The only audio formats optical supports are
1) PCM 2.0 (stereo)
2) Dolby 5.1
3) DTS 5.1 (not supported by LG).

So that limits you to stereo PCM and Dolby 5.1, nothing can change that on the C1.

On LG sound settings change the digital sound output from PCM to Auto so it can pass Dolby 5.1, on your console set it to bitstream Dolby 5.1

Fixed! i'ts seems tv has a bug changed from optical out device to HDMI(ARC) and then back to optical out device then i was able to change digital sound output from pcm to passthrough and now receiver is showing dolby D
