Raspberry Pi 4 No 3.5mm sound using balenaSound

Project help balenaSound

Hi!
Everything seems to be working apart from the actual playback of the sound. In the logs I get the error “audio WARNING: BCM2835 audio card not found, are you sure you are running on a Raspberry Pi?”. Yes I am and I have something connected to the 3.5mm jack, but it still does not play audio through it. I do not have a mini HDMI adapter to check if the HDMI works, but I could see that before I set the configuration to ignore them, in the logs it was detecting both HDMI outputs. How can I fix this issue? I have already set AUDIO_OUTPUT to the headphones option, and set BALENA_HOST_CONFIG_hdmi_ignore_edid_audio to 1, but this only makes the “audio card not found” error display.

I hope you can help me here
Eddie
