Similar dmesg for when you connect directly to the tv (and audio works)
might prove useful.

Is your expectation that the VSX-928 picks up the sound, or pass through
to the tv? Is it possible to try both (I honestly don't know)?

It might prove useful to file a bug on DRM/Intel at [1] to track
this. Then it won't get lost even if this thread quiets down.

Thanks,
Jani.
