Part 1. Why My YouTube Audio Not in Sync with Video

The problem of YouTube audio not in sync with video is relatively common. Many users have encountered similar situations. Based on the actual test and your feedback, we have summarized a few points with the highest probability of triggers. You can check according to the following items to see if any of them match your situation.

There is an error in the video itself

First, you can try playing other content on the YouTube platform to see if there is a similar issue. If the other videos are working fine, there is an error in the current video. This could be caused by a problem with the creator's editing or a bug in the platform when uploading the video.

Problems with the YouTube platform

If you're using an older version of YouTube, you may be experiencing glitches, such as YouTube audio being out of sync. It is also possible that YouTube is currently running laggy.

There is a delay in your network

If the network you are connecting to when you play a video has a slow or unstable internet connection, then it may cause the online content not to be loaded properly. At this time, there is a high probability of YouTube sound out of sync problems.

You are connected to a Bluetooth device

When you use Bluetooth to transmit data, you may experience signal delay. This problem is especially noticeable with Bluetooth headphones and speakers. Therefore, if you are currently listening to the sound of a video from YouTube via a Bluetooth device, you may experience a YouTube audio sync problem.

Your device is lagging

If your device has too many apps running in the background, it is likely to lag and cause YouTube audio delay. Another trigger is that you have too much cache of YouTube software on your device, which prevents it from working smoothly.

Different solutions for different devices. Let's start with cell phones.

Restart Your Phone

Restarting your phone is the fastest solution if it's a temporary error or malfunction of your YouTube app or device. This method also applies to tablets.

Clear YouTube's Cache

We have already mentioned that too much YouTube cache can lead to lag and audio/video delay. You can force-close the YouTube app before clearing the cache. Let's take an Android phone as an example.

Step 1. Close the YouTube app. Open Settings on your desktop.

Step 2. Choose Manage Apps, and select YouTube from the menu.

Step 3. Tap Clear Data > Clear Cache. Open YouTube and try to play the video again when it is over.

Tips: If a reboot doesn't solve the problem, check if you need to update your existing YouTube app.

If the problem persists, uninstall the app and download a new one from the app store.

Adjusting Bluetooth Devices

You can try placing a Bluetooth headset or device close to your phone. Doing so will ensure that your device is in low latency mode. Try disconnecting the Bluetooth connection and playing the video using your phone's speakers.

Change Your Internet Connection

You can try changing to a more stable WiFi connection or turning on your phone's data network. Then, replay the video. This solution also solves the problem of videos not playing on iPhone.
