Configures a sound device for a sound input operation.

After you configure the sound device, you can use the SI Start VI and the SI Read VI to transfer data from device.

	device is the device you access for a sound operation. Use the default value of 0 if you have one audio input to the host computer, which is common. The value ranges from 0 to n–1, where n is the number of input or output devices on the computer.
	sound format specifies if the sound operation is mono or stereo, sets its playing rate (speed), and sets the sound as 8- or 16-bit sound. Note  Setting sound quality to stereo, rate to a high value, and bits per sample to 16 bits per sample increases memory usage when you record sound. Also, not all operating systems and sound cards support all sound format options. sound quality sets the sound operation as mono or stereo. rate sets the sample rate in hertz for the sound input operation or the update rate for the sound output operation. You can select 8000, 11025, 22050, or 44100. bits per sample sets the sound operation for 8 bits or 16 bits per sample.
	buffer size is the size in bytes of the internal buffer that LabVIEW uses to transfer data from a device. If you receive an overwrite error, increase the buffer size. The default value is 8192.
	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 PDA Error Handler VI 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 out returns an identification number associated with the configuration on the device you specify in device. You can wire task ID out to other sound input 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. 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.
