Main Causes of Audio and Video Desynchronization

Audio and video desynchronization when watching YouTube on your new laptop can be caused by several factors:

1. Browser hardware acceleration - one of the most common causes. As noted in research on synchronization issues, hardware acceleration can cause delays in processing audio and video streams.

2. Outdated device drivers - on new laptops, it’s important to promptly update audio card and graphics processor drivers. According to this source, outdated software for audio cards or GPUs often leads to synchronization problems.

3. Codec conflicts - as mentioned in one guide, having extra or incorrect codec packs can disrupt proper media stream processing.

4. Browser or extension issues - browser cache, corrupted files, or conflicting extensions can cause desynchronization.

5. System settings - power saving or performance parameters can affect multimedia processing.

Diagnosis and Additional Information

Checking on Other Devices

To determine if the problem is related to your laptop, try watching the same videos on another device. If the issue only occurs on your laptop, it indicates a system-related cause.

Monitoring System Resources

Use Task Manager to monitor CPU and memory usage while watching videos. High resource usage can cause delays in audio and video processing.

Updating Windows and Browsers

Ensure you have the latest updates for Windows and all browsers you use. As indicated in sources, outdated software often causes synchronization problems.

Contacting Support

If none of the solutions work, contact YouTube support or your laptop manufacturer for additional assistance.
