Bug Description
Since linux-image-
This is a regression in a stable release (Bionic). The problem consistently reproduces as follows:
OK: linux-image-
BAD: linux-image-
BAD: linux-image-
BAD: linux-image-
Steps to reproduce:
Hardware: Dell XPS 9360 (shipped with Ubuntu). I'm using a manually reinstalled Ubuntu Bionic, not the OEM installation. Mostly everything is on defaults.
1. Boot with no headphones connected
2. Log in
3. Plug the headphones in
Expected: normal noise level
Actual: very high noise level. Playback does work correctly but the SnR is terrible.
The "Select Audio Device" prompt appears, but the noise problem is present before I make a selection. If I select Headphones or Headset (I'm using a headset) then the noise remains after a brief (~0.5s) interruption. If I select Microphone then the noise goes, but then the audio comes through the speakers and not the headset as required.
I have tried messing with alsamixer but haven't found anything to explain or reduce the noise. Switching to a previous kernel fixes the problem immediately with no settings change required.

> I'm using a manually reinstalled Ubuntu Bionic
Actually it looks like I upgraded up to it from Artful.
