My speaker and my audio generate very loud high pitched noise after waking from sleep.
I had to mute my audio if this happens, but the speaker is essentially unusable in this situation.
If I plug in my headphone through audio jack, the high pitched noise will come from both headphone (and unmutable) and my speaker (if I turn on the volume).
I hope this is fixable through driver update.
Solved! Go to Solution.

I had the same issue. I tried reinstalling Windows, which seemed to help a bit, but didn't fix the issue. I submitted a service request and just sent the laptop back for servicing. Hopefully, this is a hardware issue they can fix.

Actually, mine got fixed after updating to the latest BIOS.
Find your model in Lenovo Support, and go to drivers, find and download the bios update utility and install the latest bios update.
