Bilibili Auto Suspend Audio

Automatically suspends audio context on Bilibili pages when the system is locked and nothing is playing.

This extension is designed to address a situation where Bilibili pages may continue occupying the audio pipeline even after media playback is paused, which can prevent USB DACs, headphones, and other audio devices from entering normal standby or sleep states. Once enabled, the extension works only on bilibili.com pages and manages the page audio context based on the following conditions: - When the system is locked and no audio or video is currently playing, it automatically suspends the page’s audio context - When the system is unlocked and media playback resumes, it restores the audio context automatically - The extension does not forcibly pause videos and does not alter your playback progress - It runs only on Bilibili pages and does not affect other websites This extension is intended for users who want to reduce unnecessary audio-device occupation caused by Bilibili pages and improve standby behavior for external audio hardware.
