TOPIC

    When using QuickTime 3 on a Windows 95 or Windows NT computer you may experience audio breaking up. This article provides known solutions.


DISCUSSION

    The default QuickTime sound settings work for most computers. However, if you experience sound drop-out problems on your computer, here are some things you can try.

    If DirectSound is available for your computer, make sure you have the latest sound driver and the current version of Direct X.

    If you still experience sound problems, adjust the size of the sound buffer QuickTime uses. Larger buffers reduce the chance of drop-outs, but increase latency for interactive uses of sound.

    Adjusting the size of the Sound Buffers


      1. Open the Control Panels window.
      2. Open QuickTime Settings.
      3. Select the Sound Out panel.
      4. Select the WaveOut or DirectSound device
      Depends on your computer configuration.
      5. Click on the Options button at the bottom of the control panel.
      6. Adjust the settings
      7. Test the movie you were experiencing problems with.
      8. Keep adjusting the settings until the audio problem is corrected.

    DirectSound Settings

    The size of the sound buffer is set in milliseconds. Increase the buffer size until the drop-out is corrected.


    WaveOut Settings

    There are two numbers to adjust, the number of buffers and the size of each buffer in milliseconds. Adjust the number of buffers until any drop-outs are corrected. If you hear a stuttering, increase the individual buffer size until the stuttering is corrected.
