Using Mute with ltmfCapture Example for C++

void SetCaptureVolumeMuteBalance(IltmfCapture *pCapture) 
{ 
   VARIANT_BOOL vrtMute; 
   long lVol, lBalance; 
   // unmute it if currently muted 
   pCapture->get_Mute(&vrtMute); 
   if (vrtMute == VARIANT_TRUE) 
      pCapture->put_Mute(VARIANT_FALSE); 
   // adjust the volume 
   pCapture->get_Volume(&lVol); 
   if (lVol == 0) 
      pCapture->put_Volume(-10000); 
   // adjust the balance 
   pCapture->get_Balance(&lBalance); 
   if (lBalance != 0) 
      pCapture->put_Balance(0);
