On headphones, my Focusrite 2i4 (1st generation) is only playing through the left side. Of note, I've generally had to manually move the headphone jack slightly (could hear a little static noises doing so) to get it in stereo and it stays in stereo after that. Now, nothing has worked. It works in stereo on my main monitors, but I primarily use the headphones.
Any tips on fixing this or would I need to buy a new interface?
