no audio after update windows 11

Hi Małgorzata Krukowska,

You might navigate to your motherboard or laptop support page to check if a new updated audio driver is available, then download and install it. Some machines need updated driver to be compatible with new KB.

In case the manufactural does not release a new driver yet, you may uninstall the latest update following this article: How to uninstall a Windows Update.

If you have any further information, please feel free to let me know.

If you have trouble in any steps, I'm always here to help.

I hope that above suggestions are helpful to you.

Hi! Let me help you with this issue.

Please hover your mouse over the sound icon in the lower-right corner, then right-click it and select Troubleshoot Sound. Let the troubleshooter finish its task, then this should either resolve the problem or display an error message.

If that doesn't work, we need to remove the Audio driver from the Device Manager and restart the PC to reinstall it.

Here are the steps to completely remove a Device from your computer.

Step 1. Use the Windows key + X shortcut.

Step 2. Select Device Manager.

Step 3. Expand the entry Sound, Video, and Game Controllers. Right-click the problematic device, which is either Realtek Audio, or AMD High-definition Audio, or High-Definition Audio, depending on the audio device installed in your PC, and select Uninstall device.

Step 4. You need to check the option Delete the driver software for this device and then click the Uninstall button.

Step 5. Reboot the computer.

After the reboot, please see if the problem is fixed.

If that still does not work, please visit the support website of your laptop or desktop and then download and install the latest Audio driver, then restart the PC.

Follow these steps in order on Windows 11 after the update:

1. Run the Windows audio troubleshooter
   • Open the Get Help app using the "Run the troubleshooter in Get Help" link from the audio article, or search for Get Help and run the audio troubleshooter.
   • Let it detect and fix common sound problems.
2. Check the output device
   • Select the Speakers icon on the taskbar.
   • Select the arrow to the right of the volume slider (tooltip: Select a sound output).
   • Choose the correct device (e.g., speakers, headphones) and test audio again.
3. Restart to apply pending updates
   • Save work and close apps.
   • Select Start > Power.
   • If shown, choose Update and restart (or Update and shut down) to complete any audio‑related updates.
4. Update the Realtek audio driver
   • In the taskbar search box, type device manager and open it.
   • Expand Sound, video and game controllers.
   • Right‑click the Realtek (or other) audio device > Update driver > Search automatically for drivers and complete the wizard.
   • If no newer driver is found, download and install the latest audio driver from the PC or motherboard manufacturer’s support site.
5. Reinstall the audio driver
   • In Device Manager > Sound, video and game controllers, right‑click the Realtek (or current) audio device.
   • Select Uninstall device.
   • Check Attempt to remove the driver for this device.
   • Select Uninstall.
   • Restart the PC (this will reinstall an audio driver automatically).
6. Try the generic Windows audio driver
   • In Device Manager, right‑click the audio device > Update driver.
   • Select Browse my computer for drivers > Let me pick from a list of available drivers on my computer.
   • Select the generic High Definition Audio device (or similar), click Next, and complete installation.
7. If audio broke right after the update, roll back the driver
   • In Device Manager > Sound, video and game controllers, right‑click the Realtek (or affected) device > Properties.
   • Go to the Driver tab and select Roll Back Driver.
   • Follow the prompts and confirm.

If none of these steps restore sound, use a system restore point created before the update (see "Restore from a system restore point" in the Recovery options article linked from the audio troubleshooting page).
