Trying to add - on but every time I add from zip file, then trying to add from repository kodi turns off. Why is this happening
Kodi always stops, a few seconds behind with audio and picture, how do I fix

What are you trying to install, and from which site?
For the sync issue, in the on-screen display you can adjust the delay time between audio and video to resynch things, or there are settings in the main settings menus to set synchronisation options.
