Static Address in Dynamically Loaded DLL

Question

I am trying to re-write the following function in my injected DLL.

mov edi,edi
push ebp
mov ebp,esp
mov eax, [sound.dll+1AE0]
push eax
mov ecx,[ebp+08]
mov eax,[ecx]
mov eax,[eax+0C]
push eax
call sound.dll+7C640
pop ebp
ret 0004

I am loading my DLL via CreateRemoteThread. Is there a way to get the address of sound.dll+1AE0 (or linkage) when the DLL is loaded without having to to do GetModuleHandleEx and calculate the address dynamically?

Maybe with some imports or some linkage artifact?

Thanks!

EDIT:

The GetModuleHandleEx approach will look like:

DWORD mem1AE0=0;

Load mem1AE0 with sound.dll+1AE0 address

and then in my function:

_declspec(naked) void MyFunction() { 
    __asm { 
        mov edi,edi 
        push ebp 
        mov ebp,esp 
        mov eax, mem1AE0 
        mov eax, [eax] 
        push eax 
        mov ecx,[ebp+08] 
        mov eax,[ecx] 
        mov eax,[eax+0C] 
        push eax 
        call sound.dll+7C640 
        pop ebp 
        ret 0004 
    } 
} 

The problem is when I have a call [sound.dll+XXXX] instruction

In that case I need to create a variable which will point to that memory

DWORD memXXXX=0;

Load it with the correct address and also create a proxycall DWORD

DWORD memXXXX_content=0;

and then do:

push eax 
mov eax, memXXXX 
mov eax, [eax] 
mov memXXXX_content, eax 
pop eax 
call memXXXX_content 

which is totally inefficient unless I am doing somehting wrong?

Thanks

EDIT: I believe there is no way to get static links if you are dynamically loading your DLL.
