NB: This script only worked for me from Windoze box running Python x86 when connected directly to LG Soft AP, steps below should get you connected just fine
- Start Soft AP on LG TV & connect PC to LG Soft AP
- Open script in Python & choose Run > Run Module
- Enter the Pairing Key shown on screen into the dialog box (OPT: add to Python script & save for re-use)
- Enter the codes above for the respective actions, but not the one and only thing I want: EZ_ADJUST;
My need is to enable Pass Through of 5.1 (6ch) audio from HDMI input to TOSLINK Optical output. At present any AV containing 5.1 sent to HDMI on the 42LA6230 TV is down-mixed to 2 (stereo) then sent out via TOSLINK Optical. Which means I can enjoy any media I want on my TV so long as:
a) I am happy to use the stereo speakers in the TV only, or
b) I am happy with only stereo audio on my HT surround system, or
c) I am happy to physically swap the TOSLINK cable from one source device to another each time I change what I am using

Answer to {a|b|c} = No
How To Access Service Menu On Lg Oled Tv
Many have stated that it is a simple on|off toggle in EZ_ADJUST to enable 5.1 pass through from HDMI to TOSLINK, but access to the service menu is required. I very much appreciate the work done to get this far, hopeful there may be something more we can do to expose/access the innards of LG TVs? I can't can believe they'd just hobble a function of the technology for market control.

For HDMI connected devices, in order for the TV to pass DD 5.1 you will need a service remote. In the EZ Adjust menu go to tool option 7 and change the EDID setting from PCM to AC3. TV will reboot and you will have full 5.1 pass through.
