I recently purchased a T4S and L1 Pro 16. Love them both, and I've been able to connect my mixer to my monitor and gotten a good mix on it when it is plugged into one of main outputs. However, I don't have any control over the monitor from the mixer when it's plugged into one of these two. There is no sound when I plug it into either one of the aux outs, and obviously no way to control it.
I've gone through both of the below articles and it seems like I'm doing everything right. It seems like the aux outputs just aren't working or something. Any help would be much appreciated!
