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 :
I also tried with and without the additional line
When I execute ha hw audio, I have this result :
alsa_input.platform-soc_sound.iec958-stereo: Built-in Audio Digital Stereo (IEC958)
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.
