Bill,
So, you've convinced me that HDMI is the solution, and that with the
USB+MiniDisplayPort -> HDMI connection, there could well be a
solution that doesn't just work for uses of the new iMacs.
hope so :)
In the meantime, can you tell me what a Home Theatre Amplfier looks
like from a new iMac via the Audio Midi Setup utility?
What options are available for formats like the frequency (44.1, 48,
96 KHz etc) and the number of channels?
Depends on the receiver and how much capability is being exposed
through the HDMI link. AMS will display the capabilities we see
through the HDMI link's EDID. There is also (and probably this will be
ongoing) attempts to workaround known inaccuracies for receivers where
the EDID is incorrect :)
Does the Configure Speakers... tab work? Can you select the
Multichannel configuration (5.1 surround, 6.1 surround, 7.1
surround, Quadraphonic, Hexagonal, Octogonal etc)??
Yes
If all of those things work, then yes, the solution is already with
us....

supported in released products.
I see little future for SPDIF - you can't even use it to reliably
transfer 24bit audio at 48kHz - and there is no discovery mode that
can tell you whether what you are doing is even supported or
possible... It is quite possible to output Dolby Digital or DTS
over spdif and listen to very nasty noise.... To make a better user
experience you really need to know what the capabilities of the
devices are - so the EDID mechanism of HDMI/DP is a fine solution
to this. ADAT is even worse than SPDIF from a compatibility point
of view (less devices support it), so I see no future in this.
