Some notes (this goes to LAU only please mirror to LAD if necessary):

Have a look into AVB it seems to become the de-facto standard if that is
possible (don't know about hardware/ethernet interface requirements)

Tim Blechmann has written an alsa driver for the digigram lx6464es card,
which is used in some ethersound products (Tim?)

Rimas Avizienis at CNMAT and Meyersound built hardware alongside a UDP
protocol to stream many channels of audio to custom built hardware, as
for example used in a 120 channel loudspeaker array:
