OK, then it could be rather the video-driver side problem.
Typically, there must be a register control to enable/disable the HDMI
audio in the video controller.

In ALC883 codec, there is actually a digital I/O and snd-hda-intel
enabled it.  However, how the rest is handled (i.e. SPDIF or HDMI)
is out of the scope of the audio codec.

Thanks, a similar fix was already merged now.
