Yes, there is a GUI planned, and it's almost ready to share! Here's what it's looking like with a Gen 3 18i20:

Stay tuned!

Will this be able to set pad/inst/line, or is this possible already? Also will this support panning channels like in focusrite control, because I'd like to monitor my digitakt in stereo but since both outputs are mono and centered on the device I can't monitor in stereo.

I'm currently working on LSP Plugins 1.2.0 release. When I'll have time, I'll get back to Scarlett driver and send many additions to it related to the control of internal state of the device.

This looks so great! Let me know if you want to have a tester at hand for this, I'll be happy to help.

I also take the occasion to state a big THANK YOU for working on integrating the drivers into the Linux kernel. It's really appreciated.

Cheers!

Hi, I tried out the Gen 3 4i4 support on a custom-built kernel back in May 2021, and it worked great. After leaving my 4i4 in a sad corner for several months I decided to pick it back up again, and I was pleasantly surprised to discover that the Gen 3 driver has been merged as of 5.14 - congrats!

However, when I run the following command on 5.14.8 (Arch Linux stock kernel):

Code: Select all

pw-jack jack_lsp | grep Scarlett

I can see that there are now only 3 recording channels advertised on my system:

Scarlett 4i4 USB Analog Surround 2.1:capture_FL
Scarlett 4i4 USB Analog Surround 2.1:capture_FR
Scarlett 4i4 USB Analog Surround 2.1:capture_LFE
Scarlett 4i4 USB Analog Surround 4.0:playback_FL
Scarlett 4i4 USB Analog Surround 4.0 Monitor:monitor_FL
Scarlett 4i4 USB Analog Surround 4.0:playback_FR
Scarlett 4i4 USB Analog Surround 4.0 Monitor:monitor_FR
Scarlett 4i4 USB Analog Surround 4.0:playback_RL
Scarlett 4i4 USB Analog Surround 4.0 Monitor:monitor_RL
Scarlett 4i4 USB Analog Surround 4.0:playback_RR
Scarlett 4i4 USB Analog Surround 4.0 Monitor:monitor_RR
Midi-Bridge:Scarlett 4i4 USB:(capture_0) Scarlett 4i4 USB MIDI 1
Midi-Bridge:Scarlett 4i4 USB:(playback_0) Scarlett 4i4 USB MIDI 1

Previously (in May 2021 on a custom-built kernel), I would have six recording channels available.

This means, for example, that if I run audacity with pw-jack audacity, use the JACK driver and select the 4i4, I can only record three channels, and not the expected six channels that the 4i4 supports.

If I run alsamixer, I can see the configuration for all six channels PCM 01 to PCM 06 that I expect (I have set them to record Analogue 1, Analogue 2, Mix E, Mix F, Mix A, Mix B in my setup), and in the dmesg I can see "Product: Scarlett 4i4 USB" and "Focusrite Scarlett Gen 2/3 Mixer Driver enabled pid=0x8212", so I am pretty sure the kernel driver has correctly detected my 4i4.

Is this a bug with the kernel driver that causes me to only see three recording channels through ALSA/Pipewire, or could it be something to do with my Pipewire userland?

EDIT: I figured it out - I had forgotten to select "Pro Audio" as the configuration for the audio device in pavucontrol. After selecting this, all 6 recording channels are available. Thanks again for the amazing work on this driver!

I'm still learning about the kernel/distrubutions ...

Does anyone know if all the work on the focusrite... is in the Arch-Zen 5.14.14 ?

Or would I need to download/install the kernel from geoffreybennett's git ?

Thinking about purchasing a focusrite for testing.

Thanks!

FWIW, I am running Debian 11 with the latest Debian 5.14 backports kernel.

Linux - 5.14.0-0.bpo.2-amd64 #1 SMP Debian 5.14.9-2~bpo11+1 (2021-10-10) x86_64 GNU/Linux

After adding the /etc/modprobe.d/scarlett.conf file and rebooting, the new alsamixer options showed up.

Trying to test it out with a Scarlett 8i6 Gen 3 now.

Geoffrey,

First and foremost, thank you and all who have contributed to this project.

Here is my initial Feedback testing with a Gen 3 Scarlett 8i6.

The CAPTURE [F4] screen's "Analogue [1-N]" labels get truncated making the first 6 entries appear to all be set to the same value "Analogue".

Maybe "Analogue" could be abbreviated, or the "N" could be placed first, or line-wrap to 2 rows, or a combination to show the overall distinctions ? Similar ambiguous truncated display issues appear with other options.

Update: "Clock Source" "S/PDIF" is working (LOCKED) on the 8i6 for sample rates [44.1-176.4]kHz.

Thanks much !!!

Debian 11-64 bit
Kernel: Linux - 5.14.0-0.bpo.2-amd64 #1 SMP Debian 5.14.9-2~bpo11+1 (2021-10-10) x86_64 GNU/Linux

@geoffrey I've been doing my research / planning on converting my DAW workstation to Linux and came across this thread. I saw your post back in August about your patch bay GUI being "almost ready." Is it ready yet? If you need testers, I volunteer as tribute.

Hi, @geoffrey. Thanks so much for all the work on this driver.

I'm on Fedora 35 with a kernel 5.14.14-300.fc35.x86_64+debug. I tried to enable the driver (I have a Scarlett 8i6) and I'm seeing frequent driver errors on my log:

Code: Select all

[    9.316002] usb 1-1: Focusrite Scarlett Gen 2/3 Mixer Driver enabled pid=0x8213
[    9.323472] usb 1-1: Scarlett Gen 2/3 USB request result cmd 2001 was -71
[    9.323488] usb 1-1: Error initialising Scarlett Mixer Driver: -22
[    9.323860] snd-usb-audio: probe of 1-1:1.0 failed with error -22

It doesn't happen all the time (after a few unplugs / re-plugs then it starts working, and audio outputs are detected by pulseaudio once I restart wireplumber with `systemctl --user restart wireplumber`). I'm not sure if it's known, but I figured I'd mention it since I don't see it reported here. Let me know if I can help debug.

The other thing I see is that analog inputs are not showing up in the GNOME settings, but I believe that's probably an issue with GNOME looking at the journal: https://gist.github.com/emilio/778903b7 ... 8d5542690e

So, I'm trying to get capture and output working simultaneously with pipewire/wireplumber.

It seems that I need to specify a very small "api.alsa.period-size" (explained here: https://gitlab.freedesktop.org/pipewire ... properties and also a test example is given).

When I set a small period-size, it seems I can no longer output to the device. I have tried input-side-only period tweaks but they don't seem to work.
I'm wondering if anyone has any suggestions on how I can fix this - I would really like to get input capture working in pipewire, and it seems this is the key).

I'm running ubuntu 20.04 with last prebuilld 5.14.0 packages on laptop with intel hdaudio that I couldn't disable in UEFI
dmesg seems alright

I do have two devices in pulse Scarlett USB and Scarlet USB (S/PDIF)
I have 3.5 speakers connected to the headphones on scarlet solo v3 with 6.35 to 3.5. And in Windows I could all sound goes through those speakers.
However in Ubuntu sound goes only through build in laptop speakers (tried both Scarlett USB and Scarlet USB (S/PDIF)), even though I hear loud noise from speakers when connect those to headphones on solo.
Please, help how I could make sound go through the speakers.

In

Code: Select all

alsamixer -cUSB

output I see only MSD Mode

UPD Fixed the issue with changing pulse with pipewire https://askubuntu.com/questions/1339765 ... untu-20-04
In deadbeef I was able to play through the speakers selecting alsa and Scarlet USB (Deafult Device), but to actually enable that system-wise without hassle, switching to the pipewire did helped, but i guess I also could change output device in pulse config manually (didn't tried through)

I have been running my kernel with this patch enabled for about a month or two and I didn't notice anything weird. I am using it with a Scarlett 18i20 MK3 with a custom mix.

My kernel version is 5.15.7-1-MANJARO.

Changing the mixer settings via alsamixer also seems to work but of course it would be more user friendly with the GUI application.

Hi all! In this stream we will improve the code for the Linux Kernel driver of Focusrite Scarlett audio interface series.
The stream will happen on friday, 7th jan, 21:00 GMT
