Hi and thanks for reporting and working on this bug!

First thing to know is that different machines have different PCI SSIDs.
For information about this, look at the "PCI SSID" section of
https://wiki.ubuntu.com/Audio/SameHardware

If you have PCI SSID 1028:05fe or 1028:060a, the fix for the noise issue
is upstream. You can test the daily drivers by following the
instructions here:  https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

The original poster has PCI SSID 1028:05e3. If you have another PCI
SSID, the first step is to post your alsa-info in this bug. See
https://wiki.ubuntu.com/Audio/AlsaInfo - that will give us more
information about your hardware, including your PCI SSID. You can also
file a new bug using the "ubuntu-bug audio" command and give a notice in
this bug with a link to a new bug.

Hopefully I or some other audio developer will have time to look at it -
but unfortunately I can't promise any quick response right now.

Title:
  [XPS 12-9Q33, Realtek ALC668, Black Headphone Out, Left] Background
  noise or low volume

Status in “alsa-driver” package in Ubuntu:
  Incomplete

Bug description:
  When listening to sound on my laptop through headphones, there's a
  constant background hiss (which disappears only when all sound has
  been stopped for a few seconds. power saving I guess).

  I also need to turn the volume *way* down to 10% for the sound volume
  to be reasonable (it's way too loud otherwise).
