Audio 在Symbian S60中播放声音

我是Symbian的新手，在播放声音时遇到了麻烦。我看了很多例子，但我找不到我的错误。还有其他人有过这样的经历吗？任何方向都会有帮助。我用另一节课的计时器打开游戏

标题：

class TonePlayer : public CBase, public MMdaAudioPlayerCallback
{
public:
    static TonePlayer* NewL();
    static TonePlayer* NewLC();
    ~TonePlayer();

    void Play();
    void Stop();

protected:
    TonePlayer();

    void MapcInitComplete(TInt aError, const TTimeIntervalMicroSeconds &aDuration);
    void MapcPlayComplete(TInt aError);

private:
    CMdaAudioPlayerUtility* m_pAudioPlayer;

    void ConstructL();
};

cpp：

诺基亚论坛的人帮了我的忙，这里是最终的结果

TonePlayer* TonePlayer::NewL()
{
    TonePlayer* self = NewLC();
    CleanupStack::Pop(self); 
    return self;
}

TonePlayer* TonePlayer::NewLC()
{
    TonePlayer* self = new (ELeave) TonePlayer();
    CleanupStack::PushL(self);
    self->ConstructL();
    return self;
}

TonePlayer::TonePlayer()
{
}

TonePlayer::~TonePlayer()
{
    delete m_pAudioPlayer;
    m_pAudioPlayer = NULL;
}

void TonePlayer::ConstructL()
{
    MProEngEngine* pProfileEngine = ProEngFactory::NewEngineLC();
    MProEngProfile* pProfile = pProfileEngine->ActiveProfileLC();
    MProEngTones& oTones = pProfile->ProfileTones();

    m_pAudioPlayer = CMdaAudioPlayerUtility::NewFilePlayerL(oTones.MessageAlertTone(), *this);

    CleanupStack::PopAndDestroy(2);
}

void TonePlayer::MapcInitComplete(TInt aError, const TTimeIntervalMicroSeconds &aDuration)
{
    if( aError == KErrNone  )
    {
        m_pAudioPlayer->SetVolume(m_pAudioPlayer->MaxVolume());
    }
}

void TonePlayer::MapcPlayComplete(TInt aError)
{
}

void TonePlayer::Play()
{   

    m_pAudioPlayer->Play();
}

void TonePlayer::Stop()
{
    m_pAudioPlayer->Stop();
}
