SoundVolume - set or get the system speaker sound volume

SoundVolume sets or gets the computer's system speaker sound volume

Syntax:
volume = SoundVolume(volume);

SoundVolume(volume) sets the system speaker sound volume. The volume value should be numeric, between 0.0 (=muted) and 1.0 (=max).

volume = SoundVolume gets the current speaker sound volume (0.0-1.0).

volume = SoundVolume(volume) sets the system speaker sound volume and returns the previous volume value (from before setting the new value).

Note:
SoundVolume relies on Java functionality that is fully supported and documented. In this respect, SoundVolume is different from some of my other Matlab-Java utilities that rely on undocumented code.
