Description

TerminateByPriority

32

If the hardware has no available voices, a currently playing buffer will be stopped to make room for the new buffer. The buffer prematurely terminated will be the one with the lowest priority as set by the [color=var(--blue)]priority parameter [color=var(--blue)]Play method for the buffer.

TerminateByDistance

16

If the hardware has no available voices, a currently playing buffer will be stopped to make room for the new buffer. The buffer prematurely terminated will be selected from buffers that have the buffer's [color=var(--blue)]BufferDescription.Mute3DAtMaximumDistance property set to true and are beyond their maximum distance. If there are no such buffers, the method fails.

TerminateByTime

8

If the hardware has no available voices, a currently playing nonlooping buffer will be stopped to make room for the new buffer. The buffer prematurely terminated is the one with the least time left to play.

LocateInSoftware

4

Play this voice in a software buffer only. This flag cannot be combined with LocateInHardware or any voice management flag.

LocateInHardware

2

Play this voice in a hardware buffer only. If the hardware has no available voices and no voice management flags are set, the [color=var(--blue)]Play method fails. This flag cannot be combined with LocateInSoftware.

Looping

1

After the end of the audio buffer is reached, play restarts at the beginning of the buffer. Play continues until explicitly stopped. This flag must be set when playing a primary buffer.

Default

0

Play this voice with the default settings.
