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

@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

@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. The second point I was trying to say: Of course the white noise is audible when nothing is

Please try both cable types of the Bose Quiet Comfort (assuming you have two). And you might want to try my favourite trick of plugging in via a headphone splitter/extension/adapter. Sometimes you just have to piggyback on a different connector to get a clean connection. I'm not saying the

Out of curiosity I tried my Bose Quiet Comfort 15s, and I can't detect the hiss in those at either a dB gain of 0.00 or 10.00 with the headphone mic boost. That is odd. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

I would like to say I have plain old Sony earbuds, and the sound is very noticeable without playing any sound what so ever. As previously mentioned, upping the dB gain on the headphone mic boost from 0.00 to 10.00 completely stops the hissing for whatever reason. Also, the Arch Linux wiki has
