Yes, and if you refer to your mobo specs, you may find that when you implement the 5.1 or 6.1 sound option there will be a conversion of the audio in and audio out and mike in jacks. These jacks will now be
audio in = front (L/R)
audio out = back (L/R)
mike in = Center (L/R) or Center Bass
Some mobos require a jumper change to accompany this or some uses a plug conversion for center bass option. That is why you should always check the specs.
