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 Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1654448 Title: XPS 13 9360, Realtek ALC3246, Headphone audio hiss Status in alsa-driver package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed 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.

@vanvugt I do have both cable types (with and without cable mic). In testing the Quiet Comfort 15s: Bose CQ 15 w/ normal cable - The hiss is present with 0 dB headphone mic gain, but far more reduced than the Sony earbuds. It is almost unnoticeable. If I weren't trying to hear it, I'd miss it. Bose CQ 15 w/ mic cable - I cannot detect any hiss present with 0 db gain. @esokrarkose I'm sorry I misunderstood what you were saying about your experience with the hiss. I thought you were saying it only happened while playing a sound. I too experience the constant hiss with my earbuds. I don't doubt the hiss in normal headphones. The Bose CQs do produce the hiss with one cable type. It is barely noticeable and much more subdued than the earbuds. I'm not sure what Bose does if anything with the sound signal coming from the headphone jack. Maybe it's just reduced due to higher quality speakers than say my earbuds. As I understand it the noise cancellation is meant for external sounds, but like you said, maybe it plays a role in making the hiss less audible. The noise cancellation itself does produce a level of white noise. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1654448 Title: XPS 13 9360, Realtek ALC3246, Headphone audio hiss Status in alsa-driver package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed 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.

@spike speigel: The tlp issue in the arch Linux wiki is unrelated. The point I was that when tlp is installed and no audio is currently playing, tlp turns off the sound card and thus the hiss disappears.

I would like to share that I found this post referring to a similar issue where sound settings weren't maintained, maintained being a better word than saved because I believe alsamixer might properly save the settings. According to the post it is pulseaudio which is actually modifying the settings: http://askubuntu.com/a/549939 I tested as suggested, by modifying the "Headphone Mic Boost" within alsamixer and exiting. I then ran: pulseaudio -k And pulseaudio reset the "Headphone Mic Boost" to dB gain 0.00, 0.00. The hissing reappeared. If I could get pulseaudio to stop resetting the "Headphone Mic Boost" in alsamixer, then that would be an acceptable workaround. But, I think the real issue still needs to be resolved. One would expect a dB gain 0.00, 0.00 to be absolutely silent. The user should not need to kick it up a notch to dB gain 10.00, 10.00. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1654448 Title: XPS 13 9360, Realtek ALC3246, Headphone audio hiss Status in alsa-driver 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.

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.
