About SndDrv.dll

I Rename my D3D Dll hack to: SndDrv and Give a Error saying "Error With Sound, the game will Close" an error like this..
How i can make a hack whit no erros?
All Hacks haves a Second SndDrv2.dll , say to me pliss, what its this

well, my hack i renamed it it from "SndDrv.dll" to "SndDrv2.dll" while having the original SndDrv.dll it is usually 76.0 kbs so u dont get confused with other ones... and renaming it really worked for me, and also i had sounds on

Hmm to make that's working with memory it's easy

But i think it's very hard to make that's working in D3D

u didnt see my tut?
