Hi...I have no option to select separate Recording and Playback devices in my audio setup. Pic 1 is of your guy, Joe's video on I/0's. Pic 2 is my own screen shot. No matter which device I select, it doesn't give me an option. I am using a STUDIO 1810C for mics etc and a Spark 40 for guitars. As of now, I cannot track and hear a playback of another track. 3rd pic is my version of Studio One. HELP!

In Mac OS you can set a playback and recording device, whereas in Windows you simply choose a single audio device from the drop‑down list
