im having a problem with the 7.1 surround sound. I just bought a 7.1 headset and got it all plugged in, test was going perfect until it hit the sub. The sub is definitely not working properly. Went to youtube and looked up a basetest and used my actual 7.1 surround sound system hooked up to an hdmi port on my GPU to make sure the song has wicked bass,it did, when i switched over to the head set there was none. please help
