@zambu : I run NE standard Nexus CoreELEC-Amlogic-ne.arm-20.2-Nexus-Generic.img (from eMMC) on Vontar X4 with 4GB RAM and 1Gbps Ethernet with dtb.img sc2_s905x4_vontar_x4.dtb built on CE 20.2 git tag from own brew source in earlier post: Vontar X4 (S905X4): install to eMMC? - #28 by tasinofan

Analog audio works (3.5mm jack).

CE Audio output device is set to ‘ALSA:Default (AML-AUGESOUND Analog), PCM’.

Vontar X4 analog audio does not work on ne.aarch64-20.3-Nexus and ne.arm-20.2-Nexus
with provided sc2_s905x4_4g_1gbit, so on these branches CE team might consider adding a specific sc2_s905x4_vontar_x4.dts as given in Vontar X4 (S905X4): install to eMMC? - #28 by tasinofan

How come it works on no.aarch64-21.0-Omega is also a mystery to me and I should test it.

Keep you informed, but, of course, @zambu already tested

@zambu: please try this dtb for analog and let me know if works or not.
