No audio no video music playback

[Femin]

So i installed sierra today on my pc having kaby lake i7 7700 and gigabyte z270m-d3h
with working ASUS ROG STRIX gtx 1080
now i installed sierra and in audio drivers i selected VoodooHDA and ALC for 100/200 Series (also tried ALC for ASUS ROG STRIX ONLY)
but on reboot what happens is,
when i open youtube, it loads the video, thumbnail is also in HD
but it wont play only... the button will change to play and pause but the video wont play, so i downloaded a .mp3
opened it in itunes.. same thing happens with it.. it wont play!!
what am i missing or doing wrong ?

i dont mind doing a fresh install.. but what did i do wrong ? so while doing a fresh i can take care of it

selected VoodooHDA and ALC for 100/200 Series

100/200 Series patch is for AppleHDA.kext only; that is why the selection is not included as a Voodoo selection.
If you installed Voodoo, you have a Voodoo problem.

so now what should i do for audio ?
i downloaded voodooHDA from different locations like insanelymac and many more like sourgeforge but none of them is giving me audio

[EDIT]
Now i installed ALC1220A and 100/200 series patch
now i am getting audio but its toooo low and it garbles too,
what is the fix for this ? i removed VoodooHDA kext from /Library/Extensions

Only VoodooHDA does not give me any output options

alc1220 and alc1220A work but i get very low sound, any fix for that ?

alc1220 and alc1220A work

Different codecs, only one should work; installation problem.
