Re: Focusrite Scarlett Gen 3 4i4 (and others)
@geoffrey, I'll post things specific to 18i20 gen 3 to this thread instead.
Re: Focusrite Scarlett Gen 3 4i4 (and others)
Just caught back up with this thread. Guess I should post the full lsusb for Gen3 2i2:
Whats interesting from the rest of the thread is:
So the synch type seems different from the other Gen 3 devices - seems a bit odd.
Anyway device works fine recording up 192kHz, which is what I mainly use it for. But few issues, I've only been able to set speeds 44.1kHz and 192kHz, and I haven't been able to use this as an output device.
Any ideas? Is this because I don't have a kernel driver for this particular device?
Edit: Scrub that I can't set the sample speed, actually can set it to 1,2,4 times 44.1Khz or 48kHz - but only those values. Not sure what was going wrong before ....

Re: Focusrite Scarlett Gen 3 4i4 (and others)
I have an 8i6. I applied the patch to my kernel but alsamixer only shows the clock source option.
This is the patch I used I followed https://fedoraproject.org/wiki/Building ... ing_kernel and https://forum.level1techs.com/t/compile ... way/149242 to build the kernel
My kernel sources are patched.
I have the following in /etc/modprobe.d/scarlett.conf
This is my kernel version
Using the prebuilt kernel works but then DKMS won't work because I don't have the kernel source packages.

Re: Focusrite Scarlett Gen 3 4i4 (and others)
I also have an 8i6 and alsamixer is working for me. My scarlett.conf looks the same as yours. Are you sure you patched your kernel correctly? I'm using arch latest kernel, patched using the file you attached. However I removed lines 1 to 10 so that the file starts withscj643 wrote: ↑Thu Aug 06, 2020 12:11 am I have an 8i6.

Re: Focusrite Scarlett Gen 3 4i4 (and others)
Greetings! I've just recently read through this entire thread and noted as much as I could about it so I could slide in and join the conversation!
First, a brief summary: I started in Linux in November of last year with Ubuntu 18.04 as my sole OS, and have moved on through to 20.04. I've recently built a new computer on which I installed Ubuntu Studio 20.04 / XFCE / 5.4.0-45-lowlatency Kernel. I purchased a used Scarlett 18i20 in excellent condition on ebay in July and only discovered the whole proprietary audio server issue after I received it.
I'm happy to have come into this at a time where so much work has been done to make it compatible with Linux, but this poses me a challenge since I am not only still pretty darn new to Unix-style OSes (and even newer to Linux audio), but also familiarizing myself with a complex device through an OS which the manufacturer seems indifferent to if not downright hostile. I say this because when I attempted to contact Focusrite to ask some basic questions, the tech representative's tone and demeanor changed the moment I mentioned which OS I am on, and seemed determined to end the call as quickly as possible.
Since I barely installed Ubuntu Studio less than a week ago, I'm eager to help beta test the driver before I pack a bunch of data on my drive. I have not attempted to use geoffrey's driver because I remember him saying a potential incompatibility? How severe would the consequences be if the process doesn't work? Other than using modprobe I have absolutely no experience compiling a kernel.
I just wanted to mention an observation I made regarding MSD mode.
When I attempted to use USB 1.1 or 2.0, Focusrite's popup notification (in Windows 10) would inform me the device was in MSD mode. Also, Focusrite Control also would not recognize hardware attached. I had to set it to USB 3.0, and both of those problems went away. This is significant, because even though the device is USB 2.0, 3.0 had to be used for it to function properly in the VM.
Once this was fixed, I was able to toggle settings like normal in Focusrite Control (though there were two instances where the VM would stall, and/or Focusrite would suddenly no longer detect the hardware which forced me to restart the VM). I was able to configure what I needed, but there was an unfortunate drawback. Since the VM's audio playback was attempting to use Pulseaudio, I could not hear/test the effects of my configuration without first closing the VM and accessing the device in Ubuntu.
There's another issue that I'm not sure if I have a good handle on: Surround Sound
How can the 18i20 (or any other Scarlett device) be configured in Linux for Surround sound speaker setups? I use a quadraphonic 4.0 surround speaker system that I have happily used for over 20 years, but usually it's a simple matter of going into a sound options menu and telling the OS how many speakers I have. But, how to do this for a Scarlett?
On my old computer, using Ubuntu 20.04 with Gnome, using my on-board 7.1 sound card, Gnome had its own special menu for configuring speaker setups, much like Mac. Sound is routed through Pulse Audio, and it allowed me to select a speaker configuration I wanted through a drop-down menu. I could then test each speaker for sound. Ubuntu Studio with XFCE doesn't seem to have this menu, and pavucontrol doesn't either. Is there an equivalent function for XFCE?
This is what the Scarlett 18i20 3rd Gen User Guide has to say about surround sound:
Creating a Carla patchbay for Jack server reveals the number of inputs and outputs:
system > playback_1,2,3,4 would most likely be what a quad sound system would use. 5.1 surround would use 1-6, and 7.1 would use 1-8. Would this not mean that pulse_out would need a corresponding number outputs? (i.e.: front-left, front-right, rear-left, rear-right, and so on...) How would this happen? Would it need to be mapped through to the driver to pulse?
I've made this post long enough, so I'll leave it here for now. I'm hoping that geoffrey will eventually reappear in this thread so I can touch base with him and offer my help beta testing. Cheers!

I just wanted to mention an observation I made regarding MSD mode.
I did exactly this, and since I am new to VirtualBox I had to install the Expansion Pack which enables USB accessibility. While I was doing so, something peculiar happened:jhgoodwin wrote: ↑Wed Apr 08, 2020 3:12 pm FYI, for those who would use a windows virtual machine if they could, Microsoft offers development virtual machines for free which is set with a time limit.

This is what the Scarlett 18i20 3rd Gen User Guide has to say about surround sound:
This leaves me wondering how surround sound speaker configurations would be handled in Linux? Would it depend on whether I'm using Pulseaudio, ALSA, or Jack? Would it be application-by-application like Windows, or the Gnome / Mac method with a global settings menu? Moreover, does this have to do with the driver geoffrey is creating?Working with surround sound
Because the Scarlett 18i20 is equipped with ten line outputs, it is ideally suited for use when working in multichannel sound formats – LCRS, 5.1 surround or 7.1 surround, for example.
In order to route each channel to the correct output you will need to route the DAW outputs to the Line Outputs in Focusrite Control (e.g. DAW Output 1 > Line Output 1, DAW Output 2 > Line Output 2, etc.).
Windows users:
In Windows, surround sound can only be used in software supporting multichannel ASIO. In most cases this will be your DAW, and in general, DAWs capable of mixing in surround allow you to set the speaker mapping up in the DAW’s Audio Output Preferences or I/O Settings page.
Please see the User Manual (or Help files) for your DAW for guidance on setting up the outputs for surround mixing with the speaker configuration you wish to use.
Mac users:
On Macs, surround sound configuration can be done from all applications that support multichannel audio (DAWs & regular macOS Applications). To do this, go to: Applications > Utilities > Audio MIDI Setup > Scarlett 18i20 > Configure Speakers > Configuration > Select the desired configuration.

Re: Focusrite Scarlett Gen 3 4i4 (and others)
Hi,
you can add a new Sink from Pulse to Jack with 6 channels with the following:
This adds a new output for Pulse to Jack with 6 Channels with Left, Right, Center, Surround Left and Right and LFE.
Replace the channels=6 with channels=8 and you got 7.1.
Best regards!

Re: Focusrite Scarlett Gen 3 4i4 (and others)
@geoffrey What are the next steps for getting this into kernel mainline? Do you need more testers or any dev cleanup help?
Re: Focusrite Scarlett Gen 3 4i4 (and others)
Sorry for lazy question but how can I find a patch for current linux kernel (e.g. 5.8.11)? I have a Scarlett 8i6 3rd gen. I see with 5.8.11 only the clock source selection in alsamixer. I tried with Ubuntu 20.04. I've got the playback and capture with Pulseaudio and JACK to work sometimes but not systematically. The inputs in front panel seem usually to stop working when I move the USB connection from MacBook to Linux computer, the signal level led stops flashing.
Edit: I found https://github.com/geoffreybennett/scarlett-gen2.git and branch for gen3. Also realised that there's need for module options. Is it enough to get patches from this onwards and rebase them for current kernel? I need for other purpose a fresh kernel.
Edit2: There were only two easy to fix rejects. I got the alsamixer and I can toggle the front LEDs!

Re: Focusrite Scarlett Gen 3 4i4 (and others)
Is Focusrite Scarlett currently good enough to work with Laptop? I'm mostly interesting about 2nd gen and 3rd gen.
Since my old firewire laptop is too rare (more than 10 years old), I need to switch to new laptop and find a good card for rehearsals/concerts.
From Scarlett I mostly need 48 kHz sample rate and full control of the internal mixer. Had no issues with Saffire Pro 40 but firewire is DEAD, at least for laptops.

Re: Focusrite Scarlett Gen 3 4i4 (and others)
I have 1st Gen Scarletts 2i2 and 2nd Gen Scarletts 2i4. These run perfectly on my Linux notebook computer with Core i5.sadko4u wrote: ↑Wed Sep 30, 2020 3:27 pm Is Focusrite Scarlett currently good enough to work with Laptop? I'm mostly interesting about 2nd gen and 3rd gen.

Re: Focusrite Scarlett Gen 3 4i4 (and others)
Today I've started new challenge with the following hardware configuration:
- ASUS TUF Gaming FX506II based on Ryzen 7 4800H.
- Focusrite Scarlett 18i20 gen3.
- OpenSUSE Leap 15.2 distribution.
Since there's a pretty old kernel (5.3.x), I'm thinking on back-porting changes from @geoffrey's repository: https://github.com/geoffreybennett/scarlett-gen2
So the personal question to @geoffrey is: I see set of branches there:
- ASUS TUF Gaming FX506II based on Ryzen 7 4800H.
- Focusrite Scarlett 18i20 gen3.
- OpenSUSE Leap 15.2 distribution.

Re: Focusrite Scarlett Gen 3 4i4 (and others)
For openSUSE Leap 15.2 users, I've created backport of @geoffrey's driver to the 5.3.18 kernel which is currently used by openSUSE:

My Focusrite Scarlett 18i20 seems to started working. But there are couple of questions. Hope @geoffrey will be back soon to discuss them.
