Hi guys,
I would like my box to only output audio to spdif.
I have box with Android 5.1.1 in the digital sound settings I can select spdif only.
On libreELEC the option passthrough output device is grayed out, I am getting audio from my TV (HDMI) and my Audio Receiver (SPDIF).
Is there a way to have spdif audio only?
Thanks !

Did you activate passtrough "Allow passtrough"?
Did you activate passtrough "Allow passtrough"?
Hi Vitorp07,
Yes I did
I selected and de-selected the option. I am in expert mode.
With "Allow passtrough" activated " Passthrough output device" is still greyed out?
Try switching the "Audio output device" to see if it stays the same and don't forget to adjust the "Number of channels"
Do you have the option "sync playback to display" enabled? If so that will disable passthrough
If you're on Krypton you can forget about passthrough. Also if you're using an Amlogic box audio is output to all devices simultaneously.

Hi Guys! thanks for the help!
I do get audio simultaneously on SPDIF and HDMI 
Is there a way to get the SPDIF output only?

The option I have as output devices : ALSA: AML-M8AUDIO, PCM
ALSA: AML-M8AUDIO, HDMI

"sync playback to display" is not enabled,
Any suggestion I should re-search on maybe the DTB file is wrong?
Check that Settings-System-Audio-Output configuration is not set to Fixed.

Why?
Why?
You will only get passthrough with local files. Kodi devs claim that there is no way to properly sync audio/video with passthrough enabled for livetv. People report this is the same for streams as well.
Search the Kodi forums for the details, but it's just a lot of users pulling their hair out and devs claiming that working passthrough on 16 was just a fluke.
This alone will keep a lot of folks on Jarvis for quite some time.

OK!
Thanks for the clarification!

Thanks you all! For the tips 
unfortunately it still grayed out.
The output configuration was set to optimized, I have tried to switching to Best and even Fixed but there was no change as suggested by Doug.
If I boot into android the output Device is: Android , audiotrack and not ALSA: AML-M8AUDIO, PCM or HDMI.
Could it be my device tree?
Here is some more info on the state of audio on 17 -> PVR without AC3?
