Hi, finally I did attempt to use the regular plug psu to feed the GPIOs.
Now, I have a Hifiberry DAC+ on top of them, so I released it, pluged on the wires and re-installed the DAC ontop.
First, power was on but Rune was not loading. Rebooted, this time Rune came up. I then started a play, but after a few seconds the playback stopped.
I removed this for now, but is it related to having the DAC on the GPIOs ?
