You could always play the sound synchronically in a thread instead. I haven't 
tested the code I've written, but you'll get the picture I think.

Kind regards,

#include <mmsystem.h>
#include <list>

using namespace std;

class WavePtrList : public list<char *> {
     // extend the WavePtrList class here if you need it
};

class PlaySoundThread : public TThread {
private:
     WavePtrList Waves;
public:
     __fastcall PlaySoundThread() : TThread(true) {
         // do any initialization here
     }
     __fastcall ~PlaySoundThread() {
         Terminate();
         PlaySound(NULL,NULL,SND_PURGE|SND_SYNC);
         WaitFor();
     }
     void AddWave( char *Wave ) {
         Waves.push_back(Wave);
         if( Suspended ) Resume();
     }
     void RemoveWave( char *Wave ) {
         Suspend();
         Waves.remove(Wave);
         if( Waves.size()!=0 ) Resume();
     }
     void __fastcall Execute() {
         WavePtrList::iterator wav=Waves.begin();
         while(!Terminated) {
             PlaySound( *wav, NULL, SND_SYNC | SND_NOSTOP | SND_MEMORY );
             if( ++wav == Waves.end() ) wav = Waves.begin();
         }
     }
};
