Note 3.1 If you are using smart TV's HDMI ARC port, and your Sound output option HDMI ARC / Optical is ONE option, then your optical output will not work with HDMI ARC plugged in.
Fix - use other HDMI port, not the HDMI ARC.
Note 3.2 If your TV is very OLD and you use Roku, Fire Stick etc. for Netflix, Amazon Prime movies, TV optical port might not be compatible with latest movie audio format and hence no sound for those. (very rare)
Other General Troubleshooting Tips if No Sound after the following set up
