Question

I got a Zenbook deluxe 3 laptop, it's more strong than a macbook pro.

Before I played with a Focusrite and everything was OKAY...

Answer 1

This question is pretty vague, but I'm going to guess that you may have expected Quantum to have an internal mixer.

You will need to open a DAW to monitor input.

Answer 2

I have both the AX8 and Quantum and they work fine together. You need to give more specific details about what you are trying to do. If using S/PDIF, the Quantum needs to be set to 48khz because that is what the AX8 supports. Analog from the AX8 works like any line level analog input to the Quantum.
