Follow these steps on the affected Windows device to troubleshoot the Bluetooth headset that shows as connected but has no sound or stops after a few seconds:
- Run the Bluetooth troubleshooter
- On Windows 11 or Windows 10, open the Get Help app and run the Bluetooth troubleshooter using the built‑in entry:
- This runs diagnostics and attempts to automatically fix Bluetooth audio issues such as “connected but no sound.”
- On Windows 11 or Windows 10, open the Get Help app and run the Bluetooth troubleshooter using the built‑in entry:
- Verify output device and volume
- Click the Sound icon in the taskbar and ensure the Bluetooth headset is selected as the audio output device.
- Go to Start > Settings > System > Sound.
- Under Output (Windows 11) or Choose your output device (Windows 10), select the Bluetooth headset.
- Confirm volume is not muted and is set to an audible level.
- Adjust audio format
- Windows 11:
- Go to Start > Settings > Bluetooth & devices > Devices.
- Select the Bluetooth headset, then select Advanced sound properties.
- Under Output settings, set Format to 2 channels, 16 bit, 48000Hz (DVD Quality).
- Windows 10:
- Right‑click the Sound icon in the taskbar and select Sounds.
- Open the Playback tab, select the Bluetooth headset, and click Properties.
- On the Advanced tab, under Default Format, select 2 channel, 16 bit, 48000 Hz (DVD Quality), then Apply and OK.

- Select Start > Device Manager.
- Expand Bluetooth, select the Bluetooth adapter (may include “radio” in the name).
- Right‑click and choose Update driver > Search automatically for updated driver software.
- Complete the wizard, then restart the device if prompted and test the headset again.
- If the issue started or worsened after a Windows upgrade or update, update the Bluetooth adapter driver:
- Confirm A2DP support on the headset
- Check the headset documentation or manufacturer’s website to confirm it supports the A2DP profile (required for high‑quality audio streaming). If it does not support A2DP, Windows may connect for control but not stream audio reliably.

If the issue persists after these steps, collect details such as the exact headset model, Bluetooth adapter model, and whether other Bluetooth audio devices show the same behavior, then proceed with more targeted Bluetooth troubleshooting using the guidance in Fix Bluetooth problems in Windows.
