Thanks so much for these links Fernando. I've played with the OpenAvnu 
repo about 2 years ago, but I couldn't get it working as I didn't know 
what I was doing. I'll try compiling it with the standard Linux network 
stack and see how far I get.

I don't currently have a motu avb interface, but I do have access to an 
RME Digiface AVB <https://www.rme-usa.com/digiface-avb.html>. I'll look 
through those repositories, but I figure there's not much I can do with 
that interface on Linux as of yet. :(

What interface do you use to get the 64 channels over usb?

Thank you again Fernando,

Brandon Hale
