Нет способа воспроизвести любой звук с узла exec из node-red, хотя через командную строку raspberry pi он работает с той же командой:
aplay -D default /home/pi/.node-red/public/Cuckoo-sound-effect.wav
Даже вывод узла красный:
Воспроизведение WAVE '/home/pi/.node-red/public/Cuckoo-sound-effect.wav': 16-битный Little Endian, частота 44100 Гц, стерео
Это реализованный поток:

Может кто-нибудь указать, что я делаю не так? Большое спасибо !!
