On the Asrock website it said that the Asrock x79 extreme11 motherboard has 7.1 on-board HD audio. but it appears in the picture that it only has 5.1 audio. I am planing to use this with my Razer Tiamat 7.1 and I would like someone to clarify that the motherboard has got 7.1 audio so I don't have to get a sound card.
