[Bug 1853528] [NEW] Buggy energy management of Realtek ALC3266 audio card

[Philippe]

Public bug reported:

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 :

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1841485

The current version of powertop is 2.11 :

https://01.org/powertop/

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.

Philippe
