I'm looking for ideas guys.

I have a program called MPG123 - and that plays MP3 files. If I go to a command prompt as Pi - and run mpg123 /home/pi/pete.mp3 it works.

On my raspberry Pi - if I use the NODE-RED exec node to do the same thing - it works. ALL IS WELL.

I've a new machine - a NANOPC2... I made a user Pi - it has the same permissions as the Raspberrry Pi -I ran the same installation script for everything - node-red etc etc.... and the mp3 program - exactly as I would on a P1

At the command line as user Pi, the mpg123 /home/pi/pete.mp3 works a treat - just like the PI

But in node-red - I cannot get a thing out of the EXEC node - it looks the same, the code is the same - but nothing comes out - no error messages in DEBUG.

Utterly lost... any ideas?

Pete.

Forget it guys - I rebooted AFTER giving PI all the permissions - works a treat.
