Hi dev experts!
My device is Sammix R95s motherboard info BX905X_V1.0 (2016-08-17) MS-M1 E198407
CPU type S905X, 2G Ram
Resolution 1080p, Refresh rate Default setting
Installation is external
I am currently using LibreELEC-S905.arm-9.0-devel-1522452099.img.gz
The DTB file used is gxl_p212_2g.dtb
I would like some help on figuring out why the toslink(optical) is not working . Under android 6 the optical works.
Now when I try under LibreELEC I see the red light and no audio what I tried so far.
My setting are:
Audio passthrough on
Dolby Digital (AC3) capable receiver on
DTS cable receiver on
...
Sync playback to display off
What I have noticed when I set audio passthrough to on and then play a test file I get no more audio via hdmi. When I set passthrough back to off I don't get my audio via hdmi I need to reboot the box.
GDPR-2 do you think the optical out issue is because I need my own dtb file?
Big thanks
