Model: Lenovo Legion Slim 5 Gen 9 (16AHP9)
Describe the issue:
Crackling sound/static sound coming from the laptop due to most likely the Lenovo System Update 2.0.13.18 from Windows, (could not be the update but I only discovered this issue after 3-4 months of daily use which is yesterday and that update is recent)
What have you tried already?:
Reinstall bios from lenovo official website.
Issue still on going
