Hi all, bought a rift s on saturday, didn't work when i plugged it in, orange light and black screen etc. took hours to figure out a sorta solution.
I disabled both rift s sound drivers in device manager (right click on start menu) and use computers speakers.
To use headphones from the headset I only disable the top rift s driver (see attached image). I have to unplug and plug the usb and display port back in every time I turn the computer on and when I change from pc sound and headset with headphones. Don't know if this is any help to anyone but it works for me.
