It sounds like the Windows approach of using a noise suppression filter might generally be a good idea. It's likely Microsoft has seen many more laptops and desktops with this same problem.
Although I can't help but think that we could still fix this by limiting the volume more (or finding some gain setting that is on but shouldn't be). Having headphone volume that doesn't go high enough is already a common problem plenty of people would be used to. But the important thing is they won't report that as a bug, so maybe that's better. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1654448 Title: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss Status in Dell Sputnik: Confirmed Status in alsa-driver package in Ubuntu: Confirmed Status in linux package in Ubuntu: In Progress Status in pulseaudio package in Ubuntu: Confirmed Bug description: Pertaining to 16.04 on a dell XPS 13 9360 ii alsa-base 1.0.25+dfsg-0ubuntu5 Advanced Linux Sound Architecture Driver Version k4.4.0-57-generic. When headphones are plugged in, there is a clearly audible hiss (white noise). This is present as soon as the headphones are plugged in, whether 'headphones' or 'headset' are selected from the pop-up box. Using alsamixer to debug the issue reveals that it is related to "Headphone Mic Boost" - the default setting is: dB gain 0.00, 0.00. If this is changed to: 10.00, 10.00 (one notch up) the hiss disappears. 20.00, 20.00 cause a louder hiss and 30.00, 30.00 causes an even louder hiss with high frequency audio artifacts. When the headphones are removed and plugged back in the Headphone Mic Boost setting returns to dB gain 0 and the problem also returns.
