After installing and uninstalling Realtek audio drivers, I messed up my Headphones and now, the sounds only transmit from the speakers, and not onto my Earbuds. It only does that with voice. I have a Windows 10
tl;dr music/sounds comes out of speakers, not earbuds
Un-plug, then plug in the headphones again. It should pop up one of those realtek shitty windows saying: "Hey what did you just plugin"
If that doesn't work, its possible the default audio device was changed, just right click on the audio icon > playback devices and select them headphones
