@Heiner: How do you test? With max2play 2.44, LM serveur and squeezelite?
If you cut off the player via LMS the noise stop. When you cut off you hear the plusating noise just once..
Turn on again and the noise come back (after a few time). I won’t cut off rhe play at each time!
I switch my two defect Amp2 with two Amp+ and this noise never come.
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?
