I hear a constant beeping (high frequency sound, not modulated by wifi activity) when the HIFI-Amp is connected. This does not occur with the x400 connected using the same pi and same power supply. Do you have any recommendations how to get rid of that annoying sound?

The 19v power supply is to weak for the rapsberry pi3. Is it possible to use a 19v powersupply for laptop with 4.65 A ?

So really no GPIO can be used for other purposes, for example an on/off button?

Please can you explain: what are the 3 holes for contacts in the right top corner of PCB? Seems to be for rotary volume control, that would be fine. In software you can accidentally increase the power and (accidentally) missing access to volume control over application, so the best would be physical control... Thanks

Hello friend, When install the AMP board on the Raspberry Pi, it will take the full GPIO PIN of your raspberry pi board. Hope to get your understanding! Best regards,
