I am brand new to Cakewalk and have figured out the basics but am having a bit of trouble with headphones. I am using Cakewalk Music Creator 6 and a Behringer U204 Audio Interface with Windows 10. When I plug the headphones in to the audio interface, I am only hearing on one side of the headphones. Is this normal? If not, I am guessing one of two problems but I'd like to know which one before I go buy a new set of headphones. I have switched input to Stereo and that didn't help. Do I need headphones with a TRS plug to get both ears to work or is it something else?
