Jaune has a semblance. It's mentioned in the DVD commentary by Monty Oum when Cardin punches him and the flash appears. Also, Semblance has a specific sound just like weapons and the sound you heard when the flash appears is another proof that it was indeed his semblance. Although Monty said that it wasn't his full semblance, it was just a glimpse of it, his true semblance is still unknown but he already showed that he has one so there you have an answer.
