Hello all, could someone please tell me if there is an amplified connection on the ports on the back of the board or is it just amplified for the (front headphone). I just ordered a pair of Sennheiser pc360s and when the tech put my rig together, he could not get the front mic and headphones jacks to work properly with the case i picked (Bitfenix Shinobi XL). So Im hoping the rear ports are amplified as well, or else I need to get a dedicated sound card to help power the headset. Any feed back would be helpful. Thank you
