Laptop Speakers Crackling at High Volume
4.5
The sound is clear at 50% but starts buzzing or crackling at 100%.
Symptoms
- Buzzing sound
- Distorted audio
- Vibrating chassis
Possible Causes
- Blown speaker cone
- Loose internal screw
- Software clipping
Step-by-Step Fix
1
Disable Audio Enhancements
Sound Settings > Properties > Enhancements > Disable all.
2
Check for Loose Screws
Sometimes a loose screw near the speaker vibrates against the case.
3
Lower the Pre-amp
If using an equalizer, ensure the "Pre-amp" isn't boosting the signal into distortion.
When to See a Technician
Laptop speakers are tiny and fragile; playing bass-heavy music at 100% can easily tear the paper cone.
