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.
