SoundVolume - set or get the system speaker sound volume

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

Description

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.

I used this to integrate it with a GUI slider to control the system volume. Worked great! Had to slightly modify te code..
ctrls(ctrlIdx).getType to ctrls(ctrlIdx).getType.toString..with Yair Altman's help to get it to work on my system. Windows XP with MATLAB 7.0.4.365(R14) SP2, but otherwise works fine!
