System Requirements

This utility works on Windows Vista, Windows 7, Windows 8, Windows 2008, and Windows 10. Both 32-bit and 64-bit systems are supported.
Windows XP and older systems are not supported.

The /Stdout command-line option

By default, when you use a command to get the current sound volume or mute state, the value is returned through the return code of the .exe file and you can get it with the %errorlevel% variable, for example:
svcl.exe /GetPercent "Realtek High Definition Audio\Device\Speakers\Render"
echo %errorlevel%

With svcl.exe, there is another option, you can add the /Stdout command, and then the value will be send to stdout and it'll be displayed inside your command prompt window, for example:
svcl.exe /Stdout /GetPercent "Realtek High Definition Audio\Device\Speakers\Render"

If you add the /Stdout command to a set command ( /SetVolume, /SetDefault , /Mute , /ChangeVolume , and others....) , the list of the found sound items will be sent to Stdout, so you can see which sound items are affected by the executed command.
