The openavnu repository would be a start but I
don't know of
anyone that has a full stack working.
On a pretty long thread on the Ardour forums someone recently wrote this:
"The ALSA driver (based on the intel igb driver) can use any buffersize
down to a single interval.
"The lowest round trip latencies (analog to analog) on my 16A therefore
are 1.5ms at 6/48kHz to 0.75 ms at 24/192kHz measured with jack2 in
synchronous mode."
No response after several days to my request for a link to a repository
containing that ALSA driver.
