Dear Linux audio people,
I have a Scarlett 18i20 3rd Gen interface which I'm trying to use on a
recent Samsung laptop with Ubuntu 19.04.
The 3rd gen devices are apparently shipped in non-functional "MSD" mode,
so I registered and activated the device using Windows 10 following the
instructions on the Focusrite website. Tested it there with Ableton Live
Lite (provided via registration of the device) and also Ardour. It works
fine. To get it to work on Ardour it was necessary to use the ASIO
driver in the Ardour audio configuration. I had removed ASIO4ALL before
installing the Focusrite/Scarlett software as suggested, so perhaps this
driver came with Focusrite install.
Now with the device apparently configured and the routing done in
Windows using the Focusrite Control software (i thinks that's the name,
I had selected output channels 1 and 2 to connect with the
monitors/headphone jack), I returned to Linux. The Scarlett device is
detected by lsusb, qjackctl and pavucontrol. Jack runs with no errors
when the Scarlett is selected as the i/o device and all the correct
channels appear in the Connect window. No sound however is heard through
the phone jack, nor if i plug the phones directly in to the output jacks
at the back. I tested using VLC configured for Jack output and also with
pd -jack.
With jack turned off and with VLC audio out set to pulsaudio, I set the
Scarlett 18i20 as the preferred device in pavucontrol. With VLC playing
the output VU meter for the Scarlett is active in pavucontrol but there
is still no sound coming out of the device itself.
Has anyone managed to get a 3rd generation Scarlett to work on Linux?
Can anyone suggest please what I can do?
Thanks!
Iain
PS. i did see an unresolved thread on this list last year about a 3rd
gen Scarlett. I'll send a message to the author to see if the problem
was fixed.

Adding to that:
If in Windows, I plug in a mic into channel 1 and turn up the input
gain, the input LEDs respond as they should to incoming sound. I can
also in the Focusrite Control sodtware, map the input directly to the
monitor so that I I can hear it in the headphones. If I then reboot the
laptop, the LED and routing continue to function until the machine loads
the Grub system boot page, whereupon the LED stops functioning and the
monitoring of the mic also stops. The mic channel remains unresponsive
when Linux is booted. This is a bit worrying as I had read for earlier
generations that the control routing set in Windows is remembered by the
Scarlett once in Linux (and presumably after switching the box on and off).
The F6 button in alsamixer shows "Scarlett 18i20 USB", however once
selected, for capture/input, it says something to the effect of: this
device has no input/capture controller. For reproduction/playback it
lists only S/PDIF but with no fade controler.
Hope someone can help!

and another observation:
It occurred to me to boot into Windows with the Scarlett attached and
then pull out the USB before shutting down Windows. The Scarlett seems
to hold its levels and the LEDs continue to respond to mic input once
detached. I tried then booting into Linux, the levels hold on the
Scarlett until the USB is plugged back in again whereupon the input
level falls to zero and/or becomes unresponsive. Perhaps it's some sort
of speaker protection thing.... Looks like the device consults fader
values stored on the computer on USB-connect, but with no such values
available, zeros the device. Just guessing.

The thread is about the 2nd Gen, but there is a comment on how to get the 3rd Gen. out of
the "MSD" mode:
FWIW, the manual says you can take it out of MSD mode without running FC:
"Initially, when in MSD mode, the interface will function at sample rates up to
48 kHz."
"In order to force your Scarlett 18i20 out of MSD mode without first registering
it,
hold down the 1-4 48V button while disconnecting and reconnecting the USB cable, and
then continue to hold the button down for a further five seconds."
Good luck,
best regards,
Peter

Thanks Peter. I think I already got it out of MSD mode in Windows and
it's working well there in Pd, Ardour, SuperCollider, etc. I tried the
below just now in Linux but it didn't help, unfortunately.

On the way to a solution:
The Scarlett is a USB 2.0 device. The USB ports on my laptop are 3.0. I
tried the Scarlet on my desktop, first using the blue port (USB 3.0) and
had no success. Later trying a non-coloured port (2.0?)and not before
re-configuring the Scarlett in Windows (ie. simple connecting it), I got
audio in and out to work. There are some audio glitches at both
conservative and short latencies in Jack, but i'll worry about that later.
Can someone suggest please what I can do to get the USB 3.0 ports on the
laptop to work with the USB 2.0 Scarlett? I checked the Bios and there
doesn't seem to be a way to downgrade any of the ports. A software
solution? I'm running Ubuntu 19.04.
Thanks,
Iain

Have you checked the laptop's bios? It's a bit of a long shot, but USB2 might
be disabled.
FWIW, I've had trouble with laptops and USB3 for audio but fortunately they've
had USB2 ones as well which worked fine.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.

Thanks, no it's not and it's actually the same laptop running Windows
which has no problems. I check for errors in dmesg... Both my desktop
and laptop have Ubuntu 19.04 and perhaps it's a system issue
