Question [Q] after official update to kitkat, problem with headphones

Hi everyone,

Iīm very desprite right now, because I got the kitkat update yeasterday and after it installed, when I connect my headphones, you can hear really wierd and loud background sound(my translator sais, it is called rusting noise). But not all the time, just when you listen to music/video/game/nottification anytime, the sound starts to play, the loud and wierd background sound occure. I tried the original headphones from LG and everything ist fine, but I have been using mine for a half year now and no problems have ever appierd. The headphones work with other devices just fine. I did factory reset, didnīt help either. What should I do ?
