Uninstalling Virtual DJ drivers/device

I try to uninstall VirtualDJ software from a macbook pro ruing El Capitan, following instructions delivered by both official site and users forums ->

• delete app in application folder
• delete preferences file : Users/me/Library/Preferences/com.atomixproductions.virtualdj.plist
• delete kext file : Users/me/Library/Extensions/com.atomixproductions.virtualdj.kext
• delete virtualdj folder located in documents folder and in Users/me/Library/

All of that seems very easy to do, but I still have "VirtualDJ Advanced Audio" device that still appears in my list of output devices :/

I have searched over all my system folders for a kext extension to manually remove, but nothing founded :(

Is there any way to locate it ?
