Hi everyone !
I was very exited to try my new sound system, but when I plugged the power cord in the hifiberry it burned instantly.
I plugged only a 12v - 4.2a in the HifiBerry (no alimentation in the Rpi, only hdmi and ethernet, speaker unplugged has well). Then the chip instantly burned.
See attached pictures.
What goes wrong ?!
What can I do now ?
PS: The raspberry is still working fine now that I removed the HifiBerry.
