Wow! Fantastic response .. lots to think about. Will let you know how I get on. Part of the problem
is hardware as I was unable (at the time I got this board) to find a case with a HD Audio front
panel so it currently thinks it's running in AC97 mode, but I'm going to knock something up to get
round this. In the mean time I'm going to play with the suggestions people have made (Puppy is
currently booting).
I'm also interested in the paper that Fernando gave us a link to. Although I don't want to use the
Mamba hardware, I _am_ interested in the possibilities for a dedicated multichannel player for
installation work (another retirement project!) What I'm looking at at present is a multichannel dac
linked directly (not via USB or owt like that) to an Arm processor that'll just play a multichannel
file off of a USB stick or SD card. For prototyping I'll be using a BeagleBone (as I definitely
don't want the extra bells and whistles of the BeagleBoard itself) - I'd prefer to use the RPi but
the chip used (at least, according to the manual) appears to have a crippled McASP port that can
only handle stereo, whereas the ARM on the BeagleBone has a good enough implementation of McASP that
it can do 16 channels at 48k for definite (EAOE) and probably up to 96k without too much trouble. If
initial tests prove the concept, I'll look KickStarter funding. The idea is to have an absolutely
rock solid box that just plays stuff without any of the hassles of systems relying on computers (ha!
That'll be the day)) The most it would have is an on/off switch and play controls - but it would
output up to 16 channels, balanced, 24 bits.

Indeed!
Let us know how the beagle board perform with a port of Planet CCRMA. ;-)
I will, I just have to find the time to test. I'm curious whether a small box like that can drive
1/2 of the Mamba box I was driving from a regular desktop. 32 channel playback through an ethernet
port[*]...
