I'm not familiar with jack detect. Looking up the mobo and the specs, it looked
like only the -700 version had HDMI, but looking at a photo of the board, there's
an HDMI jack, as well as a DVI. The specs I saw did not mention the HDMI characteristics.
Like another reponder, I would think that if a board has an HDMI jack, then full
HDMI _ought_ to be provided.

What happens if you disconnect the local video monitor and the analog sound outputs?
Can you then get sound out of the TV? While the local sound and video are disconnected,
run the sound test routines from the command line, and see if you ever get sound on
the TV. If so, then the question is how to get sound from both sound processors? I
only know of PulseAudio, as I mentioned previously. If not, then I think the HDMI
output is not a true HDMI, or is faulty.

I don't know if it's possible to query ASUS about the properties of the HDMI
connector, but if so, then do so. If you bought and installed the mobo yourself,
you should have a booklet on it, and it may give more specs than I found on Google.

Good luck!

BTW: When I finally got the sound working on both systems, I discovered something
that I should really have known anyway: the sound out of the TV is _terrible_!
I have reasonable fidelity at the computer, but sure not at the TV. I have connected
an outboard amp and a pair of bookshelf speakers to the TV audio output jack!
So if you're going to watch and listen to musical performances, be warned!
