Laptop Model: Predator PT515-51
Sound Card: Realtek Audio - NVIDIA
I have a Creative SBS 5.1 (560) surround sound system with the typical three, 3.5mm plugs. Only one small problem, actually three, my laptop, does not have the three analog outputs from the sound card. It can support 5.1 and even 7.1, but I don't know how to interface with that if I only have one analog out for headphones / speakers in run of the mill stereo.
I've been looking at a StarTech 7.1 USB Audio Adapter External Sound Card, but the reviews are all over the place. I have found a few more, but I have my doubts. Another thing that crossed my mind was, since these devices have some type of sound card in them, would that override mien and degrade the sound quality?
I would imagine that this is not a unique problem. How do you have a fancy sound card that can support 7.1 surround sound, which needs four outputs, yet there is no way to interface with it!?

I'm wondering if I should just go with a 7.1 sound bar
OR
there is nothing to worry about and I should just get the converter under the assumption that it does not degrade the sound.
Any input or information on this would be appreciated. Keep in mind, I don't have a CD / DVD driver, so if you recommend something that comes with a disc for drivers, tell me if I can download them online or not.
One thing is for sure, Acer could put more holes on their laptops.
