## Description

**Audio Output Selector** is a Chrome extension that lets you seamlessly change the audio output device for HTML `<audio>` and `<video>` elements. Whether you want Twitch audio on your speakers and YouTube on your headset simultaneously, this extension makes managing multiple devices simple and flexible.

Please note, this add-on relies on the experimental Audio Output Devices API, which requires enabling `media.setsinkid.enabled` to `true` in `about:config`. While currently it updates audio devices only for existing elements when run, future updates aim to better support dynamic content on social media platforms. Open-source and community supported, you can find the project on [GitHub](https://github.com/AgentOink/audioOutputSelector).

## Review summary

Users praise Audio Output Selector for letting you pick the audio output (monitor vs speakers), its simple install with no permissions, and cross-platform open-source design. It’s seen as filling a Firefox gap and is widely appreciated. However, reliability problems exist: it’s not always consistent, may reset after video refreshes or output changes, and newer Firefox versions can break it. Linux users may need PulseAudio due to ALSA limits. A restart after config and minor UI quirks are noted. Overall, highly useful but not consistently dependable.

### Pros

- Core feature to select and route the audio output to the desired device (e.g., monitor vs main speakers).
- Easy to install with no permissions required.
- Cross-platform and open source (GitHub) with a simple, unobtrusive UI.
- Lightweight and doesn’t clutter Firefox; straightforward to use.
- Valued as a practical workaround for a missing built-in Firefox capability.

### Cons

- Unreliable at times; not 100% consistent across sessions.
- Compatibility issues with newer Firefox versions (sometimes not showing up or breaking).
- Linux users may need PulseAudio; ALSA-only setups can yield NotFoundError.
- Settings may reset after video refresh or output change, requiring re-selection.
- Restarting Firefox after configuration is often required for changes to take effect.
