Hello everyone!
My sound is only output via hdma, there is complete silence via spdif. And I need spdif specifically Any ideas on how to fix this?
My tv-box is H96 max x3, I boot up via the Ugoos x3 device tree.
Who has sound via spdif on a tv-box with Armbian? On which tv-box exactly?

I'm not aware of this working on any boxes I have.

This can be done on S905X3 boxes "tested on the X96AIR-GBIT and H96MAX", but it would require patching the DTS files and applying the correct mixer settings.

 

	amixer -c 0 set 'TOHDMITX' 'on'
	amixer -c 0 set 'TOHDMITX I2S SRC' 'I2S B'
	amixer -c 0 set 'TDMOUT_B SRC SEL' 'IN 0'
	amixer -c 0 set 'FRDDR_A SRC 2 EN' 'on'
	amixer -c 0 set 'FRDDR_A SRC 3 EN' 'on'
	amixer -c 0 set 'FRDDR_A SINK 1 SEL' 'OUT 0'
	amixer -c 0 set 'FRDDR_A SINK 2 SEL' 'OUT 1'
	amixer -c 0 set 'FRDDR_A SINK 3 SEL' 'OUT 3'
	amixer -c 0 set 'SPDIFOUT_A SRC SEL' 'IN 0'
	amixer -c 0 set 'ACODEC' '85%'
	alsactl store

 

Can also boot with mainline u-boot on them, but you would lose the ability to easily go back to Android.

 

The patch I use for linux 6.6.y;

 

004-arch-arm64-dts-amlogic-meson-sm1-ac2xx-tv-boxes.patch

@c0rnelius  Have you submitted those dts patches upstream? and/or should they be added to Armbian?  I don't have those boxes so I can't test, but maybe helpful to others.

Nah. I haven't submitted them. I've considered doing a PR to Armbian, but just never did as I'm honestly not sure what the state of things are on the Armbian front when it comes to TVBOXES.

 

Well, I'm keeping the Amlogic TV box builds alive as I have a bunch of personal servers running on that hardware.

Well you are more than welcome to use what you want from the patches for S905X3. I've only run tests on the ones I have of course, but the SPDIF and ANALOG are identical on both. I suspect they are probs generally the same on most of those BOXES.

Can someone share a ready .dtb file with this patch.

I am trying to run SPDIF in Tv-Box Vontar X3 with Amlogic S905x3 processor
but I can't compile with this patch.

I forgot to write that I use meson-sm1-x96-air-gbit.dtb.

Kernel 6.12.31-current-meson64.

Please provide a .dtb file with working SPDIF.

It may be a different kernel version.

If I had any .dtb file with working SPDIF I could modify my file using the "fdtput" command.

TV boxes are Community supported.  That means they are not supported by Armbian.  It is up to community members like you to figure these things out and submit them back to the community through your contributions.

So I understand that no one will help me because I am not a programmer.

And could you tell me how to add a patch to my .dtb or .dts file.

I installed linux-headers but I don't know what to do next with the patch posted above by c0rnelius.
