Orange Pi 5(b) 3.5mm analog audio plug: no sound

[Thomm]

Has anyone managed to get Armbian on Orange Pi 5(b) output audio through the 3.5mm jack?

 

The device seems to be recognised, but even after fiddling with everything imaginable through alsamixer, with speaker-test running in the background, I am unable to actually get any sound out. HDMI audio works without any problems.

 

ChatGPT thinks it has something to do with GPIO routings not being properly set up. 

 

I'm running Armbian 25.2.3 noble (through `apt-get dist-upgrade`; I had to first install an older version from the archives to avoid bricking when installing on the eMMC).
