I have used Ultra Ultralite AVB (not 624 AVB) to record electric bass directly to Ardour and I have also recorded vocals but then I routed the voice trough the internal mixer to let the vocalist adjust the monitoring from Ardour and have built in DSP reverb for better experience. Have not had any issues with routing or jackd or the onboard stuff except the iPad application sometimes not rendering the mixer/router pages correctly.

I am running kxstudio (ubuntu 14.04 with rt-kernel and kxstudio packages)

I have a Debian 7 box that I can check with my AVB stuff but both my cards are the classic MOTU Ultralite AVB.

If I can check anything more, I gladly will.

Best regards, Anders

Could anyone working with the MOTU ultralite confirm that they have routing from analog inputs to the computer working? I can see signal showing up in the routing matrix and device page, and the device shows up as intended with 18 channels of input in JACK / ALSA, but I don't get any signal, even though I routed 6 analog input channels to "To Computer 1" through "To Compute 6". Really puzzled ... everything suggests that this should just work....

The linked product is a rj45 splitter that is very usable for running two Ethernet connections thru a single cable but you need one of these at both endpoints and this has nothing to do with my use case. I know that a switch is the solution and was only stating the limitation gnu Linux users will face because of the missing control link.

I am quite happy with the product and I usually only need one card connected to my laptop and the things are just great as for the rest of gnu AVB users. It was only a heads up for the issue.

I hope that we in the future will have access without need for the AVB switch, both for cost effectiveness and reduced complexity.

Hello.

For me there is no confusion here.

Motu AVB's cards serie is not - officially - supported by MOTU for Gnu/Linux. Even without the «Linux» stamp on it from MOTU it's the more advanced card you can control without headache under Gnu/Linux.

The feature you talk about is for proprietary Operating system with Motu's drivers - with some limitations.

Either you bought the wrong cards, or using the wrong operating system for your need - it's only a guess.

The AVB switch *is* your solution.

Or you can try, the kernel module something like : CONFIG_USB_NET_* and try different devices under to see if your log show something when you plug any of your MOTU cards...

Or you can try something like this :

sorry don't know the name in English...

Let us know the result....





All the best.

There is confusion for sure.

if I link my two Motu ultralite AVB cards together by using the two
AVB ethernet sockets and a Cat5 or Cat6 cable. I have used all
ethernet connectors available and the AVB devices can talk to each
other but no other networking is available. If I point a browser to
any of the ip's of those boxes i will not get an answer since there is
no possible route to those cards that only have a link between them.
The cards have no built in wifi or extra ethernet jack.. How could I
possibly connect to them except by usb and Class Compliant Audio
connection which does not give me the extra IP over USB that the
windows/osx driver provides...

I have never said anything about AVB over USB but only mentioned the
missing linux link which is the possibility to access the http web gui
trough the USB (or for cards with Thunderbolt) driver provided ip-link
(for control only)

As I tried to explain. Linux users must have a AVB compliant switch to
get a network link to be able to manage Linked AVB devices OR have
windows/osx boxes connected via USB/Thunderbolt to one of the AVB
devices.

Trust me, I am not confused but only stating the obvious that linking
to cards with just a cable will create an isolated AVB cluster that
will not be manageable from linux computers until someone figures out
how to write a driver to get the IP-over USB passthru to work.
