Looks same as for CE. No idea why it doesn’t work.
Btw: /flash/sc2_s905x4_4g_1gbit.dtb is not needed.

Not sure if it helps but here I compare Ugoos and Vontar

the fe01a000.t9015 mapping

actually
if I apply auge_sound section of the ugoos patch and build dtb sc2_s905x4_4g_1gbit
then analog audio does work just fine 
!
#include "sc2_s905x4_2g_1gbit.dts"
/ {
coreelec-dt-id = "sc2_s905x4_4g_1gbit";
memory@00000000 {
linux,usable-memory = <0x0 0x000000 0x0 0xf1000000>;
};
auge_sound {
avout_mute-gpios = <&gpio GPIOD_2 GPIO_ACTIVE_HIGH>;
aml-audio-card,dai-link@1 {
codec {
sound-dai = <&amlogic_codec>;
};
};
};
};
&drm_vpu {
logo_addr = "0xf0800000";
};
and (note fe01a000.t9015)
VontarX4:~ # dmesg | grep -i auge

So this fixes problem, but, is it sc2_s905x4 generic or does it need a separate dts?
I am somewhat of a n00b and propose experts find the exact spot to patch CE 
I didn’t use avout_mute-gpios that’s why it works with your complete changes.
We need to think how to apply this change - to think if can be used generally (probably not) or only for Vontar (which doesn’t have separate dtb).

I believe to see in Vontar shop all X4 models have 4GB RAM and 1Gbps Ethernet. Different models only differ in storage 32|64|128 GB.
So a separate sc2_s905x4_vontar_x4.dts derived by including sc2_s905x4_4g_1gbit.dts might perhaps be safe.
The hardware works well for CE ne, though I have no opportunity to test optical audio so I cannot speak for that part.
I never was able to get analog audio out working in CE on any of my ah2xx devices so I am not sure it is just Vontar
What I meant to say is that I don’t know if a change is good for all devices. It can help but at the same time it can broke some other devices. Who knows.

fwiw: following Vontar X4 specific sc2_s905x4_vontar_x4.dts seems to do well
(Makefile needs update as well)
#include "sc2_s905x4_4g_1gbit.dts"
/ {
model = "Vontar X4";
coreelec-dt-id = "sc2_s905x4_vontar_x4";
auge_sound {
avout_mute-gpios = <&gpio GPIOD_2 GPIO_ACTIVE_HIGH>;
aml-audio-card,dai-link@1 {
codec {
sound-dai = <&amlogic_codec>;
};
};
};
};
I tried to create a pull request on github to support Vontar X4 and fix Vontar X4 analog audio but I have no contributor status. Would anyone perhaps consider committing this new sc2_s905x4_vontar_x4.dts file? All Vontar X4 have 4GB RAM and 1Gbps Eth, so (apart from storage) are identical.
any news in this update i have same problem

no loque dont work, ken you post yours.
I think tasinofan needs to tell exactly what is needed.
It is based on this

this first post loques different
using this one CoreELEC-Amlogic-no.aarch64-21.0-Omega_nightly_20240103, the audio works, dont no if it helps
With which DTB?
White The One its comes white it, sc2_s905x4_4g_1gbit.dts
I don’t see what can be wrong. I hope tasinofan will help again and I will push the changes to repository for NE device.
