Where have you been looking?
What is the audio quality generally (bit depth, sample
rate, noise etc.)?
I notice that, as well as stereo in & out, they quote up to 8 I2S channels.
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.
How difficult would it be to create a jack
'endpoint' and control?
Once you have your environment set up, it is extremely easy. The hard
part is creating an environment where AVB works.
All through, my wish has been to get away from
soundcard obsolescence
(PCI?), vendor lock-in and software incompatibility. With the AVB standard
getting increasing support I believe that if any one compliant endpoint can be
supported, then eventually many others could be.
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.
