I checked spdif only when I add it. I assume this was for LE7. But didn't checked on LE8. Will do over weekend.

I found 10 minutes free time and check this: it works fine for me. Hope I connected everything correctly 
If I unplug spdif cable then sound is lost. When plug back sound is back too. Test successful.
And I was using official image with 4.4 kernel. With modified connector to correctly plug it in.
Currently addon doesn't build. I will try to fix it over weekend.
what does it mean : "and use parts from xoddark." ?
Build image with kernel 3.14
PROJECT=imx6 ARCH=arm LINUX_VERSION=sr-3.14 make image
and use parts from xoddark.
Update: Come to IRC and we can talk more directly.
Hi,
Just updated to LE 8.0.0 and it works...Even on the picture directory that would crash it every time...Looks like its fixed ... YEAH...great job...
Maybe it was fixed by itself 
Actually I didn't have much time to look into this issue. I could reproduce it with pictures send by spschneer and this is next thing to fix (audio not working immediately after boot is fixed but not yet included in the build).
You need both boot= and disk=.
Check what permissions are set on those folders to figure out what the problem actually is.
We only build LE on real Linux systems and not familiar with such environment.
all I get is a colored screen on my pi
Isn't this indication of bad power supply? Nothing related to problems here.
You need to set new UUID or use device name. Because when both devices are attached then kernel is used from one (boot) device and system could be used from another..
You could set new UUID from LibreELEC to unmounted device with command like
tune2fs /dev/sdXY -U $(uuidgen)On flash partition you need file uEnv.txt, KERNEL, SYSTEM and imx6q-cubox-i.dtb.
I think it is this file according to Zero2Nine user: /var/packages/WebDAVServer/target/etc/httpd/conf/extra/httpd-ssl.conf-cipher
I think you will have to change ciphers on your other 2 synology's.
What about removing volume label LIBREELEC on a created disk?
Own problem, own thread, own debug log please.
No need.
Seems for now only version with 3.14 kernel is not affected with this bug: LibreELEC-imx6.arm-7.95.3-sr-3.14.img.gz
Not yet tested (will do later today): LibreELEC-imx6.arm-7.95.3-sr-3.14.img.gz
This is version 7.95.3 with kernel 3.14 which doesn't have this sound start issue. At least initial tests shows that.
I'm still on 7.95.2. Will try out this and skip 7.95.3 for now since I had 3 fails with different installs.
Don't expect next version to be much better. With one guy touching basic things and the other doing basic testing you can't expect miracles.
7.95.3 had u-boot and kernel bump. Seems some things got broken.
10 steps back. Again...
