## Description

## audioff - Audio Device Selector

audioff is a versatile Chrome extension that allows users to select specific audio output devices for each browser tab individually. It supports HTML5 `<audio>` and `<video>` elements, making it perfect for managing sound output when using multiple audio devices simultaneously.

The latest 2.1.0 update improves user privacy by injecting scripts only on pages when needed, instead of running on all sites. This minimizes permission requests and enhances security. The extension requires enabling `media.setsinkid` in Firefox for compatibility. For users concerned about permissions, audioff can also be used as a bookmarklet alternative. Full details and source code are available on [GitHub](https://github.com/chuang861012/audioff).

## Review summary

Overall, users like the ability to route a tab’s audio to a different device in a simple, maintained tool. It’s helpful for multi-device setups and basic use, with guidance for enabling the required Firefox setting. However, recurring issues reduce value: selections don’t persist across YouTube video or playlist changes, and settings aren’t saved between videos or sessions; site compatibility is uneven; and users must enable media.setsinkid.enabled via about:config. Privacy concerns are raised, and some report breakage after Firefox updates. Improvements are needed for persistence and broader compatibility.

### Pros

- Allows routing a tab's audio to a different output device (e.g., HDMI/TV or soundbar) for multi-device setups.
- Simple, clean, easy-to-use functionality.
- Works well for real-world multi-device use cases like livestreams and separate speakers.
- Maintained/updated with ongoing support; users appreciate ongoing maintenance.
- Offers clear guidance and a straightforward way to enable the required Firefox setting (about:config).

### Cons

- Selections do not persist across YouTube videos or playlist changes, requiring reselecting or refreshing.
- Settings and selections are not saved between videos or sessions.
- Compatibility is site-dependent; it only works on some sites.
- Requires enabling the about:config flag (media.setsinkid.enabled), which is non-intuitive.
- Privacy concerns: requests full access to data on all websites.
