Hi tkcomposer! Sorry I'm really late in my reply. On my side I'm able to change volumes, mixes, pads... Would you like to share your patched code so that I compare with mine? Sorry for the very late reply. Somehow I missed your message. I have since used the improvement by @sadko4u (see his pull re...

Thanks, clovis . He has contributed a lot so we'll just be patient. I had looked into that branch of the repository, and attempted to apply the same patches to my source tree, with modifications (I compared gen 2's 4i4 against its 18i20, and tried to apply the same logic to gen 3). I was able to get...

geoffrey , I tried to create scarlett2_device_info s18i20_gen3_info in mixer_scarlett_gen2.c, but it didn't work (please see the attached patch files). I figured we still need you to verify the addresses are still correct via the usb dump, which I can provide via usbmon. For example, this is what t...

@puleglot , thanks for the patch! It works well for my 18i20 3rd gen (patched over 5.7.9-arch1-1).

I assume you plan to submit this patch to the upstream, correct?

@geoffrey, I'll post things specific to 18i20 gen 3 to this thread instead.

@geoffrey,

I brought the thread specific to 18i20 gen3 here to avoid confusion.

For sound/usb/mixer_quirks.c, the IDs for 18i20:

ID 1235:8215 Focusrite-Novation Scarlett 18i20 USB

Anything else you need?

Since this thread is a top hit from Google I'm adding some info here. 18i20 Gen 3 works out of the box, with inputs/outputs available to you right away. Of course, the mixing/routing features that Geoffrey is working on (Thank you @geoffrey!!) are not available yet, but he's saying it shouldn't be l...

@Drumfix, thank you so much. I wish I had been smarter to have asked you earlier. About the AVB module: thanks! This is good news. I may come back to ask for more help on how to properly compile a kernel module. BTW, is it possible to use module parameters instead of header files? About the USB patc...

@drumfix, thanks for the clarification. That makes sense. I did put the hardware addresses in the header file, but I encountered some compilation error due to Arch having different convention for header/source locations. I had to return unit soon, so I didn't spend too much time on that; besides, I ...

My previous response didn't show up -- perhaps it was being vetted? Anyway, I want to add another piece of info -- I did get a Intel i210 Ethernet card, and compile @Drumfix's patched kernel (both onto RT and regular, on Arch) for the AVB route. It didn't work for me -- Ultralite AVB switched itself...

About the exchange they had offered, it turned out they had a BIOS change that broke the Linux support, even before the ES version. See the response (they responded after two weeks): Please note, not all UltraLite AVB (non-ES) units will work on Linux, it turns out. The change that unintentionally b...

HI all, I got MOTU UltraLite AVB a few weeks ago and went through some very frustrating experiences; I'm planning to return the unit . Hopefully this information will help somebody else make their decision. Right out of the box, my unit has the channel hopping problem (therefore LTC doesn't work for...
