Kernel behavior summary:

Ubuntu 4.4.0-59: HDMI audio works properly

Mainline 4.4 (any): i915 drm driver does not seem to support Skylake, HDMI audio not enumerated

All of the below kernels exhibit the same problem: HDMI produces no sound
Mainline 4.5rc1
Mainline 4.5 final
Mainline 4.6 final
Mainline 4.7 final
Mainline 4.8 final
Ubuntu 4.8.0-34
Mainline 4.9 final
Mainline 4.10rc5

From here, it's not clear to me how to bisect between the working kernel and any of the not-working kernels without breaking the back-ported i915 driver along the way.
