I've had this issue since 2017 all the time. As you can see in the comments, Kai suggested that this is an hardware issue. He developed a workaround for the kernel that I tested, however it made the general output volume significantly lower, see #96, which is the reason this fix was never shipped.
So it's really strange to me that you guys did not observe the issue until now. Are you all having the 9360 model or a newer one? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654448 Title: Dell XPS 13 9350/9360 headphone audio hiss To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1654448/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
