Bug ID: 235970
Summary: Distorted sound in headphones on Lenovo ThinkPad T480
Product: Base System
Version: 11.2-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: misc
Assignee: [email protected]
Reporter: [email protected]
I've tried to use headphones on T480 but the sound is distorted. It is
distorted with any application apparently (tested with VLC and Firefox) so it
seems to be a system problem. The sound quality is awful. It is possible to
hear that it is some music playing for example by the rhythm of the noise but
it is not a particularly pleasant experience. ;)
I'm on FreeBSD 13.0-CURRENT (r344237) amd64.
