HDMI Audio on edge kernel for Orange Pi 5

[mitu]

I have an Orange Pi 5 board, installed with the 25.8 Debian Bookworm + Cinnamon desktop system. I have switched (using armbian-config) to the edge kernel in order to test the HDMI audio support in the new Linux kernel, but I'm not getting any audio out. The ALSA HDMI card seems to be present (see below), but there's no sound using speaker-test or aplay.

I have enabled the hdmirx overlay through armbian-config also, but the result is the same.

 

Is there anything extra that should be configured in order to get audio output ?
