** Tags removed: trusty -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1580394 Title: [Latitude 3340, Realtek ALC3234] MATE - Headphone Static on Battery Power Status in alsa-driver package in Ubuntu: New Bug description: I have noticed that when I am on battery power on a Dell Latitude 3340 laptop with headphones plugged in , and there is no audio playing on the computer, there is a consistent static sound that comes through the headphones at a constant volume that is not affected by changing the volume level. I think it may be picking up some kind of analog loopback signal because keyboard presses and disk activity seem to influence the noise. When I plug the power cable into the laptop , the static immediately goes away. I reported this earlier to the upstream Linux Kernel bug tracker, but it seems to be fixed in any distro running a 4.4 kernel or greater that I have tested , Except for Ubuntu MATE 16.04 LTS 64-bit. This make me think it is not a kernel level issue and is found somewhere either in the audio settings on Ubuntu MATE or a pulseaudio bug. I cannot reproduce it on any other 16.04 distro version, but it also affects all the 14.04.4 distros as well. Running amixer -c 1 set "Loopback Mixing" "Disabled" does not prevent the static.
