HDMI audio format support is something that the Raspberry Pi guys own.
I could only find a few recent posts that discuss 24 bit audio over HDMI and there does not appear to be a solution other than some videocore driver and config hacks that don't universally work...

I'd recommend posting an issue in the Raspberry Pi Linux git
https://github.com/raspberrypi/linux/issues?q=
Mention such things as:
- Kernel version: "uname -a"
- RaspiOS Lite version: "cat /etc/debian_version"
- ALSA version: "dpkg -l | awk '/libasound2:/ { print $3 }'"
- Output from the "alsacap" command showing the supported audio formats for HDMI interface
- Contents of /boot/config.txt via the "cat /boot/config.txt" ciommand
