Hello,

since updating Raspbian from kernel 3.18.x to 4.1.x my AMP+ do not work any longer.

Output of dmesg:

[ 4.104962] snd-hifiberry-amp sound: ASoC: CPU DAI (null) not registered
[ 4.131003] snd-hifiberry-amp sound: snd_soc_register_card() failed: -517
[ 4.155931] snd-hifiberry-amp sound: ASoC: CODEC DAI tas5713-hifi not registered
[ 4.167622] snd-hifiberry-amp sound: snd_soc_register_card() failed: -517
[ 5.385820] snd-hifiberry-amp sound: tas5713-hifi <-> 3f203000.i2s mapping ok

Can you support me with installation / configuration instructions for kernel 4.1?

Thank's a lot!

  In general, the configuration is the same as in Linux 3.18 with device tree overlays. Did you already configure it as shown here:

  Yes I followed exactly the instructions on that link. And as I mentioned everything runs fine until the Raspbian update.

  aplay -l reports:

  **** Liste der Hardware-Geräte (PLAYBACK) ****

  Until there everything seems fine, but

  mplayer xxx.wav reports:

  The Raspian installation is up to date and clean. But it seems there is somethin not compatible?

  Any idea?

  What is your exact kernel version (uname -a) ?

  We have to test this in our lab. It is a bit strange that the latest kernel fails. However we have seen cases where an update of the kernel failed and the driver did not work without a clear indication what is wrong. In some cases, a fresh installation solved this. But let's check this first here.

  I'll wait for your results.

  Thank you for your effort.

  I had the same problem, but it went away when I added the following to  /etc/modprobe.d/raspi-blacklist.conf:

  blacklist snd_bcm2835

  I've the same problem also with the Kernel "Linux mediapi 4.4.13-v7+ #893 SMP Wed Jun 8 14:39:18 BST 2016 armv7l GNU/Linux"... Is there any solution for the Problem? I get no sound with my new Hifiberry Amp :(...

  I configured the soundcard as it is discribed here: https://www.hifiberry.com/guides/configuring-linux-3-18-x/
  And I also blacklisted the onboard soundcard...

  In "dmesg" I get this error:

  pi@mediapi:~ $ dmesg | grep hifi
[    7.368647] snd-hifiberry-amp soc:sound: ASoC: CODEC DAI tas5713-hifi not registered
[    7.368683] snd-hifiberry-amp soc:sound: snd_soc_register_card() failed: -517
[    8.487538] snd-hifiberry-amp soc:sound: tas5713-hifi <-> 3f203000.i2s mapping ok

  The dmesg output shows that your sound card is configured correctly. What exactly isn't working?

  I don't get any sound when I wanna listen to an mp3-File with smplayer. And what is with this message?
  --> 

  ASoC: CODEC DAI tas5713-hifi not registered

  and

  snd_soc_register_card() failed: -517

  When I had a look for this message, google tells me that I have to load any modules!? But I don't know which I have to load...

  These messages are perfectly fine. At the beginning, the modules have to be initialised first. The kernel does this and then tells you "mapping ok".

  I don't know smplayer. What is the output of it? I recommend using mplayer. It has all necessary codecs already included which can be a problem with some other players.

  Okay, smplayer also works with mplayer to play any music-files....
  Is it possible, that my boxes which are connected with the Hifiberry Amp doesn't have enough power to work? 
  I don't connected any powersupply-cable at the Hifiberry Amp.

  It get its hole power from the Raspberry Pi. And there is also an Display and an Arduino Leonardo connected with the Pi....

  Hi Matthias,

  if you haven't connected a power supply to the Amp+, you won't get any output at all. Check out this connection diagram:
