You Reply: Mine is z8350.
I installed windows 10 Home but I think professional will be same.
I lost all my problem.
Sound jack is ok.
and unstable usb 2.0 port is just related with power supplier. (you do not need install windows again only for this.)
I spend around 5 hours, because I had many trial errors.
So I wrote down everything to remember what I did, and this is information for myself if I have to install again.
I think, you can finish within 2 and half hours ( because you have to spend at least 1 hour for update windows 10 from Microsoft).
