Hello there,
I’m currently facing a problem with my Amp+, which is falsely recognised as DAC+/ not recognised by my Raspberry Pi, depending on the used Raspbian image.
My hardware:
- Raspberry Pi 3 Model B V1.2
- HIFIBerry Amp+ 1.0
- Powersupply: Mean Well 18V/3.33A (the one from your website)
- MicroSD card
If I use the Raspbian Image from the download-section here, my amp+ seems to be recognised as dac:
aplay -l shows:
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
after adding dtdebug=1
to /boot/config.txt, and reboot i get with dmesg

But if I use the current plain Raspian Stretch Lite Image from raspberrypi.org and changing in /boot/config.txt:
- delete:
dtparam=audio=on
- adding:
dtoverlay=hifiberry-amp
and after reboot no soundcard is detected:
aplay -l just shows:
aplay: device_list:270: no soundcards found...
and with
dmesg
i got:

Since I read about defect microSD cards I bought a new one and experienced the same issues. I also bought a new power supply, because sometimes I see a "Undervoltage" warning on booting the RPI and in some of this cases a reboot. But I suppose this problem only occurs, when i connect a monitor via HDMI. And I remounted the Amp+ several times new on my Raspberry to check if there only some loose connections (?).
At this point I assume a hardware problem, but I don't know if this is the RPI or the Amp+?
And I don't understand why I get different results, depending which image i use?
And here a image of my setup:
