Where have you been looking?

You can basically throw in whatever you want. AVB is a framework to
synchronise media clocks and handling streaming by combining already
known protocols and practices, with some sugar on top.

Once you have your environment set up, it is extremely easy. The hard
part is creating an environment where AVB works.

You are missing one important point: Synchronized media clocks. Unless
you have support for PtP and can timestamp your audio data in hardware,
you can pretty much forget it - except for very simple cases.

Machines can do the work, so people have time to think.
