Default DC to DC Step Up LM2577

I bought DC to DC LM2577 Module, V in 5v and V Out 18v. The module was operated as normal for the voltage but there is the high frequency leak to audio. I already filter with Capacitor but it does not help.

Anyone can suggest how to solve that problem, thank you in advance
