How can I unmute the sound in Windows using Matlab?
In VBA this can be done using elegantly:
Dim WshShell
Set WshShell = CreateObject("WScript.Shell")
WshShell.SendKeys (Chr(&HAD))
But in Matlab I faild to use the method SendKeys to the method:
f=actxserver('WScript.Shell')
The post of Yair Altman: http://www.mathworks.com/matlabcentral/fileexchange/25584-soundvolume-set-or-get-the-system-speaker-sound-volume does unfortunately not work either. Any help on this?

What version of Windows are you using? How many and what types (i.e., internal, USB, firewire) of soundcards are you using?

Win XP and Win7. I'm interested in the solution for both environments. It's just an internal soundcard. Again - in VBA the SendKeys method works well - but I fail to correctly call it in Matlab.

Youe posted code doesn't work for me in VBA (Excel 2010, Win 7). And it also doesnt work in VBS. Are you sure that this code works on Win 7 and XP the same way?

"Does not work" is not sufficient description of the problem with Yair's Java tool.
