Audio and video out of sync on Hp Spectre x360

[Falling-Leaf]

Been having audio/video getting out of sync issues with my new Spectre x360. On Netflix, YouTubeTV, Hulu, Disney+ and CBS All Access, whether in Chrome, Firefox or Edge (YouTubeTV doesn't run in Edge) the video and audio will start out being in sync but after about 15-30 minutes, the audio will start to get in front of the video. The same issue happens in Zoom video conference! It happens when using the built-in display and happens when it's plugged into a monitor or TV with HDMI. 

There are many threads on the HP Community and the internet that I scoured and I have tried all the fixes (I've reinstalled audio and video drivers, changed audio driver to Microsoft, etc.) but nothing works.

I finally just reformatted to factory install and the issue persists. Help me please.

Welcome to the HP support community.

Is this issue specific to online content only or offline as well?

Meanwhile:

Run an Extensive system test to check for hardware failures.

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

3. On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.

4. Click Extensive Test.

5. Click Run once, or Loop until error. While the test is running, the time remaining and test result for each component are shown on the screen.

Let me know how it goes.

To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.

Cheers.
