Configures a sound output device to generate data. Use the Sound Output Write VI to write the data to the device.

(Windows) You must have DirectX 8.0 or later to use this VI. (Linux) You must have the Open Sound System (OSS) driver to use this VI.

Examples

	number of samples/ch specifies the number of samples per channel in the buffer. Use a large number of samples for continuous operations. Use a smaller number of samples if you want to use less memory.
	sample mode specifies whether you intend to write just once (Finite Samples) or continuously (Continuous Samples). In Finite Samples mode, call Sound Output Write only until you have written the number of samples specified in number of samples/ch. In Continuous Samples mode, you can call Sound Output Write repeatedly as needed.
	device ID is the input or output device you access for a sound operation. In general, most users should select the default value of 0. The value ranges from 0 to n–1, where n is the number of input or output devices on the computer.
	sound format sets the playing rate, the number of channels, and the bits per sample of the sound operation. The values for each of these controls is dependent on your sound card. Note  Setting sample rate (S/s) and bits per sample high uses more of the computer memory when the VI runs. Also, not all operating systems and sound cards support all sound format options. sample rate (S/s) sets the sampling rate for the sound operation. Common rates are 44,100 S/s, 22,050 S/s, and 11,025 S/s. The default is 22050 S/s. number of channels specifies the number of channels. This input can accept as many channels as the sound card supports. For most sound cards 1 is Mono and 2 is Stereo. bits per sample specifies the quality of each sample in bits. Common resolutions are 16 bits and 8 bits. The default is 16 bits.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	task ID returns an identification number associated with the configuration on the specified device. You can pass task ID to other sound operation VIs.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
