I'm not sure if I have the same problem, but definitely a similar one. I have a Dell XPS 12-9Q33 as well. The main difference is, that the weird noises' volume doesn't change when I turn the volume up or done, while the actual sounds' volume (music, whatever, ...) changes. I disappears when I mute though.
How do I apply this patch? https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda/patch_realtek.c?id=73bdd597823e2231dc882577dbbaf8df92fe1775 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1252733 Title: [XPS 12-9Q33, Realtek ALC668, Black Headphone Out, Left] Background noise or low volume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1252733/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
