Using sound in Windows

The following issues are specific to managing sound for Windows:

| In Windows, a sound that is already playing in either sound channel overrides the sound in a QuickTime or AVI video or a Flash movie. It also prevents the video sound from playing even after the sound in the sound channel has stopped. Once the sound in a digital video has started, however, it overrides a sound in either sound channel.
| To mix QuickTime audio tracks with internal Director sounds, use the `soundDevice` system property to specify QT3Mix or install the Microsoft DirectSound sound driver software version 5.0 or higher (available from www.microsoft.com), and use the `soundDevice` property to specify DirectSound.See `soundDevice` (Note that Windows NT4 does not support DirectSound 5.) Check the Director Support Center Web site for the latest developments related to this issue.
| The default number of sounds that Director can mix in Windows is eight. This number can be decreased by modifying the value for MixMaxChannels in the Director.ini file in the Director folder.
