AuRo is a Chrome extension that allows users to select an audio output device for HTML5 audio and video elements. Developed by ISh-, this free extension falls under the category of Browsers and the subcategory of Add-ons & Tools.

AuRo version 0.3 introduces the ability to save the audio output device ID for the current tab domain. This feature provides users with a seamless experience by automatically switching to the desired audio output device when visiting websites that utilize HTML5 audio and video elements.

The extension works by patching the HTML5 audio and video .play() method, allowing users to manipulate the `sinkId` and select their preferred audio output device. It is important to note that AuRo does not support AudioContext, as the setSinkId() method is not implemented for it.

To avoid script injection on every page and minimize performance impact, AuRo may require pausing and playing media during initialization. This ensures that the extension functions properly without causing unnecessary overhead for users.

AuRo is a valuable tool for Chrome users who frequently utilize HTML5 audio and video elements and desire more control over their audio output device selection.
