There is always a delay when streaming audio from your device to a receiver (Apple TV, AirPlay speakers, Sonos, Network Player, TuneBlade, Bluetooth, etc.). This is not a big issue when streaming music but any video will become out of sync. This addon attempts to solve this issue for YouTube.

One time set up:
- Play a YouTube video
- Go to the addon's Options
- Adjust the latency slider until the audio becomes in sync with the video
- You can disable the sync adjustment by clicking on the addon icon.

YouTube Audio/Video Sync works by muting the original video and reloading the audio adjusted to the selected delay.

Note:
-YouTube Live Videos are not supported.
-This extension (at least for now) will only work on youtube.com, embedded YouTube players on other websites will not work.
