Xavier,

The preenFM2 PCB has been shipped and is on the way to you

Xavier, if you ever work out what happened after having a look for yourself, please post here! I've been following this thread the whole time and I really want to know what was up.

I found it.   
It was a shortcut between 2 solder points.

The blue one (see pics for color) responsible for sending the sample to the DAC and the close junction responsible for lightning the LEDs.
That must have distored the SPI signal which became ununderstable for the DACs.

I removed the tiny wire with my soldering and the sound came...
I'll send your PCB back. You can keep the extra one i sent you 

[horridus]

Xavier, wow, that is really great! I'll send the board and parts back to you as well :>)

[SirPrimalform]

Wow, that is a tiny bridge!

[horridus]

Looks just like one of my grey beard hairs
