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

Hello all,
Are there any of you here who are using AVB on Linux, especially with
a standard Ethernet port? What software or hardware are you using to
do this on your Linux machines? I am interested in playing with it
and have some AVB speakers to mess with, but I'm not sure if it is
even possible yet, especially with a standard laptop Ethernet port.
Tell me about your Linux AVB success stories!
None yet... :-(
Regarding the use of i210 network interfaces, a while back I found this:
https://github.com/AVnu/OpenAvnu/issues/601
----
At the top-level of the OpenAvnu checkout, run this make command:
$ PLATFORM_TOOLCHAIN=generic make avtp_pipeline
That will prevent it from linking to the i210 library and instead use
the standard Linux network stack. The packet launch times and
presentation timestamps will be
far less even and I'm working on ways to lessen those problems, but
you should be able to get a talker and listener built from the
avtp_pipeline code to work toge
ther with some tweaking of the avtp_pipeline INI files. Be sure to
read through the documentation that comes with the avtp_pipeline code.

But never had a chance to test it and see if it really works...
Then there is this software:
https://github.com/Drumfix/avb4linux.git
This is just 8 ports i/o on linux for motu avb cards, but it needs an
i210 NIC (by the same guy that posted an experimental driver for
proprietary usb mode on Motu's - in the LinuxMusicians forum - so you
can get 64 channel i/o over usb with the newest firmware - I am using
it and it works quite nicely).
