Hi,
I am using embedded linux on ARM processors in another project, and have
been looking for a simple solution for multichannel outputs for a while
(8 or more), although inputs also are interesting. I have implemented a
noisy soundcard based on UCB1400 for my hardware a while ago, and could
do some tests with that.

I could do parts of:

1) testing OSC on ARM/embedded Linux
(Don't know whether I could test netjack - I have no experience with
that)

2) test sending sound to/from the board
(but restricted to 10mbit/s, at the moment)

5) add the preamp part - there are good examples for that in the
datasheets for some differential amplifiers

Actually, if we go for this together, I'd suggest using a gumstix board
for the tests, or something similar that is completely ready. This would
make it easier to split the project into hardware and software, and it
would enable others to buy off-the-shelf material, or run a
software-only solution.

/ Hans
