--- Comment #2 from Ilia Mirkin <imirkin at alum.mit.edu> ---
There is only HDMI audio support starting with NV84. If you're interested in
helping to get this to work, please collect a mmiotrace of the nvidia
proprietary driver that captures a plug and unplug HDMI event. (i.e. start it
without hdmi, then plug hdmi in, then unplug it.) Please be sure to add trace
markers (echo stuff > /sys/kernel/debug/tracing/trace_marker) before/after you
perform each of those things. I guess it wouldn't hurt to also try playing
something over HDMI, but I doubt that anything actually happens when you do
that. [Please make sure it's an audio-only thing, as video would rather
complicate the trace.]

There are some instructions on how to do an mmiotrace at
https://wiki.ubuntu.com/X/MMIOTracing

The resulting trace file should be 50-100MB, so please compress it before
uploading. (And if it's just a few KB, you did something wrong.)

Also upload a copy of your vbios (/sys/kernel/debug/dri/0/vbios.rom if you're
running nouveau).
