There could be a number of reasons. Firstly, fanfiction is often a product of the imagination of fans and not part of the official magical realm that Harry inhabits. Secondly, it doesn't have a natural form of being audible. For example, if we consider the magic in the Harry Potter world, there's no spell or charm that would make fanfiction audible to him. Also, the nature of fanfiction is that it's created outside the official narrative, so there's no built - in mechanism for Harry to be able to hear it.
Maybe it's because fanfiction exists in a written or digital form and doesn't have an audible component by default. Harry, like any normal person, can't just magically hear the words of fanfiction unless it's been read out loud to him or turned into an audiobook.
Maybe Ben is deaf. So, regardless of what the fanfic is, he can't hear it in the traditional sense of auditory perception.
It could be that the source of the story has some technical glitch, or there's interference in the audio transmission. Have you tried using a different device or checking the connection?
