Fail to play infinite sound when loading the AudioEngine by ThreadPool

    Fail to play infinite sound when loading the AudioEngine by ThreadPool

    Reply Quote

    Vista, VS2008, C#.

    When I load audio files by following code with a Thread pool,  I found the sound with infinite setting cannot play,  but the sounds without infinite setting are played well.

    public static void Initialize()
    {
            ThreadPool.QueueUserWorkItem(new WaitCallback(LoadAudioFiles));
    }
    private     static void LoadAudioFiles(Object stateInfo)
    {
        audioEngine =     new AudioEngine(audioEngineFileName);
        waveBank = new WaveBank    (audioEngine, waveBankFileName);
        soundBank =     new SoundBank    (audioEngine, soundBankFileName);
    }

    Any one have any suggestions?  Thanks.

    Don't use a separate thread. What do you think you're gaining by doing it that way?

    When loading those audio files,  it looks take 3~4 seconds,  I'm going to play the sounds in UI thread, but if I load the audio files in UI thread. It will freeze UI in loading time. I mean I play it when the thread loading finished. Why the infinite sound cannot be played well?  Is it a known issue?   Thanks.

    So you load the sounds before starting your UI. If you think this is a bug, report it on the Connect site.

    Thanks, Jim.
    Finally I think I figure out the where the problem is.  I found that if I set the playlist type of cue to interactive. I will fail to play it after loading the library by another thread. It is not related with the infinite/finite setting.  I think I don't need the interactive feature, so I just change it to others(Eg. Ordered).  It works now.
