CPlayerEngine::CPlayerEngine()

iMdaAudioPlayerUtility = CMdaAudioPlayerUtility::NewL(*this);
iCurrentVolume = 5;
}

void CPlayerEngine::PlayL(const TDesC& aFileName)
{
if ( aFileName != KNullDesC )
{
iBufFileName.Zero();
iBufFileName.Copy(aFileName);
TParse parse;
parse.Set(aFileName, NULL, NULL);
StopL();

iMdaAudioPlayerUtility->OpenFileL(aFileName);
}
}

void CPlayerEngine::PlayL()
{
if ( (iState == EReadyToPlay) || (iState == EPause) || (iState == EDailling))
{
iMdaAudioPlayerUtility->SetVolumeRamp(TTimeIntervalMicroSeconds(1500000));
iMdaAudioPlayerUtility->Play();
iState = EPlaying;
}
}

void CPlayerEngine::StopL()
{
if(iMdaAudioPlayerUtility && iState == EPlaying)
{
iMdaAudioPlayerUtility->Stop();
iMdaAudioPlayerUtility->Close();

iState = EReadyToPlay;
}
}

void CPlayerEngine::MapcInitComplete( TInt aError,
const TTimeIntervalMicroSeconds& aDuration )

if ( aError )
InitCompleteFailed(aError);
else
InitCompleteSucceed();
}

void CPlayerEngine::InitCompleteSucceed()
