Play an [AudioStream] at a given offset, volume, pitch scale, playback type, and bus. Playback starts immediately.
The return value is a unique integer ID that is associated to this playback stream and which can be used to control it.
This ID becomes invalid when the stream ends (if it does not loop), when the [AudioStreamPlaybackPolyphonic] is stopped, or when [method stop_stream] is called.
This function returns [constant INVALID_ID] if the amount of streams currently playing equals [member AudioStreamPolyphonic.polyphony]. If you need a higher amount of maximum polyphony, raise this value.

Specifies the preferred output latency in milliseconds for audio. Lower values will result in lower audio latency at the cost of increased CPU usage. Low values may result in audible crackling on slower hardware.
Audio output latency may be constrained by the host operating system and audio hardware drivers. If the host can not provide the specified audio output latency then Godot will attempt to use the nearest latency allowed by the host. As such you should always use [method AudioServer.get_output_latency] to determine the actual audio output latency.
Audio output latency can be overridden using the [code]--audio-output-latency &lt;ms&gt;[/code] command line argument.
[b]Note:[/b] This setting is ignored on Android, and on all versions of Windows prior to Windows 10.

A value of [code]1.0[/code] completely mutes one of the channels if the sound is located exactly to the left (or right) of the listener.
The default value of [code]0.5[/code] is tuned for headphones. When using speakers, you may find lower values to sound better as speakers have a lower stereo separation compared to headphones.
