RGB Music sync

[Damien19721508]

Okay so i have set up some RGB fans in my new case and connected them to my RGB header but for some reason the music sync only syncs with what plays through my front audio jack, which seems to be controlled by realtek audio manager so i figured if i could set it to play through my rear audio jack or if i could change it to play through anythi g else then i could control what my rgb lights sync with but i dont know how to tell the lights what to sync with does anyone have a solution for me ? As the issue is i dont use the front audio jack i use the rear and i use a USB headset so my music sync plays through a jack i dont use so basically my lights flash but i sit in silence because i cant make them play through another port.
