click-clack / plop sound before playing a song


I have bough the bundle Kali + ALLO Piano:

This sits on a Raspberry Pi 3 and I am using the volume system build 2.224

The problem is that regardless from where I play songs (local, NAS, Spotify) I have always a noticeable sound before the music starts. It is a shot peak like a plop , clack. It is like a sound which is coming due to a power on signal, like it was was on old hifi components which did not turn off the speakers during power on cycle.

This is especial uncool if I hear music very loud, the bass speaker is showing the effect too :wink:

I am wondering if I could change this behavior (timing)?

Thanks in advance

It looks that I am the only one how experiences this issue, is this right?
