Following on from how to get Node-RED to run as a service on a Pi I'm having trouble playing a sound via exec node
So I'm trying to play a wav file out thru the Pi audio jack
It works fine when I run Node-RED directly from a terminal
As I was typing this I suddenly thought that the sound is probably defaulting to going out thru HDMI and with a bit of googling and experimenting I came up with this as my solution
which tells it to explicitly use the audio jack and all good 🙂 😃

You could also define the headphone jack as the default in your asound.conf file.
Although that can be a little bit confusing too 🙈
