So I picked up a Logitech G35 a while ago and never used the surround sound feature. Now, (6 months later) I decided that I should try out the 7.1 surround sound, so I downloaded the software plugged in the headset and they showed up just fine. However, when I go to the surround sound tab and flick the physical switch on the back of the headset to turn on the surround sound, it wont turn on at all. The stereo works fine, but the surround sound won't turn on. I have tried downloading earlier versions of the software and nothing has worked. I'm using windows 8.1. I have a feeling the switch is just broken. Does anyone know anything about this or could help me?
