Sets the volume at which the sound output device plays.

(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.

Note Some Linux distributions use a version of the OSS sound driver that does not support setting volume through the DSP device file. LabVIEW cannot set the output volume on these distributions and returns a warning.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • iu32.png task ID out —

    task ID out is the manipulated sound operation originally passed to the task ID parameter.

  • ierrcodeclst.png error out —
