Follow these steps in Windows 11 to fix the “No audio device is installed” issue:
- Check that Windows sees an audio device
- Right-click Start and select Device Manager.
- Expand Sound, video and game controllers.
- If no audio device is listed, or it shows a warning icon, continue with driver steps below.
- Update the audio driver automatically
- In Device Manager, under Sound, video and game controllers, right-click the audio device (for example, Realtek, Intel, or your speaker/headset name).
- Select Update driver.
- Select Search automatically for drivers.
- Complete the wizard and then test sound.
- If Windows does not find a driver, download the latest audio driver from the PC or motherboard manufacturer’s support site and install it, then test again.
- Reinstall the audio driver
- In Device Manager, right-click the audio device under Sound, video and game controllers.
- Select Uninstall device.
- Check Attempt to remove the driver for this device and select Uninstall.
- Restart the PC (save all work first). Windows will attempt to reinstall the audio driver automatically.
- After restart, test sound.
- Use the generic Windows audio driver
- Open Device Manager again.
- Expand Sound, video and game controllers.
- Right-click the audio device and select Update driver.
- Select Browse my computer for drivers.
- Select Let me pick from a list of available drivers on my computer.
- Select the audio device driver shown, click Next, and follow the prompts.
- Test sound.
- If the problem started after a Windows Update
- Open Device Manager.
- Expand Sound, video and game controllers and right-click the audio device.
- Select Properties → Driver tab → Roll Back Driver.
- Follow the prompts and select Yes to roll back.
- Test sound.
- If roll back is not available or does not help, use a system restore point created before the problem started. See “Restore from a system restore point” in Recovery options in Windows (linked in the referenced article).
- Run the built-in audio troubleshooter
- Open Settings → System → Troubleshoot → Other troubleshooters.
- Run Playing Audio and apply any fixes it suggests.
If Device Manager shows no audio device at all even after reinstalling drivers and using the troubleshooter, this can indicate a hardware issue on the PC or motherboard; in that case, contact the device manufacturer’s support.
