Hi. Sry fo my english.
I have laptop with Win 8.1 x64 and voxcommando2/
And I need help. )
Task is to adjust system sounds via voxcommand.
how can I do it?
Sorry for noob question...

Hi Esgal,

There is a bug in the audio in version 2.1.4.8 so if you are using that version I strongly recommend that you upgrade to version 2.2.0.7
http://voxcommando.com/home/downloads/

The added bonus is that 2.2.0.7 offers the option to switch to a Russian UI !

If for some reason you do not want to upgrade you can replace the dll file with the attached file.  Look in your VoxCommando folder and then in the subfolder named "dlls".

You must close VoxCommando before trying to replace the dll. 
After replacing the file check to see if you need to unblock the dll.

As James says, the bug in version 2.1.4.8 affects the system sound actions.

Here are some examples of how to adjust the system sound, generally.

This is a command group. You can copy and paste all the code into your command tree to test and edit the commands.
