There is a fork of the Merging driver which has been updated to compile cleanly on newer kernels which can be found here:
https://github.com/bondagit/ravenna-als ... s67-daemon

I'm currently trying to find a stable configuration which this fork of the driver on an embedded device based on the 5.15 kernel. The binary build of the user space butler daemon will not run on modern Linux distributions without hacking around libcurl dependencies as reported in other threads. I have had some success using https://github.com/bondagit/aes67-linux-daemon in combination with Anubis/Hapi interfaces. While one can configure the streams manually I've found that the Linux driver is prone to glitches and dropouts on every configuration I've tried from Celeron based mini pc to top a top shelf AMD Threadripper workstation.

i was making a mistake,
$ make
cannot_be_done_with_spaces_in_the_Folder_Path...

Download
https://merging.com/support/downloads#alsa-linux
make again
compiles,
but gives different errors.

the
https://github.com/bondagit/ravenna-alsa-lkm
also gives errors.

will try the others:
https://github.com/oyvv/ravenna-alsa-lkm
https://github.com/ACMILabs/alsa-ravenna-lkm
https://github.com/nicolassturmel/ravenna-alsa-lkm
https://github.com/bondagit/ravenna-als ... s67-daemon

ACMILabs is broken,
all the others give similar error:

a shame, others work ok in Win and Mac:
WormHole2,
FXMax Teleport
"VEP" Vienna Ensemble Pro 5 / 6 / 7
rtpMIDI
ipMIDI nerds.de
etc...

Network Audio & MIDI is Amazing.
