I'm sorry, but what I previously said about the detection is wrong. I guess I had some other changes around which broke it. However, I confirm that ALC668_FIXUP_AUTO_MUTE is not the solution, the subtle background noise is still there.
I would also like to add that there's a "clicking" noise when the audio card is disabled, loud enough (with my in-ear headphones at least) to make me disable the power saving mode. -- 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
