Hi again,
After the disappointment of only getting stereo
with the Monoprice adaptor, I had another look
and discovered some other offerings from a
company called Kanex
The most interesting one is this:
Kanex iAdapt 51 Mini DisplayPort to HDMI w/ 5.1 Channel Digital Audio
http://www.kanexlive.com/products/item.aspx?id=3495
It says
# Supports uncompressed 5.1 channel audio such as LPCM
# Supports compressed 5.1 channel audio such as DTS Digital, Dolby Digital
It's using the digital optical link to transmit
the audio (and specifically mentions that the USB
plug is not for the audio - just for providing
the power).
Anybody managed to test one? What does the LPCM mode offer?
Simon

Hi
For those of you who were wondering what happens when one of Monoprice's
MiniDisplay Port+ USB to HDMI connectors is used to connect a MacBook Pro
to a Home Theatre amplifier, I now know the answer, having ordered one and
had to pay a hefty charge to get it through customs here in France.

It just appears in Audio Midi Setup as a "USB Sound Device" with 0in/2out
and 2ch-16bit as the only option. You can choose between 44.1 and 48Khz.
That's it.... :-(
Oh, it sounds like nice quality stereo, and the Image on my flat screen TV
looks good at 1920*1080 pixels, but I'm disappointed that the audio
interface is so uninteresting.
HDMI based
audio communication is the future. I'm sure it's not beyond Apple's
engineers to come up with a MiniDisplay+USB -> HMDI that does it
properly....(or someone else?)
seems like whoever manufactured the current
interface needs to hear back from users that it
is not quite there yet.
Bill
Yours hopefully....
