Reply To: [NEW UPDATE] Pulsating sound with new Hifiberry Amp2

Hello,

I tested with 2 power supply, Pi 2 and 3 and no external device.
I also test with another amp2.. with a plain raspian and piCore, always this noise after a while.
The noise appears after a while (sometime 6 hours…).
I joint 2 audio files with noise (when playing and not playing song) => How can I send you this files?

Thank you.

Christophe
