Do a slow double R press (as shown in the video below) when you first spawn in the pyramid, and only press C-Down after you've left the lowering platform. Spam C-Left after the star spawns during the dive rollout and longjump into the star.
The sound glitch on SSL secrets will only happen on the Japanese version, so if you run 70 star on English (which is optimal) you don't have to worry about this.
