The most effective way to play the snap sound is to use the CAknKeySoundSystem class. The following code example explains how to implement the feature in your own application:

myapp.h

#include <aknsoundsystem.h>
 
const TInt KSnapSoundId = 2;
 
class MyClass
{
...
 
private:
 
CAknKeySoundSystem* iCameraSound;
 
};

myapp.cpp

void MyClass::ConstructL()
 
{
 
...
 
iCameraSound =
 
static_cast<CAknAppUi*>(CEikonEnv::Static()->AppUi())->KeySounds();
 
if (iCameraSound)
 
{
 
TRAPD(error, iCameraSound->AddAppSoundInfoListL(
 
R_CAMERA_SNAP_SOUND));
 
if ((error != KErrAlreadyExists) && (error != KErrNone))
 
{
 
User::LeaveIfError(error);
 
}
 
}
 
}
 
void MyClass::PlaySnapSound()
 
{
 
iCameraSound->PlaySound(KSnapSoundId);
 
}

Also add the following code into your application's resource .rss

#define KcameraSoundFile
 
"Z:\\system\\sounds\\digital\\Camera1a_2_8kHz.wav"
 
#define KSnapSoundId 2
 
RESOURCE AVKON_SOUND_INFO_LIST r_camera_snap_sound
 
{
 
list =
 
{
 
AVKON_SOUND_INFO
 
{
 
sid = KSnapSoundId;
 
priority = 45;
 
preference = EAknAudioPrefCamera; // defined in avkon.hrh
 
file = KCameraSoundFile;
 
}
 
};
 
}
