Headphones not detected: how to fix it on Windows 11

Applies to: Windows 11 PCs where wired (3.5 mm or USB) or Bluetooth headphones are plugged in or paired but don’t appear as an output, or where Windows reports “No audio output device is installed”. The Microsoft pages cited here cover Windows 10 too. If the headphones are listed but silent, our no sound in Windows 11 guide is the better starting point.

Match your symptom

The table is general guidance to help you skip ahead; the fixes that follow say which steps come from Microsoft.

What you see	Start with
Headphones work on a phone but never appear on the PC	Fix 2, then Fix 3
They appeared before, then vanished from the Output list	Fix 1, then Fix 3
“No audio output device is installed” or Sound settings grayed out	Fix 3, then Fix 6
Bluetooth headphones are paired but missing as an output	Fix 5
Problem began after a Windows update or driver change	Fix 6 (roll back), then Fix 8
USB headset shows an error code in Device Manager	Our USB audio Code 10 guide

Why Windows doesn’t see the headphones

Microsoft’s page Fix missing or undetected audio output device in Windows says Windows may fail to detect an output device when the audio driver is missing, outdated, disabled or not loading correctly. It adds that this can follow a Windows update, a driver change, or corruption of the driver or hardware. The symptoms it lists are a “No audio output device is installed” message, Sound settings that are unavailable or grayed out, and speakers or headphones missing under Output in Sound settings.

As general guidance, a physical fault can look the same from Windows’ side: a plug that isn’t fully seated, a front-panel jack on a desktop case that isn’t wired to the motherboard, a worn cable or a USB port that has lost power. That’s why the cheap checks come before the driver work.

Fix 1: Look in the Output list and the Sound control panel

Headphones sometimes show up under a name you don’t expect, such as the headset model, the USB adapter or the sound chip. Select the speaker icon on the taskbar, then the arrow next to the volume slider; Microsoft’s Fix sound or audio problems in Windows page uses this list to confirm sound goes where you want. You can also open Settings > System > Sound and look under Output. Selecting a device there also makes it the default, according to the same page.

A device that was turned off by hand won’t appear as an output. Microsoft’s steps for finding it:

1. Open Settings > System > Sound.
2. Under Advanced, select More sound settings and stay on the Playback tab.
3. Select the headphones, choose Properties, and set Device usage to Use this device (enable).

If the Playback tab looks empty, right-click inside the list and turn on the options to show disabled and disconnected devices. That right-click menu isn’t on Microsoft’s page; treat it as general guidance.

Fix 2: Check the plug, jack and port

Microsoft’s hardware checks that apply to headphones:

• Make sure each cable sits in the correct jack. Some PCs use a green jack for output and a pink one for a microphone; others label the jacks “headphone” and “microphone”.
• Confirm the device is powered on.
• Try a different USB port.

Beyond Microsoft’s list, some general checks: push a 3.5 mm plug in until it clicks, since a half-inserted plug may not trigger the jack’s detection. On a desktop, try the rear jack on the motherboard instead of the front panel. Test the headphones on a phone to rule out the headphones themselves. With a USB-C or USB dongle, test the dongle on its own, and plug USB headsets straight into the PC rather than through a hub or dock while you test.

Some PC makers include their own audio app with settings for jack detection or for what a combined headset jack does. If your PC came with one, check its settings; the names differ from maker to maker.

Fix 3: Enable the device or rescan in Device Manager

This is the first solution on Microsoft’s undetected-device page:

1. Select Start, type Device Manager and open it.
2. Expand Sound, video and game controllers.
3. If the audio device is listed, right-click it (or press and hold) and select Enable device if that option appears.
4. If it isn’t listed, select View > Show hidden devices, then Action > Scan for hardware changes.

A rescan asks Windows to look for devices again without a restart. As general guidance, a device with a yellow warning icon has a driver problem rather than a detection problem; open it and read the status message before moving on to Fix 6. A USB headset with Code 10 has its own guide.

Fix 4: Run the audio troubleshooter

Microsoft points Windows 11 users to the automated audio troubleshooter in the Get Help app, which runs diagnostics and tries to fix what it finds. Microsoft’s main sound page also gives a Settings route: Settings > System > Troubleshoot > Other troubleshooters, then Run next to Audio. As general guidance, plug in or connect the headphones before you start, so the troubleshooter can see them if Windows picks them up.

Fix 5: Bluetooth headphones that don’t show up

Bluetooth headphones need to be connected, not just paired, before they appear as an output. Microsoft’s Fix Bluetooth connected but no sound issue on Windows page covers this case. Its steps, in a shorter form:

• Check that the Bluetooth headphones are selected in the taskbar sound panel, or under Output in Settings > System > Sound.
• If the headphones appear but won’t connect, go to Settings > Bluetooth & devices, open More options (…) next to them, select Remove device, then Add device and pick them from the list.
• Turn Bluetooth off in Settings > Bluetooth & devices, wait 10 seconds, turn it back on and pair again.
• Update the Bluetooth driver: in Device Manager expand Bluetooth, right-click the adapter (its name may include “radio”), select Update driver and let Windows search automatically, then restart if asked.
• Check the headphones’ documentation to confirm they support A2DP, the Bluetooth profile for higher-quality audio streaming.

As general guidance, put the headphones into pairing mode before Add device (the button or gesture depends on the model), and disconnect them from a phone or tablet nearby, since some headphones connect to only one device at a time. If Bluetooth itself is missing or won’t turn on, see our Bluetooth not working guide.

Fix 6: Install, reinstall or roll back the audio driver

A missing or broken audio driver is one of the causes Microsoft names for an undetected output device. Its undetected-device page says to download the latest audio driver for your Windows version from the PC or sound card maker’s support site, install it and restart. The main sound page adds these options in Device Manager, under Sound, video and game controllers:

• Update: right-click the audio device, select Update driver and search automatically.
• Reinstall: right-click the device, select Uninstall device, select the Attempt to remove the driver for this device checkbox, uninstall, then restart so Windows reinstalls it.
• Generic driver: select Update driver > Browse my computer for drivers > Let me pick from a list of available drivers and choose High Definition Audio Device.
• Roll back: if audio worked before a Windows update, open the device’s Properties, go to the Driver tab and select Roll Back Driver. If that’s not available, Microsoft suggests a restore point.

Fix 7: Restart the audio services

Microsoft’s main sound page says to open Services and restart Windows Audio, Windows Audio Endpoint Builder and Remote Procedure Call (RPC). To open Services, search the taskbar for services. Right-click each service and select Restart where that option is available. As general guidance, Endpoint Builder is the service that keeps track of audio devices, so restarting it can bring back an output that dropped out of the list.

Fix 8: Install updates and restart

Microsoft’s main sound page and its Bluetooth page both list Windows Update: go to Settings > Windows Update, select Check for updates, install what’s offered and restart. The undetected-device page ends with a restart from Start > Power > Restart, after which you check whether the device appears. As general guidance, a full restart also resets USB ports and the Bluetooth radio, which a sleep and wake cycle doesn’t.

If the headphones have a microphone that Windows also can’t find, the steps in our microphone not working guide cover input devices and privacy settings.

Known issues

Microsoft lists confirmed Windows 11 problems on its Windows release health pages. If the headphones disappeared right after an update and the fixes above don’t help, check those pages and the support site of your PC or headphone maker.
