Laptop unable to switch audio output
4.5
Sound keeps playing from speakers even when headphones are plugged in.
Symptoms
- Headphones not detected
- Manual switch doesn't work
- Dual output
Possible Causes
- Broken jack sensor
- Driver bug
- Default device setting
Step-by-Step Fix
1
Set Default Device
Right-click speaker icon > Sound Settings > Choose your output.
2
Check Jack for Debris
Lint in the jack can prevent the "plugged in" signal.
3
Reinstall Audio Driver
The driver handles the automatic switching logic.
When to See a Technician
If the laptop doesn't "see" the headphones, the physical sensing pin in the jack might be stuck or broken.
