YouTube video sound delay fix: In this article, we will outline the methods to try if you’re experiencing audio sync issues while watching YouTube videos. We hope these troubleshooting steps will help resolve the problem and provide you with a seamless viewing experience.

First Steps to Address YouTube Audio Sync Issues
Close Unwanted Tabs: Opening too many tabs on your browser while using YouTube can affect your internet speed and lead to issues. Try to keep only essential tabs open, ideally limiting them to 6-8 tabs.
Close Background Apps/Tabs: Close any open applications or background tabs that may be consuming system resources.
Restart Your Device: Rebooting your system or turning it off and on again can often resolve temporary software issues.
Disable VPN or Proxy: When using VPN or proxy services, they can continue to use system resources and internet bandwidth in the background, potentially hindering the proper buffering and playback of YouTube videos. Try disabling VPN or proxy services to troubleshoot the issue. If you’re not using a VPN, consider trying one to see if it improves the situation.
Clear Browsing Data: Accumulated cache, cookies, and browsing data in your browser can cause problems over time. Periodically clearing these data can help your browser run more smoothly and improve the playback of YouTube videos. You can clear these data from your browser’s settings.
Free Up RAM: Clearing your system’s RAM can enhance overall system performance. This, in turn, can help ensure smoother YouTube video playback. You can clear RAM through your operating system or browser settings.
Check for Browser Updates: Using the latest version of your browser can reduce YouTube-related issues. Check for updates in your browser’s settings and install the latest version.
Try Different Hardware: When encountering such issues on your computer, it’s worth trying external audio and display hardware.
Test Your Internet Connection: We strongly recommend connecting to different networks and testing. If you can’t access multiple wireless networks, consider sharing your phone’s internet and connecting your device to it for testing.
DNS Test: DNS issues can occasionally cause problems, and manually configuring DNS settings can provide a temporary solution.
