GX740 - Anyone get two TRUE separate audio streams out Headphones and LINE OUT?

Question

Hoping for an update on this. I asked MSI via their support section and wow... what a FAIL that was:

Do you have new specific drivers that allow TRUE 4 channel output? 2 out the headphones and 2 separate out the LINE OUT as implied by the design? I've tried everything and it doesn't work.
I've tried ASIO4YOU drivers - doesn't work.
I've tried every RealTek driver out there - nothing.
Yes, I've set the RealTek driver to do multiple out but it sends the audio out the HDMI port, NOT THE LINE!
I know this can be done cause you can set the REALTEK for 7.1 and you get separate streams out the headphones and line-out ports!
Please - you've sold a laptop with "Headphone Out" and "Line Out" yet it fails to actually do that - NEW DRIVERS PLEASE?

Dear Customer,
Please go to msi global website to download the audio driver,then install it.

Needless to say, that did nothing. In fact, I can't understand how I could of received such an answer given it made no sense what-so-ever. Download the driver that came with it? One that's now almost a year old?
Regardless... I've tried that one. I've tried the latest RealTek drivers. I've tried a multitude of ASIO drivers. NOTHING WORKS. Yes, I've set the RealTek to send TWO SEPARATE STREAMS. That does NOTHING. The only thing I've been able to ascertain is that you can send one stream out the headphone/line out (same thing) AND one out the HD port which is useless.
Here's the pain in the ass: If you go to the RealTek setup and change it to 7.1 and hit TEST, you DO hear separate output out the HEADPHONE JACK and the THIRD Audio Out jack which is the side fills so I know this laptop CAN spit audio out two separate outputs sitting on the side of the computer.
Why do I want to do this:
Simple. I'm lugging around an external audio interface for DJing and it's a pain. I'd rather just tap the headphones out for, well, headphones and send the line out or that third audio output to the DJ mixer. Done! I've tried MIXMEISTER, VIRTUAL DJ, NOTHING WORKS! I can select various strangely named outputs insinuating speaker out, speaker out + 1, etc... but no... it doesn't work at all...
Sooooooooo... has ANYONE been able to get this to work? I'd love to know...

Yea Stu... been through this part... Playback devices show the typical:
1. Speakers (Realtek) -> Plays on ext. speakers but sounds like just treble. Headphone Out plays this stream.
2. RealTek HD Audio 2nd output -> Plays on ext. speakers but sounds like bass/mids. No treble. NO OUTPUT PLAYS THIS. Plug anything in and sound from the speakers just shuts off
3. Realtek HDMI Output (Not selectable)
4. Realtek Digital Output (Not selectable)
So yea, it seems right out of the box there is a problem with the sound on this unit. Choosing speakers sounds like crap (no mid/bass) and choosing HD Audio 2nd output sounds like crap (all mid/bass no treble).
There is no discrete dual audio out the jacks.
HOWEVER - Go choose 7.1 from the realtek setup and do a test. Well what do you know, DISCRETE 2ND AUDIO OUTPUT OUT THE HEADPHONE JACK AND THE 3RD OUTPUT JACK OF THE 4 IN A ROW. This PROVES you can have two discrete stereo audio streams coming out the output jacks. Just need someone to write the driver for it.
Here's the thing. This laptop HAS 4 1/8" JACKS. SEE:
Here's what the manual says about the output jacks:
