No sound on RPi 4 3.5mm connector #594

Describe the problem After deploying I don't get any sound through the 3.5mm connector on the Raspberry Pi. I did not change any settings (so multiroom and automatic output are enabled) balenasound.log

What is weird is that the audio container only detected two HDMI audio cards, but the 3.5mm connector works (I tried it with another software).

Device information

Raspberry Pi 4B 8GB
16 GB microSDHC Class 10
balenaOS v2.103.1+rev1 (Production Mode)
- Supervisor v14.0.14

Thanks! As the issue suggested, just moving the lines

# Enable VC4 Graphics
dtoverlay=vc4-kms-v3d

to the end of the file fixes the problem.
