New User can only hear vocals, not guitars

[Dimitri Muskens]

So you both tried your instrument in the - functional - 'other' channel (the one that does produce sound with a mic) and no dice?

Couple obvious ones (sorry);
Did you adjust the input gain on your 2i2 for your guitars?
Is the 2i2 registering input from your instruments - so does the ring/button light up?

^If so^, is JK registering input on your instrument channel?
Is it real low by chance?
Did the channel accidentally get muted in JK? (easy to do/overlook)

Do you use Focusrite Control (2)?

>DM should be switched off btw. Like when using a daw, you listen to the output from the app/program - the mix.
So when not 'in a session' there should be no sound from either channel.
