Noise from Digione board

[smith123]

Hello,

 

I've notice a noise from my Digione Player when standing close to it. Is this normal? It is like a high pitched noise (also appear when nothing is connected and without SD card) 

 

I tried changing the DBi board but the noise is still there.

 

It is the Digione 1.2 board. I noticed that the 1.1 board is more quitet.  

 

Thanks.

I'm having the exact same issues using my DigiOne Player (1.2 board). The noise is constant when using different power supplies -  LPSU and both Allo's and Raspberry's standard ones. Very annoying, as the main reason for using the DigiOne was to get rid of the noise...

Just took apart my DigiOne Player to get to the bottom of this. With only the Raspberry connected to the power there is absolute no sound. Adding the DigiOne HAT and the screeching is there.

 

@Allo Support any ideas?

And here it is in my open cupboard with the linear supply, where the noise gets even amplified and audible on the sofa when is silent in the room.
