Move the laptop and lower volume

A desk, case or loose object can resonate with bass. Place the laptop on a solid surface and test again at moderate volume.

Step 2

Compare speech, music and a clean sweep

Buzzing in only one recording may be part of the source. A controlled sweep and spoken audio make persistent rattles easier to identify.

Step 3

Test headphones and output settings

Clean headphone playback suggests the issue is near the laptop speakers. Also disable extreme audio enhancements and confirm left-right balance.

Step 4

Treat liquid exposure differently

If the laptop was wet, switch off and disconnect power when safe, then follow the manufacturer’s service guidance. Do not keep driving a distorted speaker at high volume.

The short answer

If the laptop was wet, switch off and disconnect power when safe, then follow the manufacturer’s service guidance. Do not keep driving a distorted speaker at high volume.
