Headphones are not detected

Establish the scope

Identify whether the headset is analog, USB, or Bluetooth. An analog jack may use the existing speaker output name, while USB and Bluetooth devices have their own connection path. Compare selection and actual playback before treating the absence of a new headphone label as non-detection.

Apply the safer fix first

For analog sets choose the output and OEM jack prompt; for USB use a direct port; for Bluetooth remove and pair again.

Investigate the cause

Show disabled playback devices and update the PC maker audio driver. Confirm the headset plug type matches the jack.

Protect the recovery path

Lower volume before reconnecting. Do not force an incompatible plug; use another working input device before removing a Bluetooth pairing needed to control the PC.

Verification

• Select the intended playback path and play a known recording through the headset.
• Reconnect by its normal method and confirm sound returns to the headset rather than the speakers.

When to stop

Do not continue with broader resets when the plug or port is damaged or the headphones also fail on another compatible device. Preserve the observations already collected and use the device maker, network administrator, Microsoft support, a qualified repair technician, or data-recovery help according to the evidence.

Review the safe troubleshooting workflow before any broader recovery step.
