HiFiberry Digi+ Raspberry Pi3B Home assistant (Hassio)

Hello,

I've just bought the HiFiBerry Digi+ and installed it on my raspberry Pi 3B on which Home assistant OS is installed (HASSIO).

I followed the configuration from HiFiBerr's website as followed :

Remove dtparam=audio=on

Add dtoverlay=hifiberry-digi

I also tried with and without the additional line 

force_eeprom_read=0

 

When I execute ha hw audio, I have this result :

audio:
input:
alsa_input.platform-soc_sound.iec958-stereo: Built-in Audio Digital Stereo (IEC958)
output:
alsa_output.platform-soc_sound.iec958-stereo: Built-in Audio Digital Stereo (IEC958)

Can you confirm that it's correct so far? I would have expected to have someting mentionning HifiBerry or something.

 

Then when I configure home assistant to use this output, I can select Built-in Audio Digital Stereo (which seems to be correct), but when I play a file, there is no audio (it was working fine with the jack output).

 

If you have any idea what I need to correct, please let me know.

Thanks,

Aurelien

  I don't have a fix, but am currently attempting the same thing as you.

  Can confirm that what you're seeing isn't correct:

  On Raspbian, where the card works, there is indeed a HifiBerry output listed in the alsa devices list

  When dtparam=audio=on is added, an additional output device for the 3.5mm jack is visible: alsa_output.platform-bcm2835_audio.stereo-fallback: Built-in Audio Stereo

  Therefore, this output confirms 3.5mm jack has been disabled, but the HiFiberry hasn't yet been recognised. Don't understand why, as there are definitely hifiberry-digi and hifiberry-digi-pro device overlays in the overlays folder.

  I'm going to continue playing around too in the hope of finding a fix, will let you know if I find anything. Hopefully someone else can chime in with a fix though.

  So did anyone get this working? Looks like I have the same setup. Any tips?

  I have a similar problem on RPi4 with HiFiBerry Digi2 Pro.

  Home Assistant (hassio) does not see the audio output device.

  There is information that this works out of the box on the HiFiberry DAC. And Digi does not work for anyone ...
  https://community.home-assistant.io/t/hifiberry-with-spotify-connect-on-hassio/87180

  I mounted microSD on PC and changed in /boot/config.txt:

  dtparam=i2c_arm=on
  dtparam=i2s=on
  dtparam=audio=off
  dtoverlay=hifiberry-digi-pro

  OS Version: Home Assistant OS 7.0

  Same/similar issue here.

  Can't get Digi+ to show up as an option in Home Assistant Spotify Add-On.

  Any idea on how to fix this would be very much appreciated.

  There seems to be some recognition, as the HA audio log is filled with:
