Last Modified: January 12, 2018

Opens a file and starts playing it immediately.

connector_pane_image
datatype_icon

device ID

The input or output device you access for a sound operation. The value ranges from 0 to n-1, where n is the number of input or output devices on the computer.

Default: 0

datatype_icon

path

The absolute path to the file from which you want to play sound data.

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

timeout

Time, in seconds, that the node waits for the sound operation to complete. This node returns an error if the time elapses, unless timeout is set to 0. If you set timeout to -1, the node waits indefinitely.

Default: 0

datatype_icon

task ID

Reference to the configured sound device. You can pass task ID to other sound operation nodes.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
