I tried the latest test image on both a Raspberry Pi 2 B, and on an A+. Both times I got a message "module snd_soc_hifiberry_amp not found". Also, I hear nothing on the loudspeakers.
Is the test image broken, or is my Amp+ faulty?

HiFiBerry team Hi Martin,
this looks like the test image doesn't have the Amp module included. We tested the Test image only with the DAC and Digi boards yet.
Best regards

martin3 The problem is this: No matter what Linux image I use, and no matter on what Raspberry Pi I use the Amp+ on (A+, Model 2), I always get an error -517 when the Amp driver tries to load.
This basically means that no board is being detected, as far as I know.
I do power the Pi through the 12V connection of the Amp+; I would expect the error -517 if I power the Pi directly and leave the 12V unconnected.
Also, on the Digi+ and on the DAC+ I see an LED being lit up as soon as the board is enabled. I never saw a LED on the Amp+.
I think that the board is broken. How do I go about replacing it? -
martin3 I am getting more and more confused... I now manually configured everything on a plain, fresh Raspbian image. The driver still reports -517 when the Raspberry Pi boots up.
Without much hope I tried "mplayer", and heard a sound! There is still no LED, but I guess that's normal.
So: Why is this "-517" message on boot? The exact messages are:[ 4.860766] snd-hifiberry-amp sound: ASoC: CPU DAI (null) not registered

HiFiBerry team Hi Martin,
there is no LED on the board. That means it is not broken. The error 517 is ok, this happens when the underlaying driver is not yet loaded. The important line in the log is:
snd-hifiberry-amp sound: tas5713-hifi 3f203000.i2s mapping ok
As playback with mplayer is working now, I think everything is ok.
Best regards

martin3 Yes, it's ok. Meanwhile I have Runeaudio flashed to the SD card, and it works fine.
In the end it was a simple mechanical problem: Apparently at least one cable per loudspeaker was not making good contact.
Because of "no LED", and because of the error messages, I never suspected such a simple problem.
The Amp+ sound great, by the way. -
HiFiBerry team Godo to hear this.
Enjoy your sound!

armyofmike Hey everyone-
After noodling around with Volumio and getting no sound, I attempted the test image. I am unable to hear any sound from the test image.
Setup:
- RPi 2
- Amp+
I have confirmed that the wiring to the speakers are correct, and also confirmed that the speakers are operational. Power supply is 12v 2a to the Amp+. Am I missing something obvious?
Thanks,
Mike
