Recently, strange things have been happening to the "phones" output of my UX1. When i plug in either of my headphone sets, the sound is very flat and distorted. Also, while working on any DAW program, the volume levels on tracks do not respond to what I actually hear and all the effects distort the sound even more. None of these issues have place when i use the speakers instead of headphones, also if I plug them into the phones output using a jack/rca adapter. I've also changed the 6,3/3,5 jack adapter i'm using, to no effect. I noticed that the sound is ok, but much too quiet when i plug the jack in only partially. Does anyone happen to know what this is?
