This's what is happening to my lappy (L502x).
(Please visit the site to view this video)
I have tried to:
- Uninstall audio drivers, then let Windows update automatically.
- Update to the latest Bios (A10).
- Upgrade Windows (from 7 to 10).
But all of that did not solve the problem. So I think this is a hardware issue.
My question is: Should the speakers, the subwoofer or both of them be repaired or replaced?
Thank you very much.
