Click sound on Beocreate pcb

Hi,

 

I noticed a strange click sound on the pcb of the Beocreate v1.0.2

My setup is:

Beocreate

Raspberry Pi 3B+ 1GB v1.3

Software Moode Audio Player 6.5.2

Button with 4k2 resistor on GPIO16 to GND

 

Behaviour:

When I skip to next track or when I press play (either with GPIO or in Moode) I hear a click on the PCB (also a very small pop sound from the Loudspeaker, but that does not bother me) 

When I change the volume to "0" there is no click sound on the pcb when I skip to the next track (GPIO or Moode)

 

I tried the same on my hifi system. There I have a Raspberry Pi 4 with Moode connected to a USB Dac. There is no click sound on the pcb when I skip to the next track (GPIO or Moode). So maybe its not coming from the Raspberry Pi?

Should I be concerned about this? Can anybody tell me from which part on the pcb this sound is coming from?

 

Apart from this I am having a lot (!) of fun with the Beocreate :)

 

Cheers

Matthias
