Not a hard task...
In fact I wrote an article about resource files linked to an executable or inside a resource dll on http://bcbjournal.com.
So... Create a text file in notepad.
First line:
THEWAVFILE     WAV   TheWaveFile.wav

Save the file with extension .rc
Copy Brcc32.exe from bin directory to the directory of the rc file and of course the wav file....
Both files has to be present (rc and wav) or the content of the text file as file names.

Open a command prompt on that directory to use brcc to create a .res file as follows:
brcc32 -32 TheFileName.rc TheFileName.res
A .res file will be created with a size a bit greater than all the files included inside.
Add the res file to the executable using Project|Add To Project
The next time you will compile and link the wav file or whatever else will be included in the executable.

The hard part is to play the sound...
Usually I'm using DirectSound for that so all I ever needed is a buffer...
ANYWAY:
You can load the sound to a TMemoryStream as follows:
TMemoryStream   *Stream;
       HRSRC   ResHandle;
        HGLOBAL MemHandle;
        void *ResPtr;
        int   ResSize;
        char  *lpName;

        ResHandle = FindResource(HInstance, "THEWAVFILE", "WAV);
        MemHandle = LoadResource(HInstance, ResHandle);

Using the TMemoryStream->SaveToFile function you can save to a temporary file before use the playsound function if there isn't any other way.

        ResPtr = LockResource(MemHandle);
        ResSize = SizeofResource(HInstance, ResHan-dle);
        Stream = new TMemoryStream;
        Stream->SetSize(ResSize);
        Stream->Seek(0,0);
        Stream->Write(ResPtr, ResSize);
        Stream->Seek(0,0);

PlaySound works fine you just have to tell it the 'file' is a resource as follows:  

PlaySound("THEWAVEFILE",NULL, SND_RESOURCE);

or

sndPlaySound("THEWAVEFILE", SND_RESOURCE);

You do need to include the mmsystem.h header file.

I believe rc file needs to use WAVE not just WAV.  Depending on the file path/name you might have to use "" around the file name as well,  for example if the name has any spaces you need the quotes.

So first line:
THEWAVFILE WAVE TheWaveFile.wav

You can actually just add the .rc file to the project and the CBuilder will take care of building the .res file automatically.  Either way it gets the job done.

>>THEWAVFILE WAVE TheWaveFile.wav
Whatever can be used as long as the middle description in this line and the last variable on FindResource() is the same...
I tried that and verify it...:-)
Sometimes one needs to confuse others, like a kind of cryptography....

When doing the PlaySound/sndPlaySound methods to directly play the audio  from the resource only 'WAVE' works (using the SND_RESOURCE flag).  I would guess those MS SDK calls have hardcoded thier resource lookups.

If you load it into memory manually you are right,  anything will do as long as you  match the call to what you put in the resource file.

YES!
What I mean is to insert to and extract from resource...
I'm using that long time now, have all wav files inside a dll but I'm using DirectSound to play them...
DirectSound plays the sounds from a buffer (DirectSoundBuffer)...
