many thanks Bruno, I'll give the code a go.

ok i think i've figured out my issue, it would seem my WT5001M02-28P repeats the sound file as default which it shouldnt accordning to the PDF file. To fix the issue I just added this code to the beginning just after you define the serial settings. Serial.write(0x7E); Serial.write(0x03); Serial.write(0xA9); Serial.write(0x00); // added this code for single and no cycle play Serial.write(0x7E);

I have the exact same problem, I've tested the switches as suggested by Sergeant but its not that, if I press the fire or reload switch then the relevant sound keeps looping until I press something else... then that sound loops

how difficult (and is it possible) to make this into a 2 button only option? For example button 1 for trigger, then say button 2 for reload and button 2 held down for a couple seconds for weapon select.
