Installation problem

[aloey]

I have followed the bash commands in the README. However, when I do ./scarlett-mixer hw:2 I will only see:

Device `hw:2' is not supported
Error: GUI was not initialized.
bye.

I am trying to use my Scarlett 18i8 and I am using 18.04 ubuntu.

Is this an older, 1st generation, Scarlett device that is supported by Linux?
The linux driver does not support the mixer of newer Scarlett devices yet.

Device hw:2' is not supported` either means that "hw:2" (3rd hardware soundcard, start counting at 0) is not a Scarlett device or an unsupported device

You could try

./scarlett-mixer --print-controls hw:2

That will print the soundcard's name, or simply list all devices with aplay -l or cat /proc/asound/cards

does amixer -D hw:2

@x42 I am a first timer on Linux. So I am very confused with all this.

To answer your questions,
This is Focusrite Scarlett 18i8. It is also gen 1.

./scarlett-mixer --print-controls hw:2 will still result in "No such file or directory"

aplay -l

I am not sure what you mean by "does amixer -D hw:2"
I typed that in my terminal but I just got a really big chunks of text.
