My Razer Barracuda HP1 5.1 headset arrived today but I'm having problems with it, before I send it back to OCuK I wanted to check there's no way of getting it fixed. Basically it uses a USB cable to power them then the usual minijack audio cables for the sound, I'm getting interference through them whenever there's any activity on the PC, e.g. mouse scrolling, game loading, typing etc, if I turn up the volume it'll drown the noise out but I don't really want it blaring constantly. Anyone have any ideas? Thanks.
