Android music pauses when using headphones

This started happening a few days ago but my phone stopped to play music (pausing) on headphones when I: 1. Screen off 2. Notification menu is pulled down 3. Opening all applications on the default stock launcher Music plays only if the music app is in foreground or if I went to the launcher and not selected anything. I am using custom rom but it stopped working on it after using it for over a month. I tried to update the rom to a newer one but it still doesn't work. Music plays fine when not using headphones and just using the speakers. Phone: Note2 ROM: temasek cm11 (http://forum.xda-developers.com/showthread.php?t=2596887) Kernel: Devil's kernel (http://forum.xda-developers.com/showthread.php?t=2239453) App: Apollo and Google music (same thing), pretty much every music application on Android
