There are multiple variables here you need to consider... The headset socket is 4-contact to support headphones with built-in microphone. So if you plug in a 4-contact jack then you are more likely (not guaranteed) to get a clean connection (4 contacts touching 4 separate contacts).
However a "clean" connection is not helpful if you've plugged in the wrong type of headset. See there are different types (too many): https://technosyndicate.files.wordpress.com/2012/12/122312_0549_common35mm11.png http://www.cablechick.com.au/blog/understanding-trrs-and-audio-jacks/ So an imperfect connection is pretty common. And an imperfect connection might touch the laptop's mic contact to something else. In fact if you get a pair of Bose Quiet Comfort QC25 then you have a choice between buying one with Apple support or Samsung/Android support (although some stores will only stock Apple). One doesn't work in the other but they both appear to be identical 4-contact 3.5mm jacks. Yes indeed this can be fixed in software to silence or reduce noise from the mic line. But remember it's a hardware problem as well as a software problem. You should try both hardware and software solutions. -- 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: XPS 13 9360, Realtek ALC3246, Headphone audio hiss To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1654448/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
