Default [Q] Jabra Sport Corded mic and button are not working

Hello,

Bought a Jabra Sport Corded to use with my Xcover 2 (Rom: 10.2-20140204-UNOFFICIAL-skomer) and made it work using Jays headset controller. Evertying worked fine.

After a couple of hours I tried to test the mic and buttons again and it didn't work. The headset is recognized by the phone (it is playing music and I can adjust the volume), but the mic and button aren't working. Already tried different headsetcontrol apps and have tried resetting the phone but the problem stil occurs.

Does anyone know how I can get the mic and button working again? Any help is appreciated.
