I want to control the volume of my Windows system from a JScript or VBScript script. Any ideas?

Also, can I unmute the system volume if it is muted?

The best way I can see for manipulating the system volume level on Windows without the need for installing additional software is to use VBScript in one of the following ways:

Toggle muted: (already mentioned in a previous answer)

Set WshShell = CreateObject("WScript.Shell")
WshShell.SendKeys(chr(&hAD))

Increase volume level:

Set WshShell = CreateObject("WScript.Shell")
WshShell.SendKeys(chr(&hAF))

Decrease volume level:

Set WshShell = CreateObject("WScript.Shell")
WshShell.SendKeys(chr(&hAE))

This should work for most modern Windows machines. I've tested this on Windows 7 and 8.1 and it works fine even when run with "do as" in LC, so it is possible to embed these scripts within an executable and run them without the need of saving them as individual files.
