I have used hdmi sound but now I have a need to use the analog audio jack. However, I do not seem to have one in KDE Plasma (arm-unstable).
$ inxi -Fazy
Audio:
Device-1: bcm2711-hdmi0 driver: vc4_hdmi bus ID: N/A chip ID: brcm:fef00700
Device-2: bcm2711-hdmi1 driver: vc4_hdmi bus ID: N/A chip ID: brcm:fef05700
Sound Server: ALSA v: k5.10.9-1-MANJARO-ARM
And amixer does not show an analog option.
Maybe related to these messages?

But they seem to reference HDMI, which works fine, so maybe not.

I have messed around with:
$ amixer cset numid=3 [1-4]
But they result in setting the volume to 0, no change in output device.
