Audio/Video Sync for YouTube is a Chrome extension designed to fix wireless audio streaming delays specifically for YouTube content. When streaming from your device to external receivers like Apple TV, AirPlay speakers, Sonos, and more, maintaining audio-video synchronization can be challenging. This tool allows users to adjust audio delays, both positive and negative, to ensure perfect alignment for videos that are out of sync.

To set up, users can easily find their system's delay by following a simple process within the options menu. The extension provides a user-friendly interface for adjusting delay values manually and saving them for future use directly from the YouTube player or the Options page. Additionally, the extension offers features like auto-toggle when a new audio device is connected and customizable delay settings to enhance the viewing experience.
