No Spdif device in system settings

It was the first installation on my box.
-Etcher to get the img on sd card (class 10)
-Copied the dtb and remote files according to the guides in this forum
-Booted via toothpick method

No addons were installed. After your reply I updated to nightly build without any change.
Spdif does not show up in the audio settings.

Can you try just plugging in the Spdif cable to see if you get audio out?
It tends to just work on most systems, since it’s output is set as a duplicate of the hdmi audio out.

Booted with just the Spdif cable inserted. It does unfortunately nothing just as pulling the hdmi
cable during playback. Always no audio. Btw the Spdif is coax with RCA (looks like a headphone jack) on the MXQ Pro 4k box side.
I already tried older versions of LibreElec (8.3.2.1. and 8.0.2e) and reinstalled the latest stable
version of Coreelec afterwards. Each time only 3 audio options are available:
ALSA: Default (AML-8AUDIO Analog) PCM
ALSA: AML-8AUDIO HDMI
PULSE: Default Bluetooth Audio (PULSEAUDIO)

Audio over PCM and HDMI works now It must have been the coaxial cable.
Thanks again to everyone who was trying to help.

Any idea? I have the same problem. On LibreElec/CoreElec.

First, start by reading this easy KODI guide - Audio quickstart guide. Then tell us about your setup. Is your box connected directly to your TV or your AVR?

If you don’t figure this out in the next 48 hours I’ll look into it by connecting my box to my AVR or/and TV with S/PDIF to see if there are any issues with the build.

Yes, I have it, and I have this https://kodi.wiki/view/Settings/System/Audio too.
I have only these choices.

I have debug log here kodi.log (87.7 KB)

Thank you.

@ac3 have you tried just plugging it in and seeing if you get sound through the spdif connector without changing any audio settings from the default configuration?

I tried now and didn’t help it.

The way the audio is currently setup the hdmi, any onboard dac and spdif get the same audio. so as long a you are using the correct device tree for your device it should just work with the default out of the box configuration.

I’ve tried all kinds of CoreElec even older LibreElec and in or one it does not work.

What device do you have? Which device tree/dtb file are you using? coaxial or toslink cable?

I have SCISHION V88 PRO 1/8 with ArmLogic S905X with toslink cable and I use gxl_p212_1g.dtb

According to here, your device has Coax SPDIF, so by design cannot work with (optical) TOSlink cable…

I used this converter https://www.aliexpress.com/item/Hot-Toslink-Plug-to-3-5mm-Mini-Digital-Optical-Cable-Adapter-Male-to-Female-Fiber-Optic/32820730128.html?spm=2114.10010108.1000023.4.64172d1cHSAx97 for optical cable…About I it broke down?

Here is written that is an optical S/PDIF
The SCISHION V88 Pro TV Box is well and solidly made of good quality plastic in black. Top housing is a matt while the sides of the device are shiny. As we wrote at the beginning of his heart is Amlogic S905X Quad Core ARM Cortex-A53 CPU up to 2GHz which supports 4K HDR, 4K VP9, H.265 10-bit 4K*2K@60fps and HD Audio (7.1CH) passthrough. Device runs on Android 6.0 Marshmallow . The front panel has IR receiver and power LED. On one side is a three USB 2.0 ports and SD card slot. On the rear panel are: another USB 2.0 port, Optical S / PDIF port, AV port, HDMI 2.0 port, RJ45 Ethernet port and 5V/2A DC jack.

It’s a simple mechanical adaptor for Toslink, so I don’t think it’s broken.

Yes, that’s strange…
I checked for some pcb pictures, and according to here and here it looks like a coax SPDIF, as there is only a standard 3,5mm jack placed.

Also the seller here confirms that it’s only coax:


Thank You so much for the information, I’m going in search of what to do.

You need an active Coax to Toslink adapter.
