If Windows cannot detect your headphones, start with the connection and selected sound output. If your Bluetooth headphones play music but lose sound or microphone access when a Teams or Zoom call starts, use the call-audio checks below: the headset is connected, but the microphone path may be failing.
Technical review: October 12, 2026. This guide covers Bluetooth call audio first, followed by general detection and playback checks. The updated steps reference Microsoft and Zoom support documentation.
Bluetooth headphones work for music but fail in Teams or Zoom
Try this first: in your calling app, select the Bluetooth headphones as the speaker and the laptop’s built-in microphone as the microphone. Run an audio test. If this restores the call, keep that combination for now while investigating the headset microphone. If it does not help, test a USB or wired headset, or the laptop’s own speaker and microphone.
Change one setting at a time and repeat the same test so you can identify what helped.
1. Find out whether Windows or one app is failing
- Close meeting apps and browser tabs using the microphone. Play a short audio file through the headphones.
- Open Settings > System > Sound. Under Input, select the headset microphone, open its properties and choose Start test. Speak, stop the test and play the sample. See Microsoft’s microphone testing steps.
- Run a Teams or Zoom audio test with the headset selected for speaker and microphone. Repeat with the laptop microphone instead. Note whether playback stops only when the Bluetooth microphone opens.
| What happens | What to check next |
|---|---|
| No sound during ordinary playback | Check the Windows output, volume and connection first. |
| The microphone works in Windows but fails in one app | Check that app’s devices, mute controls and permissions. |
| Opening the Bluetooth microphone stops playback outside the calling app too | Investigate Windows Bluetooth audio, drivers and updates. This test does not establish a single cause. |
| The call works, but sound becomes less detailed or mono | Check the Bluetooth Classic and LE Audio explanation below. |
2. Select the devices inside Teams or Zoom
Teams desktop: open Settings and more > Settings > Devices. Select the intended speaker and microphone explicitly. Use Make a test call if available and check the replay. Microsoft notes that this test is unavailable in Teams for web; controls can also vary by app and account. See Microsoft’s Teams microphone guidance.
Zoom desktop: use Settings > Audio to select and test your speaker and microphone. When joining a meeting, Test speaker and microphone lets you check the speaker sound and recorded voice. The arrow beside the meeting’s microphone control also lets you change devices. See Zoom’s audio testing instructions.
If only one app fails, update that app and retest before changing PC drivers. For a browser meeting, check the microphone device and permission for the meeting site too.
3. Check microphone access and mute controls
In Windows 11, open Settings > Privacy & security > Microphone. Check Microphone access, Let apps access your microphone and, for desktop meeting software, Let desktop apps access your microphone. Enable the app you intend to use where an individual control is available. Windows 10 puts these controls under Settings > Privacy > Microphone. See Microsoft’s permission instructions.
Check the headset’s physical mute switch and the app’s mute button, then retest the recording. An unmuted icon alone does not confirm that the correct microphone is receiving sound.
4. Separate lower call quality from a complete failure
Bluetooth Classic uses A2DP for high-quality stereo playback and HFP for microphone capture with mono call playback. Windows 11 normally switches profiles automatically when an app opens the headset microphone. Windows 10 can show separate Stereo and Hands-Free devices; calls using the headset microphone need the Hands-Free input and output. Microsoft documents these differences.
Less detailed call audio can be expected on a Classic connection. Losing both microphone and playback is a different symptom. A separate microphone can be a workaround, although a calling app may still request communications audio. Turning off hands-free functionality also removes the headset microphone, so it is not a fix when you need that microphone.
For LE Audio: check both the PC and headset specifications. In Windows 11, Settings > Bluetooth & devices > Devices may show Use LE Audio when available. A missing control can mean unsupported hardware or drivers; a Bluetooth version number alone is not enough. See Microsoft’s compatibility checks.
Stereo with the microphone active additionally needs Windows 11 24H2 or newer and compatible hardware and drivers. If your connected LE Audio device offers Settings > System > Sound > [headphones] > Output settings > Format > Format when microphone is active, try Mono (1 channel) if stereo causes glitches, then retest. Skip this step if the control is missing. See Microsoft’s LE Audio quality settings.
5. Check drivers and updates if the failure follows the PC
Record your Windows version and build with Win + R > winver. Check Settings > Windows Update and the PC manufacturer’s support page for Bluetooth and audio drivers for your exact model. Restart and repeat the test. If the issue began just after a Bluetooth driver update, check Device Manager > Bluetooth > [adapter] > Properties > Driver > Roll Back Driver when available. Follow Microsoft’s driver guidance; use your IT team’s approved updates on a managed work PC.
October 2026 context: users have reported Windows 11 25H2 cases where music plays but opening the Bluetooth microphone stops call audio. Microsoft’s September 22 KB5124010 preview notes mention microphone compatibility improvements for certain Bluetooth Classic accessories. The reader discussion records differing results. These reports do not establish a universal defect or a guaranteed fix for your setup.
6. Confirm the result before your next meeting
Repeat the Windows microphone test and the app’s audio test, then make a short call. Confirm that you hear the other person and they hear you. Reconnect the headset once and test again. If a built-in or USB microphone is your working fallback, select it explicitly before the next meeting.
If the failure remains, give support your PC and headset models, Windows build, Bluetooth driver version, app version and the test results. Include whether the headset works on another device.

If Windows does not detect your headphones at all
The truth is if Windows 10 does not recognize your headphones it can be for several reasons. The first thing is to make sure that the problem is not with our headphones , since they could have been damaged and this is the reason why Windows 10 does not detect them. To do this, simply connect them to another PC or sound system and check if they work correctly.
Check connection and update drivers
If this is so, then we must check the cable connections , but if everything is correct, then we can proceed to update the drivers of our sound card , since the problem may therefore be on the computer side. To do this, simply go to Device Manager, find our audio card and by right-clicking on it, select the Update driver option.
We can also do it manually by downloading them from the manufacturer’s website, we just have to identify the model and go to it. When updating, it will ask us if we want to use one that we already have on our computer or that it detects it automatically. If there is a newer one it will be installed on the system. Sometimes nothing appears and you have to install it or it will suggest if you want to search Windows Update. One of the main reasons that the headphones do not work are the drivers, so it is worth checking.
Run the audio troubleshooter
In Windows 11, open Get Help and run the audio troubleshooter. Follow the checks it offers, then play an audio sample through the headphones again. Microsoft provides the current route in its Windows sound troubleshooting guide. Older Windows 10 installations may still show troubleshooting controls under Settings > Update & Security > Troubleshoot.
Change sound format
Another thing that can help us in the event that Windows 10 does not detect your headphones is to change the default sound format . To do this, we right-click on the speaker icon on the taskbar to enter Sounds and then right-click on the device to access its Properties.
If when you want to do this you cannot find your device, this is the problem, which is probably not detected and it is due to the connection. So while you’re here you can try this check and reconnect your headphones if so.
Under Advanced > Default Format, try another supported format and test playback after the change. The highest sample rate is not automatically the most compatible choice. Restore the previous format if the change makes no difference. This playback setting cannot make an undetected device appear, and it is separate from the LE Audio microphone-active setting discussed above.
Restart the audio service
Another alternative to be able to solve the problems with our headphones in Windows 10 is to restart the system audio service. For it:
- We open a Windows Run window, Win + R.
- We write services.msc and press Enter or Accept.
- We look for the service called Windows Audio.
- We click on it with the right mouse button and select the Restart option.
Now we can test again if the system recognizes our headphones and if the sound is heard correctly through them. In many cases, the problem is solved with this simple check.
Check sound output settings
If nothing is heard through the headphones that we have connected to the computer, the system’s audio output may not be configured correctly. Therefore, we must:
- Right-click on the speaker icon displayed on the taskbar.
- We choose the Open Sound Settings option.
- In the Output section of the Configuration page we verify the output device.
- If they are not our headphones, we display the list and select them.
- In Windows 11, open Settings > System > Sound, select the headphones under Output, and use the output test if available. Microphone tests belong under Input.
You can also get there from Windows Settings, from start and the gear icon or with the shortcut Windows + I. Then give System and Sound.
If the Bluetooth headphones will not connect
Charge the headset, put it in pairing mode, and temporarily disconnect it from other devices while testing. Turn Bluetooth off and on once. If needed, in Windows 11 open Settings > Bluetooth & devices > Devices, remove the headset, then pair it again. In Windows 10, use Settings > Devices > Bluetooth & other devices. See Microsoft’s Bluetooth troubleshooting guide.
If pairing still fails, run the Bluetooth troubleshooter in Get Help. For a missing Bluetooth adapter, check the manufacturer’s specifications and drivers. Pairing again is useful for a connection problem; a headset that already plays music needs the call-audio checks above when only meetings fail.
Test on another device before considering repair or replacement. A Windows-only failure can involve settings, software or the PC’s Bluetooth hardware; it does not by itself show that you need new headphones.
