Audio/Video Sync Issue on Lenovo Yoga Pro 9 16IMH9

system summary.LOGHi Microsoft Support Team!

I hope you can help me with an issue I’ve been experiencing on my new Lenovo laptop. Since I received it three months ago, whenever I watch videos — whether in browsers (Chrome, Firefox, Edge, Opera) or in-game cut-scenes (e.g. Call of Duty) — the audio drifts ahead of the video after about 7–10 minutes. Refreshing the page temporarily fixes it, but it recurs shortly thereafter. However, in Media Player, I don’t think I’ve seen the problem occur. 

  1. A few things I’ve tried so far

Disabled hardware acceleration in each browser (video quality tears a bit and the problem persists after about 5 minutes).

Switched graphics settings between Integrated GPU, NVIDIA GPU only, and “Auto-select” in NVIDIA control panel settings.

Tested with external Bose speakers and the built-in speakers, toggling hardware acceleration for the Bluetooth speaker and also under Windows Settings > Graphics

Verified the issue occurs across all playback sources (browsers, games, media player).

Clean Windows Install

Re-install the audio drivers, motherboard drivers, and Bluetooth drivers from the Lenovo website

  1. My System Configuration (as of 02 Aug 2025):

I attached a System Summary linked in a text file from HWiNFO

Computer Model: Lenovo Yoga Pro 9 16IMH9

Operating System: Microsoft Windows 11 Home (x64) Build 26100.4652 (24H2)

Processor: Intel Core Ultra 9 185H (16 cores, 22 threads)

Graphics: Intel Arc Graphics “Meteor Lake-P” Integrated (15 GB VRAM; Driver v32.0.101.5763, 14-Jul-2024)

Memory: 32 GB LPDDR5 @ 7467 MT/s (4 × 8 GB Samsung modules)

Audio Adapter: Intel Meteor Lake-U/H PCH – cAVS (RealTek codec; Smart Sound Tech BUS Driver v20.40.11112.7, 31-Jul-2024)

BIOS: Version NKCN31WW (03 Mar 2025)

  1. Next Steps / Questions:

Are there known issues with the RealTek audio driver or Intel Arc / Meteor Lake graphics in this Windows build that could cause AV desync?

Should I try rolling back to an earlier audio or GPU driver version? If so, which one?

Is there a recommended fix or hotfix I can apply via Windows Update or a standalone installer?

Thank you for your assistance. Please let me know if you need any further logs or configuration details.

    Hi Max, Thanks for sharing all those details. Let’s walk through some steps together to see if we can get things back on track. I’ll break this down into simple steps.

    Here’s what I recommend:

    1.Check for updates - sometimes the latest updates solve these kinds of problems behind the scenes

    • Press Windows + I to open Settings
    • Go to Windows Update > click Check for updates
    • Install everything listed, including anything under "Optional updates"

    Next, open the Lenovo Vantage app:

    • Go to System update
    • Install any updates it suggest (BIOS, drivers, etc.)

    2.Try Rolling Back Your Drivers - sometimes a new driver can cause weird issues. Going back to an older version might help

    For your audio driver:

    • Right-click the Start button > choose Device Manager
    • Open Sound, video and game controllers
    • Right-click the audio device > Properties > go to the Driver tab
    • If "Roll Back Driver" is active, click it
    • If not, uninstall the driver, then download and install an older version from Lenovo's website (try a version before July 2024)

    For your graphics driver:

    • Do the same under Display adapters (for your Intel Arc graphics)
    • Try using a version from May or June 2024

    P. S. Don't forget to restart your laptop after changing drivers.

    3.Turn off Audio Enhancements - sound enhancements can sometimes cause problems with syncing.

    • Right-click the speaker icon on your taskbar > click Sound settings
    • Scroll down to Advanced > click All sound devices
    • Choose your speaker > turn off any sound effects or enhancements

    4.Try a different user account - just to see if something in your profile is causing the issue

    • Go to Settings > Accounts > Family & other users
    • Create a new user
    • Log in as the new user and test the video again

    Let me know how it goes. If you still doesn't fix it, I'm just here to help.
