You may have some audio when opening WinToolkit using the latest test builds. This is because I was experimenting with a hidden advert within WinToolkit and didn't realize they may have audio. Don't worry it's not a virus or anything like that. I will figure out how to turn off the audio for the next build. You won't see the advert in any shape or form but it will allow me to gain extra clicks. If I can't remove the audio, I will just remove it entirely.
