2019-09-30 13:44:53 Robie Basak description Since linux-image-4.15.0-60-generic 4.15.0-60.67, the background noise in my headphones has increased to unreasonable levels. In linux-image-4.15.0-58-generic 4.15.0-58.64 and previous kernels the noise was present but at a bearable level, which I had always assumed was a hardware design issue. Now, with the increased noise floor, the headphone socket is essentially unusable. This is a regression in a stable release (Bionic). The problem consistently reproduces as follows: OK: linux-image-4.15.0-58-generic 4.15.0-58.64 BAD: linux-image-4.15.0-60-generic 4.15.0-60.67 BAD: linux-image-4.15.0-62-generic 4.15.0-62.69 BAD: linux-image-4.15.0-64-generic 4.15.0-64.73 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.
