powertop (Ubuntu)

Bug Description

When powertop is actived, I have a unbearable whistling in 3.5mm jack headphones.

When powertop is disabled, I have not problem with my 3.5mm jack headphones.

Dell 9570 XPS 15 / Realtek ALC3266 audio card / Linux Mint 19.2 based on Ubuntu 18.04 / same problems on Ubuntu 18.04 and Debian 10 Buster.

History of the problem :


The current version of powertop is 2.11 :


It would be advisable to migrate as quickly as possible to this version for all Debian / Ubuntu systems. This driver is very important for good system stability in energy saving mode. I hope you all do your best to keep it up to date in the future.

If you need help for more details or tests feel free to send me an e-mail.

I dare to hope for a quick/urgent fix from you.

Best regards.
