There is no documented origin for PollyBuzz No Sound, and the name looks like a user-generated label rather than a known character, game or show. Silent clips like this circulate on soundboards as joke uploads, where the blank audio itself becomes the punchline. With only a couple seconds of runtime, it is shared as a troll button, a placeholder for missing audio, or a comic beat in meme edits. Its continued use comes from that simple subversion of expecting sound and hearing nothing.
