The anonymous reader is wrong. A supernova would be accompanied by a large amount of shockwaves through the star, and a large amount of pressure waves. There would be no sound, in the sense that there would be no neurological interpretations of these phenomena, but they would still happen.
It's likely that sound can be detected in space with the use of laser microphones. The sound won't be conducted through space, but that doesn't mean the ejecta isn't quivering, or that the quivering can't be neurologically assimilated.
