just to add my experience.

I am now running some Olimex A10-Lime with amplifier boards on a sound installation and it works quite stable.

Test-board see:

http://puredata.info/docs/embedded/olinuxino/algo_a10board_05_cut.jpg/view

I compiled jackd myself excluding dbus service so it worked, but did not get

a better performance so I use pd with ALSA directly.
