These hooks can be used to add callbacks that would be run before and after the main playback hooks. These hooks would be called for all amps, before moving on to the next hook, i.e. pre_playback_hook would be called for all amps, before the playback_hook is called for all amps, then finally the post_playback_hook is called for all amps.
