ARE the full 8 HDMI channels available?? As I read the spec, there was only stereo and this post
<http://www.raspberrypi.org/phpBB3/viewtopic.php?f=7&t=4101> on the RPi website does not really
clear it up much. If that means what it appears to say you'd need a HDMI audio breakout box with
internal DAC's (such as http://www.converters.tv/products/hdtv_to_hdtv/698.html or the Gefen boxes
http://www.gefen.uk.com/index.php) to get access to it and they're more expensive than a cheap usb
audio box.

Why not just use the 8 HDMI sound channels?
Can you get jack and ambdec compiled for raspberry-pi?
http://offog.org/code/potamus.html is a small player that can play ambisonic
files via jack and ambdec.
I would love to know it is available, I have not yet ordered a raspberry pi.

Subject: [Sursound] ultra-cheap m/c USB cards for the R-Pi?
Hi,
I am setting up my new Raspberry Pi (Debian Linux), and am interested in any
comments, recommendations etc regarding the various really low-cost USB devices
around (e.g under £40, some as little as £12) offering 5.1 or 7.1 outputs -
e.g. Terratec, StarTech, Digiflex; in case any of them are worth taking a
chance on to get surround out of the Pi. Obviously I am not expecting stellar
audio quality (or anything better than 16/48), but they need to use chips that
alsa knows about, such as C-Media and be as far as is possible a
class-compliant USB device. I can easily build the multi-channel toolkit for
the Pi, but there is no point if a surround output is unachievable. Anyone
else exploring the Pi? Needless to say, a simple stereo USB card is no problem;
I have my Edirol UA-1EX working nicely for output.
