Alienware m17x r4 help

Hey, relatively new to this whole thing but understand the basics. Just trying to get some help getting up and running

I have a copy of yosemite zone, as well as sierra zone and both kinda work to a certain extent. I cant get sound on both of them, the ALC sound codec it uses doesnt seem to be available for hackintosh (ALC3661). I have a USB wifi card that has a 'Azurewave aw-nu137' inside and is rocking an atheros chipset but idk what specific model.

So yeah, if anyone has any advice, or suggestions as to what version of macOS would be best, what kexts i should be using,if it'd be better using custom distros or if i should get my own copy or whatever, it'd be greatly appreciated, thanks for reading!
