Maybe you could delete the delay() in the library to decrease the latency to have a quick responce if there is.
Thank you for helping xxLeff but that make no effect.
My pbm is that when the trigger high sounds be play directly and is not the case. The 10ms become after the play cmd. In fact, in addition to the delay the begin of sound is "eaten". I have to go to the evidence: this module is not make for this
