using OWL hooks (onMounted, onWillUpdateProps) to play a sound when a notification appears/updates.
• The module reads the user preference via the Odoo RPC service:
  • const result = await rpc("/web/session/get_session_info");
  • The module caches the boolean result.user_context.notification_sound_enabled so only one RPC is performed per page load.
• Backend exposes the preference through:
  • new field res.users.notification_sound_enabled (default True)
  • ir.http.session_info() enriched to include the flag in user_context.
• Sound files live under static/src/sounds/ and can be replaced if desired.

Installation & Usage:

1. Install the module like any other addon.
2. Use Odoo normally; when a backend notification pops (success/warning/error/info), a short sound plays automatically.
3. To disable sounds for your account, open Settings → Users → Your user → Preferences and uncheck “Enable notification sounds”. Reload the page to refresh the session preference.

Compatibility:

• Odoo 18 (web backend).
• Modern desktop browsers. Note: Browser auto‑play policies may require at least one prior user interaction with the page before sounds can play.

Troubleshooting / Notes:

• If your browser blocks auto‑play, the first notification may be silent until you interact (click/keypress) on the page.
• After changing the preference, reload the page so the cached value and session info are refreshed.
• Mobile browsers may mute auto‑played audio by default.
