Troubleshoot audio issues in Windows 11 24H2 No audio Realtek Dell 8940 Reinstalled recent Driver 6.0.9486.1, A55

For now, until Microsoft figures out a fix, go to "Device Manager", expand "Sound, video, game controllers", right click on "Realtek(R) Audio" and select "Update driver", select "Browse my computer for drivers", select "Let me pick from a list of available drivers on my computer" and click "Next", select "High Definition Audio Device" and click "Next", you will get a popup window that states "Update Driver Warning", choose "Yes" to continue to install this driver, new "Update Drivers - Realtek(R) Audio" window will popup stating "Windows has successfully updated your drivers". Select "Close".

In "Device Manager" expand "Sound, video, game controllers", right click on "Realtek(R) Audio" and select "Properties", a new window will pop up "Realtek Audio Properties", "Driver Date" should read "7/3/2024", and "Drive Version" should read "10.0.26100.1150".

This should restore sound, but it is limited in functionality. Microsoft needs to be aware that not all Windows 11 approved systems use USB-based sound devices. They still need to fix the drivers ASAP to properly support motherboard-based 3.5mm jack analog outputs.

Soundless Windows 11 PCs are basically useless in today's streaming Internet world.

Dear GEStJoe!

Welcome to the Microsoft Community!

Windows 11 Insider Preview is positioned as a preview version (early testing) rather than a production version. Your problem is that after updating the Preview version of 24H2, the audio device does not work properly. I also noticed that many users clicked the same problem as you, but this may be due to the compatibility of the driver and the system version.

So, the solution is

Send feedback to Microsoft with the Feedback Hub app - Microsoft Support

you will send feedback and report to Microsoft.

What is the Windows Insider Program?

The Windows Insider Program is a community of millions of Windows fans

Be the first to learn about new features in Windows.

Windows Insider members can run platform preview versions called Windows Insider Preview versions.

You can check out new features.

During the Windows Preview period, Insider members can provide feedback and interact directly with Microsoft engineers so that known issues reported by users can be resolved after the next update is released.

Thank you for your understanding and support!
