Komplete Audio2 , Mac mini M1, I have output from computer, but can't mix in from Inst/Line in.
It's a little tricky to understand what you mean. So you're plugging your bluray player to the inputs of the soundcard and would like to hear it on the speakers? You need a DAW or an audio router to monitor the input on the main output (connected to the speakers).

You can use https://www.rogueamoeba.com/loopback/ for example.
