Sb, the next step is to fully commit bisect from kernel 3.19 to 4.2 in
order to identify the last good kernel commit, followed immediately by
the first bad one. This will allow for a more expedited analysis of the
root cause of your issue. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

Title:
  [15.10 Regression] LightDM unity-greeter login sound has noisy
  distortion after 15.10 Wily upgrade

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hi, I just upgraded from Ubuntu 15.04 to 15.10 beta. Now when the LightDM unity-greeter screen appears, it produces a loud distortion noise where the Ubuntu drums should sound. It was working fine in 15.04 and all prior versions. Apart from this sound works fine after logging into Ubuntu.
