Look at the procedures for Code Search at the following link:

Before you start pairing, however, I'm curious why you're using optical. What's the make model of your LG TV?
thank you for the response. I did use the cox link and followed all of the code searches, plus looked on line for more codes. Nothing worked.
The tv is a new LG 2020 model, OLED65CXPUA,
The input was set up the Best Buy installers. From the television the Optical Digital Audio Out is used to the sounder Optical In.

upon trying one more time, I find that once I use the Samsung sounder remote to turn it on, the LG remote will increase or decrease the volume, but the Cox remote will not.
THE LG remote will not turn the sounder on, however. And neither will the Cox remote. Perhaps Samsung has discontinue this model of sounder and no longer supports the codes or whatever...I don't know, just guessing.
