Extension Metadata
About this extension
Solo Sound keeps your browser quiet by ensuring only one tab plays audio at a time. When a tab starts playing sound or gets unmuted, all other audible tabs are automatically muted.
To avoid muting short notification sounds (Gmail, Slack, Discord, etc.), the extension includes a configurable debounce delay and a title whitelist. Tabs matching the whitelist are never muted and never trigger muting of other tabs. Regex patterns are supported.
Additional options include ignoring pinned tabs and auto-unmuting muted tabs when switching to them. All settings are configurable from the options page.
