US-4x4 playing mono output from line one to two speakers?

[pseudoskorp]

I am using the US-4x4 in conjunction with Windows 10.

My DAW is Cubase 11, and I am having success recording from multiple sources.

What I am having trouble with, though, is figuring out how to get playback coming through two speakers.

Currently when I put my headphones into the headphone monitor jack on my 4x4 I only get sound through the left speaker. What setting SHOULD have have set in order to get sound coming out of both speakers when my headphones are plugged into the phones jack?

You'll need to use (2) outputs to get sound out of both the left & right, because stereo is (2) channels, not 1. So, route to #1 & #2.
