Hi guy.

I have a RPI2 with Amp+ on Archlinux arm. But, I have this line on dmesg:

snd-hifiberry-amp sound: ASoC: CPU DAI (null) not registered
[ 12.652138] snd-hifiberry-amp sound: snd_soc_register_card() failed: -517
[ 12.661206] snd-hifiberry-amp sound: ASoC: CODEC DAI tas5713-hifi not registered
[ 12.672484] snd-hifiberry-amp sound: snd_soc_register_card() failed: -517

 

I have a /etc/modprobe.d/blacklist.conf file with the blacklist module. And this is the content of /etc/modules-load.d/raspberrypi.conf:

bcm2708-rng

 

Thanks for help.

  What kernel version are you using and what exactly did you configure?

  Hi Daniel, and thanks for your report

  I don't have my raspberry on my work ^^, but the kernel version is 4.1. For configure it, I follow instruction from this link: 

  https://www.hifiberry.com/guides/configuring-linux-3-18-x/

  For the moment, my speakers is not connected to the amp. Moreover, lsmod command display the correct module for amp.

   

  Thank you very much

  Some files might be at different places on ArchLinux, it is still possible that not all modules are loaded. Please post the output of lsmod.

  Best regards,

  Looks like at least the i2c module is missing (most likely blacklisted somewhere).

  Hi guys, sorry for late. So, the amp+ is now recognized ^^.

  I have installed the i2c-tools and add the following line on /etc/modules-load.d/raspberrypi.conf:

  i2c-dev

  i2c-bcm2708

  But the last module is blacklisted (if you following the instruction: https://www.hifiberry.com/guides/configuring-linux-3-18-x/) so I have comment the line.

  After that, aply -l show:

  **** List of PLAYBACK Hardware Devices ****
  card 0: sndrpihifiberry [snd_rpi_hifiberry_amp], device 0: HifiBerry AMP HiFi tas5713-hifi-0 []

  Thank

  Jean
