YouTube Audio/Video Sync

Fix wireless audio streaming delay for YouTube

What is YouTube Audio/Video Sync?

"YouTube Audio/Video Sync" is a Chrome Extension which helps to balance the audio-video delay experienced while streaming YouTube content to wireless devices. It's efficient for any video that seems out of sync, enables manual delay adjustment, and offers an auto-toggle option for when the audio device is connected. The lip sync struggle can also be kept under control with specified settings. However, it does not support YouTube Live Videos and only works on youtube.com.

Summary

Analyze keywords

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 Chrome Extension attempts to solve this problem for YouTube.

The extension allows adjusting to a positive delay as well as a negative one making it possible also to correct any YouTube video that has been uploaded out of sync.

One time set up:

Go to options
Click on "Find your system's delay"
A sound will be played, listen and press the button when you hear the last beep
The approximate delay will be filled in "Global Audio Delay (ms)"
Play a YouTube video and check if you are satisfied with the sync. If it is not perfectly in sync, repeat the steps above or adjust the delay value manually and save. You can do this from the Options page or directly from the YouTube player
You can enable/disable the sync adjustment from the YouTube player or by clicking on the extension's icon in the toolbar.

Additional features:

Auto toggle extension when audio device is connected
The selectable delay value is limited to 5000ms in either direction but you can change this when you go to More Options: Maximum Selectable Delay (ms)

I have an old school Home Theater PC with HDMI to TV--> optical out to a Denon receiver. Over just Youtube I get an audio delay which I was unable to get rid of. It was worst in Firefox and a bit better in Edge, but still there. I just found this plug-in for Chrome and it absolutely works, my audio/video are in perfect synch now. The + and - slider makes this a winner.

I'm connected to bluetooth speakers with quite the delay, I was scared that the extension only allows audio delay.. but after adding, I found that this extension also allows video delay (meaning - delay in audio) and this was absolutely perform for my case. Thank you for this extension!

This was a fantastic extension, which worked for the most part flawlessly, however very recently - due possibly to updates in Chrome or changes in YouTube - it no longer works. I have tried posting in the support the section, along with many other previously satisfied users, alas the author has not even acknowledged these posts. I was so impressed with the extension that I "bought the author a coffee". However I feel that a one star rating is now justified. This will be changed to a 5 star when the author tries to fix the extension or even says he is aware of the problem and will attempt maintenance in the near future. Thank you so much Adrian, working perfectly again! ❤
