1st...im wowed that i still have my account and can still acces it, its been a while since i'v enter winmatrix or even logged in or even, made a post...but as usual, my post are because somethings wrong
2nd, earlier this year i bought a mobil workstation, to be exact, MSI WT60 3K disp, since what i do is mostly use AE, 3DsMAX and other stuff, plus i am a gamer and i know that quadro cards aren't meant to be used like the geforces but hey, if it runs GTAV at 1080p with mostly all on high then fudge it, im gonna fudging play it 
so heres the deal, this machine came with win7 and all the other goodies and not so goodies as most laptops, pc's come with, unless u start from zero...so i left it as it is and stuck with 7....until 2 weeks ago that i could upgrade for W10 (YEAH), need a new GUI and something that looked newer, i have nothing against 7 just that its not my cup of tea...so i upgraded, at first (and i dont want to brag) but thing didi look that sharp at 3k resolution, i lowered the text and other stuff that u can u in w10 (why on earth would it be at 200 magnification, i dont know) so i dropped it down to 150 and it seems ok, all software, sorry, "APPS" (boggus) work fine and even game run smooth like before and here is where my problem comes....this machine has Sound Blaster Cinema and Dynaudio Premium Speakers w/ Subwoofer, meaning that by default i have 5.1 (not sure about 7.1 and dont care much since my HT is 5.1) sound, so, when i was in w7 and played with the sounds and speakers, i could heard all of them on the test or one by one, now...i only get sound from left and right...iv search for a fix/solution/etc and seem that many are haviing this problem but here is where my problem differs...most of them said that when they try the test tone or click on an individual speaker, they get an error, In my case i dont, in fact, i can change from stereo to quad to 5.1 to 7.1 but only sound comes from left and right, if a play the test tone or click the other choice (center, rr, rl, sw) i do not get sound but i dont get an error neither and as a matter of fact, if i have volumen mixer open and click on the other speakers that dont make a sound, it registeres as it would make a sound, the green bar goes up as if sound is coming out of a speaker...im really liking w10 but this sound problem just fudges me all over and cant stand it....its realtek hd audio or nvidia audio (maybe both or i dont know) cuz when i update my gpu, the audio seems to update too, iv tried changing from 24 to 16 and back again to 24 bit sound, change the Hz and still nothing, deleting and instaling again the drivers, nada, zero....and thats my case...sorry if it a long story and took u time to read it but if someone out there has the same issue or something like it and managed it to fixed it then by all means pls share ur wisdome cuz i dont really want to go back to w7 (since i can still revert back to it) but if i have to and come back again (in a year) to w10 then thats what i shalt do...thats it.
Thx all for yer time...may the force be with us all and very very sorry for the bad bad writting/grammar, english is my second language but my writing skills have been going down down down down and btw, why dont this have spellcheck? xD .... i hope i find or am given a solution, farewell
