Well, actually I totally forgot that windows doesn't use class compliant mode, but macOS does, right?

wrl's patch doesn't work for me, as well.

Hi,
How is it going so far?
Do you need any help?

That patch is aimed at fixing the channel drifting issue and should in theory be applicable to MOTU 828ES as well as Ultralite AVB devices.

Please note: the patch does not (yet) provide a stable solution on all devices. It may or may not work on your device. The purpose of this guide is to help more people test it on their setups in the hope that we can detect similarities between systems that do work and those that don't.

Further note: this guide is built on my own approach, which is Ubuntu based. Further I'm assuming that your system is already configured with the appropriate build tools (gcc compiler, make etc.). Furthermore: you carry all risks by yourself. I'm not responsible for any damage caused by following this recipe.

Hello, Thank you all for the fight with the driver for the Motu Ultralite AVB (es) under Linux. I cannot boot in the next-kernel with the steps from user shellwalker.
Error :

Code: Select all

dracut-initqueue: Warning: dracut-initqueue timeout - starting timout script
....
dracut-initqueue: Warning: could not boot.
Under opensuse tumbleweed, i don´t know how i can install the patch to test the driver under opensuse.

Is there a way to load the snd-usb driver per Linux kernel modules and e.g. modprobe ?

Sorry for my bad english. I am a user and a rookie in Kernelpatching

I will install ubuntu on my old desktop-pc and will test the patch again. :roll:

I gain that the file bio.h is missing on your system.

A quick google-search shows that the open ssl development package is missing your system.
If I understood correctly, you are using OpenSuse, whose package system I'm not familiar with. But I'm sure you'll be able to find out how to install the libssl-devel package (or whatever it is called on SuSE).

Sorry I can't help you here. Never used Cadence b4 and I don't have much experience with jack either. I use Ardour for my tests.
At least it seems that the MOTU device as such has been somehow recognized by the system, otherwise it would not show up in the logs, right?
Just a thought: could it be that some other application is competing with the device access?

Hi LinMusicians,
I own a good working 828es and I'm going to buy a Ultralite AVB or a 624 AVB with a switch. I'm using the first firmware on AVL-MX or Kubuntu 20.04. I use to wait the turning on of the interface, then I turn on the laptop (Acer Nitro 5). I can do some tests but I need to know exactly what you need to know...

Hi buonamorte,
in a nut-shell here's the current status:
  • We are fighting the so-called channel drifting issue under Class Compliant mode - i.e. the interface does work somehow, but the outgoing signal sometimes ceases to be heard on the assigned channel, but reappears, if at all, on some other channel (and may also for some time sound distorted).
  • @drumfix provided something for the Ultralite AVB (though I'm not sure were to find that, and I've not tried it out myself on my 828ES) and it seems to require an Intel i210 nic and uses the "Windows USB" mode instead of the class compliant mode. Someone please correct me if I got it all wrong...!! ;-)
  • As far as I could tell from the foregoing discussions, @drumfix' change actually did not work for some that did try it out.
  • My understanding of the discussions so far is that the issue may be related to a bad or missing implementation in the linux kernel for supporting USB "implicit feedback mode" (whatever that is...) which MOTU appears to have activated in later firmware version.
  • @wrl had a new idea and provided a corresponding patch which appeared to work on his system quite reliably.
  • But @wrl's patch did not work on my system and also does not on work for @root2 either. Not sure what the testing results for @Musinux were.
  • @wrl said he has another idea (viewtopic.php?p=128041#p128041), but we've not seen an update on this yet. Keeping our fingers crossed ;-)
Do you happen to have kernel dev experience and/or USB protocol expertise? If yes, then it would be great if you could jump in and help debug/fix stuff.
Of course simply testing and providing feedback on your results is also appreciated!
Testing instructions for @wrl's "first" approach can be found here: viewtopic.php?p=127891#p127891
I've not seen comprehensive step-by-step testing instructions for drumfix' approach. I guess for that you'll have to read through the whole thread and gather all pieces together. But it may be worth it (and if/while you are at it, maybe you could even create that comprehensive how-to-guide for the drumfix approach? :P )

Consider buying a Presonus avb switch instead of the one Motu makes. It is much more rigid than the Motu.

Yes We NEED an comprehensible (in german : nachvollziehbarer) NEW STEP-By-STEP- Way.

Requirement for Testing:

A) Base System : New 5.11 Kernel with an Easy-To-Patch-Mode (USB Linux System (Pendrive) where excellent; nobody wont kill the own running system)
B) Same Informationsystems (e.g. dsmeg, Alsa, Journal -d etc...) about Hardwarere recognation, Erros and Results ....
C) Cross-Connection to other "Construction sites" in these forum (e.g. Moti828es, and other Devices witch similar Problem ( e.g. implicit feedback)
D) A general "Audio-Test-Benchmark", with check the Quality , Stability , Use of Channels and Midi, Soundserver/ Applikations (Alsa, Pulse, Jack)
E) then compatibility with other Linux-derivatives / Distros
F) a general Feedback Information of succees or defeat

Hi @shellwalker , @ahellquist @stean . Thank you all for your replies!

I don't have so much technical experience on usb but I can surely try this stuff, give info or write an how to.

The big question, for me, is that my 828es works great with the first firmware and waiting for a complete startup before turning on the laptop.

After 7-8 hours, sometimes, the sound begins to do something strange, but I can save and restart and everything is fine..

So, if I've understood, you with the 828es are using a newer firmware, right?

After 7-8 hours, sometimes, the sound begins to do something strange, but I can save and restart and everything is fine..

So, if I've understood, you with the 828es are using a newer firmware, right?
My unit came with v1.3.4+172 (Release Date 2018-08-01) pre-installed. That showed the drifting issue.
I've upgraded to v1.3.5+181 (Release Date 2019-05-13) which also shows the drifting issue.
Check at MOTU to see details about your firmware version here: https://motu.com/techsupport/technotes/ ... echangelog

I would guess that the strange sound you hear after 7-8 hours may be the drifting issue as well, however with some mid-term stability....

Hi @shellwalker ,
I'm using this: v1.3.2+59 (Release Date 2017-10-20)
The 7/8 hours problem happens only sometimes, usually it works out of the box...
Ah, no way to use the touch console, obviously...but all other stuff works, also the adat port (with an audient asp800)
I'm going to make some test as soon as possible!
