I have just installed Debian 12 on a mini PC equipped with Celeron N3350. The goal is to use it for bluray playback. So far the video is smooth, but I can get audio only from the jack analog output.
aplay -l

So I tried
>aplay -D plughw:0,0 ~/Wav_868kb.wav
Playing WAVE '/home/roberto/Wav_868kb.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
and it gives sound on the analog jack output.
Using the same commands for 5,6,7 aplay -D plughw:0,5 ~/Wav_868kb.wav I hear nothing from my projector (audio-capable) connected via HDMI (it plays sound on this device using Windows 10).
I checked alsa-mixer and I cannot identify anything clearly "HDMI", despite /proc/asound/devices has theright devices
1: : sequencer
2: [ 0- 0]: digital audio playback
3: [ 0- 0]: digital audio capture
4: [ 0- 5]: digital audio playback
5: [ 0- 6]: digital audio playback
6: [ 0- 7]: digital audio playback
7: [ 0- 2]: hardware dependent

What do I do wrong here? what need to be fixed/verified to get HDMI sound out?
At the kernel level I do not see major issues, as seen below, but maybe I am wrong.
