Ah Scarlett.. my FireWire tanked after an update and had to use the headphone jack instead. 

Good luck in getting it figured out!

Yes Youtube videos play through my earphones plugged in the interface. Just tried to record something on my new Imac, same result. :(

I assume you also set the audio output to Scarlett in your general preferences? Do YouTube videos play out through the interface?

Hello! I have sent my Macbook pro for repair. When I got it back, Mojave was now installed. Now I can't seem to be able to record with my Scarlett Focusrite 2i2! Logic Pro recognizes it, there is audio signal on the Focusrite but when I press record, there is nothing appearing on the track. What gives? Thanks in advance!
