sound interruption 24bits 96khz - hifiberry digi

Hi all,

I am facing some sound interuptions when playing 24bits 96khz flac file with my raspberry pi 3 + hifiberry digi.

Have you noticed the same ? Everything is fine with standard 44khz/16 bits files.

Many thanks,


I found the solution by myself.

It is due to a grounding problem. The hifiberry digi has an output transformer at SPDIF output to provide galvanic isolation.
But at the other side, my dac is not grounded. Therefore it produces a floating ground particularly good to receive all kinds of interferences!

I put a cable to put ground on external conductor of SPDIF cable. Clipping dissappears!
Hope it can help somebody.


Clever investigation on your side, kudos!
