Man, I saved a .wav file into my home folder. By typing "aplay -Dplughw:USB some-test-wave.wav" I can hear it from the output of scarlett! The device is playing!

I want to use a program called MATAA, an extension of the Octave software. I can't change devices in MATAA, because it uses the default one, wich I need that be the usb device.

I'll do now the recommendations of Torstein.

What you means with "do a git pull in linux folder"?

Perfect. That's just what's expected - good job! :)

The lsusb output hasn't changed - it just dumps what the hardware reports.

So what does "aplay -Dplughw:USB some-test-wave.wav" do? Do you hear any
sound?

You say you don't see the device in the Ubuntu "Sound" pane? That's
actually strange, because the system registered it properly.

Torstein posted another patch, which I put into my branch as well.

You could do a "git pull" in your "linux" folder, and then repeat the
steps from https://wiki.ubuntu.com/KernelTeam/GitKernelBuild, starting
at step #8. Does that help?
