Audio not coming out jack 3.5mm on RPi4

[saveriogzz]

Describe the problem Using a RaspberryPi4 and setting the env variable AUDIO_OUTPUT to either RPI_AUTO or RPI_HEADPHONES. Does not make the audio coming out of the RPi4's 3.5mm jack. Using the latest commit e3098287cb9b0b866e528251b424e388e3fbbb6a

To Reproduce Steps to reproduce the behavior:

1. Set the device as a STANDALONE and set the env variable AUDIO_OUTPUT to either of the two options above.
2. Try to reproduce music
3. Check result

Expected behavior I would expect the audio to work since I've tested it with RaspberryPi OS and the jack works so it's not a hardware issue.

I'm experiencing the same issue - everything seems to work, except the audio. Other than the above, I note the following in the log info shown in the Balena console. Release ed77d9d6afce9c1cb994476e8109142b

Update after seeing https://github.com/balena-labs-projects/balena-sound/issues/576#issuecomment-1133786126, I have cleared the "vc4-kms-v3d" value from the "Define DT overlays" option in the Device Configuration list. After a reboot, and restarting the airplay service for some reason, the audio from the 3.5mm jack is working.
