I'm new to the forums and also new to pc audio in general. I have a Asus Maximus VI formula in my pc and an Astro A50 wireless headset. I cant for the life of me figure out how to get the 7.1 surround sound to work. I started looking into buying a different headset for my pc and leaving the astro for my console and I found the sennheiser PC 360 and PC 363D. I couldn't figure out if the 360 offered surround sound or not so if it doesn't id probably want to choose the 363D. But anyway what should I do to have a good headset running 7.1 surround sound? I also don't know much about external DAC's if that would solve my problem or not.
