Hi ManoMatt, sorry to hear that you are having issues with you Beats Audio. Unfortunately no driver is available at this time for the Beats Audio and Windows 8.1. I suggest that you do a System Recovery back to your original operating system. Sorry for the inconvenience on this matter.

Thanks for your time.
