I just got the Barracuda Headset and Soundcard combonation, I have installed the soundcard and plugged the headset in directly. While the front speakers work fine the Rear and Center speakers do not work at all. I have turned the volume on them to max on the control device connected to the headset and turned the Front speakers to mute and there's no sound coming from rear or center. I've selected HD-DAI as the setting in the Razer control panel and all the volume controls seem to indicate that I should be hearing sound, but I'm not. Are these faulty speakers and I should therefore ask for a trade in or is there something I'm doing wrong.
