Hello.
Some users included myself have noticed coil-whine-like noises coming through the headphones after the computer resumes from sleep. This noise
is
clearly associated to the laptop activity, e.g. when scrolling through a webpage or compiling something, the processor can be heard doing the
work.
Interestingly, the coil whine that can be heard from the computer with naked ears (which is a common problem with this laptop) is also increased after resume.
The problem has been observed on a Dell XPS 13 9360 with an i7-8550U CPU
by
myself, as well as with an i5-8250U by a user in the Arch Linux forums https://bbs.archlinux.org/viewtopic.php?pid=1759588#p1759588. This
user
has also noticed that reloading the snd_hda_intel module fixes the issue.
Please let me know of any inormation that would be needed to debug this problem.
A few XPS13/15 models have the workaround for such issues. They are applied per PCI SSID matching, so your model might be missing there? 1028:05fe, 1028:060a and 1028:060d are matched, so far. But it's for ALC662 variant, and the recent machine may have a different codec, too...
In anyway, the hardware detail information is missing. Please give the output of alsa-info.sh (run with --no-upload option).
