More aboutside headphone working
If this is a desktop computer, are you using the sound output socket at the rear of the computer (direct to the motherboard) or a front panel extension ? Have you tried connecting a different pair of headphones or amplified speakers ?
i dont have speakers, i put it direct to the motherboard, and i used an earphone it didn't work on 3d sounds or how they call it ....
i reinstalled the drive and now it's ok, thanks for help
