I think it's safe to say that the AVB serie (1248 / 624 / ULTRALITE)
is working for Gnu/Linux.
Hmm according to Fernando's message :
I had problems with the newer generation of Motu cards that have a
USB3 interface, so beware. Those work fine with USB2 connections but
then the I/O is restricted to 24 channels input and output
Fernando : Have you had a chance to tweak/test the bios settings
related to USB : hands off / legacy and others options that
motherboard sometimes offers ?
Don't waste your limited life span with such questions and possible
workarounds, since it's not worse the effort, assuming making music
should be your aim. Get a class compliant USB device and ignore all
those special offers, just use a modern PC + the audio interface as a
class compliant audio interface and don't use the audio devices hardware
monitoring and any additional features.
In case you did not notice this is, AFAIK, a class compliant device. It
works fine over USB2 as a class compliant device but the channel count
is limited (which might be fine, it depends on the application).
When using the USB3 transport layer (ie: connected to a USB3 port
instead of USB2), the Linux kernel has problems with the interface. I
have not had time to look at this further - I selected and I'm using the
older devices that work fine for my needs using USB2.
_Simply_ use a mixing console
for the monitoring or use software monitoring with less latency.
As usual it depends. Sometimes that is just not an option.
You need to weighing up your "available lifetime" with "computer geek
trendy" vs "the passion to make music".
Thanks for the advice. It is, and always has been, a balancing act. I
think I'm doing fine (https://ccrma.stanford.edu/~nando/).
This is (I think) a Linux kernel problem. If nobody spent time trying to
hunt down weird problems like this one we would not have Linux or this
list.
