Sorry, but saying moOde has its own kernel seems a perverse answer; moOde is built on RaspiOS and uses the kernel shipped by the Raspberry Pi Foundation.
Here's a snippet of alsacap output from my RPi4B. It says the HDMI device can output up to 8 channels.
Having said this, I've exhausted my knowledge of the subject.
Threads such as Crackling audio when playing 5.1 FLAC over HDMI would suggest others are more knowledgeable.
