I've recently just run into the same problem since recent updates, I've had my XPS since October 2017 and am currently running Ubuntu 18.04.3. No issues until last week. I think I may have selected "headset with microphone" by accident once when inserting headphones without a microphone, but no evidence that this was related; I just remember doing it when I don't recall doing that before.
The initial workaround in this thread of updating "Headphone Mic Boost" setting up one notch in alsamixer works for me, so I assume this is a regression or was this never fixed? -- 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
