How to Fix "No Audio Output Device Detected" in Windows 11

If Windows 11 shows “No audio output device detected”, displays a red X on the speaker icon, or cannot find your speakers or headphones, the cause is often a disabled device, an audio service problem, or a driver that is missing or failed to load. Start with the safest checks below before considering hardware replacement.

1. Check the obvious connections

  • Restart the computer and reconnect wired headphones or speakers.
  • Try another audio port if your computer has one.
  • For Bluetooth audio, confirm that the device is charged, paired, connected, and selected under Settings > System > Sound.
  • If a monitor is connected by HDMI or DisplayPort, check whether Windows selected the monitor as the output device.

2. Select and enable the correct output device

Open Settings > System > Sound. Under Output, choose the device you want to use. If it appears but is disabled, open its properties and select Allow. Also verify that the volume is not muted.

3. Run the Windows audio troubleshooter

Open the Get Help app, search for the audio troubleshooter, and follow the prompts. Microsoft recommends the automated troubleshooter because it can detect common configuration and service problems without requiring risky system changes.

4. Inspect Device Manager

  1. Right-click Start and open Device Manager.
  2. Expand Sound, video and game controllers and Audio inputs and outputs.
  3. If the expected device is present, right-click it and choose Enable device if that option appears.
  4. If it has a warning symbol, open Properties and note the error code. A Code 10 message means Windows could not start the device; it does not by itself prove whether the cause is software or hardware.
  5. Select Action > Scan for hardware changes.

5. Update, roll back, or reinstall the audio driver

In Device Manager, right-click the audio device and choose Update driver > Search automatically for drivers. You should also check Settings > Windows Update > Advanced options > Optional updates for an audio driver supplied through Windows Update.

If the problem started immediately after a driver update, open the device’s Properties > Driver tab and use Roll Back Driver when the button is available.

To reinstall the device, choose Uninstall device, then restart Windows. Do not select an option that permanently removes the driver package unless you already have the correct replacement from your computer manufacturer.

6. Install the manufacturer’s driver

If Windows cannot restore audio, visit the official support page for your exact laptop, motherboard, or prebuilt desktop model. Install the audio and chipset drivers recommended for your Windows version. Avoid third-party “driver booster” websites because they can supply incorrect or unwanted software.

7. Restart the audio services

  1. Press Windows + R, enter services.msc, and press Enter.
  2. Restart Windows Audio and Windows Audio Endpoint Builder.
  3. Confirm that their startup type is not set to Disabled.

When to seek support

If no audio controller appears in Device Manager after a restart, a hardware scan, Windows Update, and installation of the correct manufacturer drivers, check your manufacturer’s diagnostics or contact its support team. A missing device can be caused by software, firmware, a disabled onboard controller, or hardware failure, so replacing speakers should not be the first step.
