No sound on n150, tried everything I can think of

Yesterday I spent about 4 hours trying to get Libreelec installed on this mini PC.
The mini PC has 2 HDMi ports, as well as a Display port.
The TV (Philips) has a HDMI ARC and a regular HDMI port.
(for now the device is just connected to the Philips TV, without soundbar.
It will be replaced by a LG/TCL/Hisense in the future)
I have tried 6 or 7 HDMI cables.
In Windows, everything works, connected to either HDMI port, using any of the tested cables.
In the past I did plenty of installations of alls sorts of Kodi related OS-es on different devices.
Currently I have W11 installed on it, but since I am only using the dvice for Kodi in the bedroom, I thought I would 'upgrade it with LE'.
Luckily I was smart enough to first check to see if, running from USB in RUN mode, everything is working as expected.
I can create USB sticks that boot, no issues at all.
In Kodi, I can set network, connect to wifi, or wired.
Kodi is exactly working as it should, but here comes:
I set the system settings to expert.
In the audio setup menu, I can choose:
ALSA HDA Intel PCH, PHL Philips FTV on HDMI #0
ALSA HDA Intel PCH, HDMI #1
ALSA HDA Intel PCH, HDMI #2
ALSA HDA Intel PCH, HDMI #3
And some formats for pulse or bluetooth audio
I tried all stable versions from kodi 21.2 - 22.0 piers
I tried several nightlies
I tried to set the sound format to optimal, fixed, etc.
Checked if Kodi wasn't muted.
Did cold boots on Tv as well as the mini PC.
Honestly, I am completely lost.
Am I doing something wrong?
What version is supposed to work with the N150 chip?
