Speaker Configuration

DirectSound uses the speaker configuration—that is, the position of the speakers relative to the listener—to optimize 3-D effects for the user's sound system.

In Windows 98 and Windows 2000, the speaker configuration can be set by the user in Control Panel. An application can retrieve this value by using DirectSound8.GetSpeakerConfig and override it by calling DirectSound8.SetSpeakerConfig.

There is no guarantee that SetSpeakerConfig will have an immediate effect; it might simply change a registry setting that will not take effect until the computer is restarted. Instead of using this method, applications should advise the user to change the speaker configuration through Control Panel.
