Fix: Computer Does Not Detect Your Headphones
Calm, ordered steps for when you plug in your headphones and your computer keeps the sound playing through the speakers anyway.
Check the Obvious First
Headphone jacks are surprisingly fragile. Lint or dust inside the socket can prevent the contact switch from registering. Look inside with a torch and clean gently with compressed air or a wooden toothpick if you see debris.
Try a different pair of headphones if you can. If a second pair is detected and the first is not, the cable or jack on the original headphones is probably worn out.
Sound Settings and Default Devices
Open Sound settings on your computer and look at the playback devices. Headphones may be detected but not selected as the default. Click them and choose 'Set as default device'. The audio should switch immediately.
On laptops, the front panel jack is sometimes treated as a separate device from the rear speakers. The settings panel makes the relationship clearer than the small toolbar icon does.
- Inspect the jack for dust or lint
- Try a second pair of headphones to isolate
- Confirm headphones are set as the default playback device
Driver and Codec Settings
Some audio drivers (common audio/network chip's in particular) include a jack-detect feature that you can disable accidentally. Look in the common audio/network chip Audio Console or your laptop manufacturer's audio app for an option labelled 'jack detection' or 'plug-in detection' and confirm it is enabled.
If the audio driver is generic Windows HD Audio, install your laptop manufacturer's audio package — the generic driver does not always handle jack detection on every chip.
