hshan, the next step is to fully reverse commit bisect from kernel 3.19
to 4.1-rc1 in order to identify the last bad commit, followed
immediately by the first good one. Once this commit has been identified,
then it may be reviewed as a candidate for backporting into your
release. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

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

Thank you for your understanding.

Title:
  No HDMI Audio Source on Newer Kernels

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I am also experiencing this problem.
  Ubuntu 15.04

  TV plugged in HDMI port

  Problem happens with Kernel versions 3.19.0-17 and 3.19.0-18

  HDMI audio worked before upgrading from 14.10 to 15.04
  HDMI audio works if I select an older kernel (3.16.0-38)

  No hdmi source seen on newer kernels, not on pavc either.
