Hi , i have panasonic th-l42u30m tv and Lg lhd657 home theater , i connect all wire with HDMI arc but i didn’t know how to make the sound come from the home theater , also the HDMI setting doesn’t appear in my tv .

i didn’t try the opticale cable because i have the HDMI , do you recommend that i use the opticale ?
 
The RCA is used in connection with the HDMI, it seems.
"Multi-channel sound
If you wish to enjoy multi-channel sound (e.g. Dolby Digital 5.1ch) via an
Amplifier, connect with HDMI cable and RCA cables (p. 53), and then select
