Windows 10 Stereo Mix issue? Trying to use SPDIF and Analog Audio together!

[Squall]

So I've been goin' nuts with this for about a week.

So I recently purchased a 1000W Sony Home Theater System (BDVN-5200W) which is my main outgoing audio system. What I had before this was a Razer Leviathan.

My main audio for the Sony is connected via Optical / SPDIF and the main reason I'm keeping this one my motherboard is so I can keep the SupremeFX sound from my Motherboard

My motherboard is the ASUS Maximus VII Hero.

Now what I'm trying to do is set my old Leviathan, and use it as strict surround sound, behind me.

I was told you cannot use 2 audio channels on the same board at once so you needed to buy a sound card... so I did. I bought the ASUS Xonar DGX PCI-E 5.1 card.

I hook up the Leviathan through the black surround port on there and now here's where I'm stuck.

I updated the drivers, and all that, but now I have 2 Stereo Mixers in my Recording tab in my sounds options. One from the Realtek (my default Optical) and the Xonar.

I've been swapping around with the Listen to this Device, bull for over 3 hours and I'm NOT getting any surround sound at all when gaming.

Could someone PLEASE tell me what I'm doing wrong and please guide me through if possible?

Main Audio is Optical
Surround is Analog

My Default Audio device is set to the Realtek Digital on my Motherboard.

If you need any other info, please please ask... I really don't wanna think I wasted money here...


I've even swapped them around too, and still nothing...

While I'm on the subject, is it possible to not have Stereo Mix have an audio delay between two devices...?

Does that require a Sound Card for that to work, because it won't work regardless when I connect the Leviathan in the black rear speaker port, I get no sound from it at all.

I don't mean to bump, but... no one knows...?

I usually come to this forums cause everyone is so helpful, unlike TomsHardware where it's more helpful waiting for water to boil.

I just game off my laptop but I believe the game has to specifically support surround sound and I also don't believe a game will be able to use both sound cards.

Well I know the game supports surround sound, since I've done it with analog, but there's only 1 analog port on my Sony Home Theater system and that's being used for my PS2, and has some weird issues with some PC games.

What would getting the audio card have done for me? I was told if two seperate sound cards worked together, it would work but.. it's not.

Does the game allow you to change the output to the second sound card?

Final Fantasy XIV doesn't allow you to do that, no... But that's why I tried to use Stereo Mix but alas, that's where my problem lies... x.x
