Simply for troubleshooting purposes Leo, can you hook up some speakers or headphones to the audio-out port on the Pi, and see if any audio is present there? You might also need to unset that AUDIO_OUTPUT Device Variable that is currently set to RPI_HDMI0, and reboot. I realize it’s not what your end goal is, but, I am curious to see if that works, and can at least confirm audio works in that scenario… Also, I see that other user that Kyle linked to has a similar problem. I will try to do a fresh build and see if I can duplicate this behavior myself, as well. Thanks!
