To fix this bug, I filed a bugzilla bug to upstream:

And in the comment 8 of this bugzilla bug, one Intel engineer suggested to apply
these 3 patches, the patch 1/3 and 2/3 was already accepted by upstream maintainer
and is going to be merged to the mainline kernel, the patch 3/3 is in discussion.

We applied these 3 patches both to linux-4.14-rc8 and artful kernel, they all worked
well (HDMI audio worked well and graphic worked as before). Since the OEM project
is waiting for these patches, we need to merge this patch to oem kernel first.

  UBUNTU: SAUCE: drm/i915: set minimum CD clock to twice the BCLK.

Ville Syrjälä (2):
  UBUNTU: SAUCE: drm/i915: Track minimum acceptable cdclk instead of
    "minimum dotclock"
  UBUNTU: SAUCE: drm/i915: Consolidate max_cdclk_freq check in
