I have a Rampage IV Black Edition Motherboard with Supreme FX audio. I specifically asked them when I purchased it if the optical out supported 7.1 channels, I was told yes back then. Come to find out today that is not true, it is only 5.1. I just purchased an ASUS X99 Deluxe II motherboard, and come to find out today, that it too only supports 5.1 channels out on the optical and only supports 7.1 channels through analog connections. I also inquired about ASUS's Essence STX II high end sound card. Same problem, 7.1 analog, but 5.1 coaxial. The same situation is with the ASUS Strix RAID DLX, 7.1 analog and 5.1 digital. Is there any X99 motherboard by any mfg. that supports 7.1 audio out from the digital connection. And, if not, is there even a sound card available that supports 7.1 audio out from the digital connection? I use a receiver for my speaker connections and want to utilize all 7.1 channels that it supports.
How to get 7.1 audio out the coaxial or optical out on the computer?

If I used HDMI it would have to come from for example an Nvidia Graphics Card. I don't know of any audio component that has HDMI out so it would have to be a graphics card. The quality of the audio on the Graphics card is not as good as with 3rd party audio cards and motherboard manufacturers.
Well I decided to read some previous Forum posts on the subject, and the advice usually given corresponds to what you are saying, that if it's digital out from the graphics card there won't be a difference from a dedicated sound card. I do have another question if you know the answer to this also. When I check my receiver it shows "Multi Channel in 7.1" when connected to the optical out from the motherboard. Asus just told me that it should only be outputting 5.1 from the optical jack. Does this mean Asus is incorrect about their own product, or is there some other conversion of the audio going on to convert it from 5.1 to 7.1?
