What βNo Output Devices Foundβ Means in Windows
The message No output devices found means Windows currently has no usable playback device available. In practice, the missing device may be internal speakers, wired headphones, a Realtek sound card, HDMI audio from a graphics card, USB-C audio, a USB headset, or Bluetooth headphones.
The related warning No audio output device is installed usually points to the same group of causes: a disabled device, a stopped audio service, a broken driver, a failed Windows update, or a hardware/BIOS setting that prevents Windows from seeing the audio controller.
Quick Checks Before You Reinstall Audio Drivers
These basic checks often restore the output device without touching drivers. They are especially useful after connecting a monitor, TV, docking station, USB headset, or Bluetooth headphones.
- Restart the computer once. A restart reloads the audio stack, services, and device drivers.
- Disconnect USB headsets, docking stations, HDMI cables, USB-C adapters, and Bluetooth headphones. Then reconnect only the device you want to use.
- Check physical mute buttons on the laptop, keyboard, monitor, headset, or external speakers.
- Try another port. For example, move a USB headset from a front USB port to a rear motherboard USB port.
- For desktop speakers, confirm that the 3.5 mm plug is connected to the green audio output jack, not the microphone input.
- Install pending Windows updates, then restart again.
Likely software issue
- The device disappeared after a Windows update.
- Only one audio output is missing, but USB or HDMI audio still works.
- Device Manager shows a warning icon on an audio device.
Possible hardware issue
- No audio device is detected even in BIOS/UEFI or a live USB system.
- The headphone jack is physically damaged or loose.
- The same headset or speakers do not work on another computer.
Select the Correct Audio Output Device in Windows 10 and Windows 11
Windows can switch output automatically when you connect a monitor, TV, docking station, Bluetooth headset, or USB audio adapter. The speakers may not be broken; Windows may simply be trying to send sound to a different device.
Windows 11
- Press Win + I to open Settings.
- Open System β Sound.
- Under Output, select your speakers, headphones, HDMI monitor, or USB headset.
- Click the selected device and make sure Audio is allowed and the volume is not set to 0.
Windows 10
- Right-click the speaker icon on the taskbar.
- Choose Open Sound settings.
- Select the correct device under Choose your output device.
- If the list is empty, continue with the next sections.
Runms-settings:sound
Enable Disabled and Hidden Playback Devices
A playback device can be disabled in the classic Sound control panel. When that happens, the modern Settings app may show No output devices found even though the hardware is still present.
- Press Win + R.
- Run the classic Sound control panel command:
Runmmsys.cpl
- Open the Playback tab.
- Right-click an empty area in the device list.
- Enable Show Disabled Devices and Show Disconnected Devices.
- If your speakers or headphones appear, right-click them and choose Enable.
- Click Set Default, then test sound again.
Run the Windows Audio Troubleshooter
The built-in troubleshooter can restart audio services, correct default device settings, detect driver failures, and point to the exact device that is not working.
| Windows version | Where to open it | What to run |
|---|---|---|
| Windows 11 | Settings β System β Troubleshoot β Other troubleshooters | Audio or Playing Audio |
| Windows 10 | Settings β Update & Security β Troubleshoot β Additional troubleshooters | Playing Audio |
Apply any recommended fixes and restart the computer when prompted. If the troubleshooter says the audio service is not running, go directly to the next section.
Restart Windows Audio Services
Windows audio output depends on several services. If Windows Audio or Windows Audio Endpoint Builder is stopped, output devices may disappear from Settings and the taskbar sound menu.
Restart services from the Services console
- Press Win + R.
- Run
services.msc. - Find Windows Audio.
- Set Startup type to Automatic.
- Click Restart. If the service is stopped, click Start.
- Repeat the same check for Windows Audio Endpoint Builder.
Restart services with commands
Open Windows Terminal, PowerShell, or Command Prompt as administrator and run:
Command Prompt / Windows Terminal (Admin)net stop audiosrv
net stop AudioEndpointBuilder
net start AudioEndpointBuilder
net start audiosrv
Fix Missing Audio Devices in Device Manager
Device Manager is the main place to check whether Windows detects your audio controller at all. If the sound card is missing here, the Settings app cannot offer it as an output device.
- Right-click Start and open Device Manager.
- Expand Audio inputs and outputs.
- Expand Sound, video and game controllers.
- Open View β Show hidden devices.
- If your audio device is disabled, right-click it and choose Enable device.
- If a device has a yellow warning icon, open its properties and check the error code.
Rundevmgmt.msc
| What you see | Likely cause | Best next action |
|---|---|---|
| Realtek Audio is missing | Driver removed, disabled audio controller, or wrong chipset driver | Install the audio driver from the laptop or motherboard support page |
| High Definition Audio Device appears | Windows generic driver is installed instead of the vendor driver | Try vendor driver first; keep the generic driver only if it works correctly |
| Intel Smart Sound Technology warning | Intel SST or chipset driver problem | Install chipset, Intel SST, and audio drivers from the OEM support page |
| NVIDIA High Definition Audio or AMD High Definition Audio missing | Graphics driver installed without HDMI/DisplayPort audio component | Reinstall the graphics driver and include the audio component |
Reinstall, Update, or Roll Back the Audio Driver
Driver corruption is one of the most common reasons for No output devices found. Use this section carefully: remove the broken driver only when Windows still detects an audio controller or when you already have the correct installer available.
Install the OEM driver
Use the support page for your laptop, desktop, or motherboard model. This is best for Realtek, Intel SST, and laptop-specific audio packages.
Best compatibilityUse Windows Update
Open optional driver updates if the manufacturer package is not available or the device is a generic USB audio adapter.
EasyRoll back the driver
Use this if sound disappeared immediately after a driver update and the older driver worked correctly.
After bad updateUninstall and detect the audio device again
- Open Device Manager.
- Expand Sound, video and game controllers.
- Right-click your audio device and choose Uninstall device.
- If you see Attempt to remove the driver for this device, use it only when you have the correct replacement driver or Windows Update is available.
- Restart the PC.
- Install the manufacturer driver if Windows does not restore the device automatically.
Check optional driver updates
Look for audio, chipset, Intel SST, Realtek, AMD, NVIDIA, or device-specific driver updates. Install one driver category at a time and restart after each audio-related update.
Fix HDMI, DisplayPort, USB-C, and Bluetooth Output Devices
If the missing output device is not the built-in speakers, troubleshoot by connection type. HDMI, DisplayPort, USB-C docks, and Bluetooth headphones depend on different drivers and detection paths.
| Device type | What to check | Recommended fix |
|---|---|---|
| HDMI / DisplayPort monitor or TV | The monitor must support audio, be powered on, and be selected as output. | Reinstall the NVIDIA, AMD, or Intel graphics driver and include HDMI audio. |
| USB-C dock | Dock firmware, USB controller driver, and the correct USB-C port. | Update dock firmware and chipset/USB drivers from the laptop vendor. |
| USB headset or DAC | Different USB port, different cable, and device detection in Device Manager. | Remove the USB audio device in Device Manager, reconnect it, then set it as default output. |
| Bluetooth headphones | Pairing status, battery level, Bluetooth service, and whether the device is connected as audio. | Remove the Bluetooth device, restart Windows, pair it again, and select it under Output. |
Bluetooth-specific reset
- Open Settings β Bluetooth & devices.
- Remove the headphones or speaker.
- Turn Bluetooth off and on again.
- Put the device into pairing mode.
- Pair it again and select it in Sound β Output.
Repair Windows System Files That Affect Audio Detection
If output devices disappeared after a failed update, power loss, cleanup tool, or malware removal, Windows audio components or driver store files may be damaged. Use DISM and SFC to repair the component store and system files.
- Right-click Start.
- Open Terminal (Admin), Windows PowerShell (Admin), or Command Prompt (Admin).
- Run the commands below in order.
- Restart Windows after the scan completes.
Windows Terminal / Command Prompt (Admin)DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
After rebooting, check Device Manager again. If the audio device returns but has a warning icon, reinstall the vendor driver.
Check BIOS/UEFI Settings and Hardware If Windows Still Finds No Output Device
If Windows cannot detect the internal audio controller at all, check whether onboard audio is disabled in firmware. This is more common on desktop motherboards, but it can also happen after BIOS resets or firmware updates.
- Restart the computer and enter BIOS/UEFI setup. Common keys are Del, F2, F10, or Esc.
- Look for settings such as Onboard Audio, HD Audio Controller, or Azalia HD Audio.
- Make sure the audio controller is enabled.
- Save changes and boot into Windows.
- Install chipset and audio drivers from the device manufacturer.
When to use a temporary workaround
If you need sound immediately, use a USB headset, USB sound card, HDMI monitor audio, Bluetooth speaker, or external USB DAC. These devices use a separate audio path and can work even when the internal sound card is unavailable.
FAQ: No Output Devices Found in Windows 10 and Windows 11
Q Why does Windows say βNo output devices foundβ after an update? βΌ
Q Should I use Realtek drivers from Realtek or from my laptop manufacturer? βΌ
Q Why are HDMI audio devices missing? βΌ
Q Can malware cause output devices to disappear? βΌ
Q Is a clean Windows reinstall necessary? βΌ
π Bottom Line
The fastest way to fix No output devices found is to move from simple detection checks to driver repair in a controlled order. First verify the selected output device, then enable hidden playback devices, restart Windows Audio services, and inspect Device Manager. If the device is still missing, reinstall the manufacturer audio, chipset, graphics, or Bluetooth driver depending on the output type. Only after those checks should you suspect BIOS/UEFI settings or hardware failure.
