All I can conclude is that you guys are fucking up your systems and Windows very badly
To get all confusions aside I have two systems :
Self made MEDIA PC based on Asus-Z170A with ALC892 DTS / DTSI out of the BOX no modifying needed
Gaming PC hp OMEN Desktop X 900-000nx with ALC1150 with DTS HeadphoneX and DTS Studio Sound out of the BOX and modified drivers NEEDED to be able to ENABLE DTS- Interactive however the method enables Dolby Digital Live as well a PLUS for me but unnecessary in my case.

So here we are me with TWO systems working absolutely fine and you with your systems with all kind of BS going on regarding DDL and DTS-I ..how ???? enlight me please ?
