## Arguments

- *server*

  Specifies the connection to the audio server.

- *destination*

  Specifies the device to output the audio data.

- *volume*

  Specifies the volume.

- *mode*

  Specifies the line mode for the output device. Currently the following line modes are defined: **AuDeviceOutputModeNone**, **AuDeviceOutputModeSpeaker**, **AuDeviceOutputModeHeadphone**, **AuDeviceOutputModeLineOut**.

- *sound\_data*

  Specifies the sound information.

- *flow*

  If non-NULL, returns the flow ID.

- *volume\_mult\_elem*

  If non-NULL, returns the index of the volume multipler element.

- *monitor\_element*

  If non-NULL, include an ExportMonitor element in the flow and return it's index.

- *status*

  If non-NULL, flush the output buffer and return the status from the server.

## Description

**AuSoundPlay** creates a flow to play audio from any source on *device* and returns a pointer to the event handler created or NULL if there was an error. The *sound\_data* structure contains the necessary information about the audio format and the data handling function.

## Errors

**AuBadDevice**.
