Audio Output Selector — AgentOink

Allows you to change the audio output device of <audio> and <video> elements.

Do you have multiple audio output devices? Do you like to switch between using your TV and your headset? The aim with this extension is to not only make this process easier, but more flexible. Now you can have Twitch open in one tab, playing on your speakers, and YouTube in another, playing to your headset.

IMPORTANT INFORMATION: This add-on makes use of an experimental feature called "The Audio Output Devices API" . This feature is disabled by default. Please enable it by setting media.setsinkid.enabled to true in about:config.

I 💜 open-source! Check out the GitHub?

NOTE: Currently the extension only updates elements on the page when it is run. This means new elements will not use the selected audio device without rerunning the script. This is a problem for social media sites, such as Twitter and Reddit. I'll look into supporting this behaviour in future.
