Disable autoplay audio files (mp3 in this case, but any and all)

[Leo]

This method should work, assuming the Windows Media Player preview handler is working. Check that you can view the files in File Explorer's viewer pane to test that.

Prevent Autoplay of Media Files in Preview Pane

In Opus12, movie and sound files are automatically played in preview pane. I would like them to be played only when I press start button. I think that their was an option for that in some older versions. Can you help?
