Lockscreen Audio Guard

Stops browser audio when the computer locks and prevents lock-screen media controls from resuming sound.

Lockscreen Audio Guard watches for the computer lock state and immediately controls browser audio across open tabs. It mutes tabs while locked, pauses audio and video elements where script control is allowed, and blocks new page playback until the browser reports the active state again. The extension is intended for Windows users who do not want Chrome or Edge media controls on the lock screen to resume browser audio before the computer is unlocked. It has no popup, options page, or user configuration. Loading the extension enables the behavior immediately.
