I have the original baseboard as well. Let me have a look.
... I see the "hw:0,0 : HDMI fe400000.i2s-i2s-hifi i2s-hifi-0" audio device, is this the same for you? But it has no alsamixer controls. speaker-test reveals that it does not support many audio stream formats OOTB, so you might need to enable the auto-conversion plugin, e.g. via dietpi-config audio options.
I am a bit lazy currently to move around and attach an actual HDMI monitor. Let me know whether you see this device as well and whether the auto-conversion plugin helps, and in case if the "speaker-test" command produces output. If not, I'll have a closer look. Not sure if some kernel build flag is needed for additional HDMI PCM controls in alsamixer.
