alienware audio, wave maxx pro

ok  so it said I have the realtek 7.1 hd sound built in the mother board, but I have no sound manager from realtek, only pops up this alien ware audio in which has no controls for 7.1 sound, it says I have nothing plugged in, but I use a sdpif/toslink from the system to my Kenwood home theater system which has 7 speakers. the sound manager only gives the option for two channel stereo. if I go to tell alien ware audio to reset it, blue screens. I have uninstalled and reinstalled drivers, ran all the dell stuff, nothing changes. I wish I could install my ht claro sound card, at least it worked and I could tailor the sound to my system and have dts dobly prologic,neo plx etc. and getting answer to this problem is like pulling teeth from a shark. about ready to uninstall all this dell alien ware stuff and run straight drivers. I have built my own systems for years, this is the first time I bought a system from a company, I am about ready to give it back and just build me a new system, at least I can get to the bio screen and set it up, this thing you cant get to it either from f2 or from windows 8.1, it only gives you a black screen, nada, and yes I am aware if the fast boot feature. If you have an answer to fixing this sound manager gui I would love to hear it, thank you for your time.
