I have no audio device after installing latest Win 11 update.

Hi, I'm Bernard. I'm happy to help!

To confirm, are you using a laptop or a desktop? Do you see an X mark on the audio icon on your taskbar? While waiting, I recommend running the audio troubleshooter, and if the issue persists, the next option is to roll back the audio driver. Kindly follow the steps below:

Method 1. Run the Audio troubleshooter:

Press the Windows Key + R, then type in:

msdt.exe /id AudioPlaybackDiagnostic

Then hit OK and follow the prompt to run the Audio troubleshooter.

Method 2. Roll back the audio driver:

-Press the Windows key + X

-Go to Device Manager

-Expand Sound, video and game controllers

-Look for Realtek (R) Audio or High Definition Audio

-Right-click and click Update Driver

-Select Browse my computer for drivers

-Click Let me pick from a list of available drivers on my computer

-Choose an old driver or another driver name, then select it and click Next until it installs.

-Restart the PC and check.

Note: If the issue persists, please download and install the audio driver from your manufacturer’s website.
