you will need a sound bar/or speakers for the toslink to hook to for the sound
you can buy the toslink anywhere you can get it, the amazon link was just example
This is how mine is hooked up, since most "NEW" TV'S have lousy or no speakers at all
Soundbar is the Best way to Go, since your HDMI port for sound maybe Hooped or a different TV
You have to get sound from Jynxbox "TO TV" first, how you output the sound from TV can been done by
the different hookups you have (audio-out). The other way would be to hook like a dvd recorder in between
Jynxbox to Recorder out to TV or some kind of video/sound switch hub, something like this:

HAVE to find which one is the problem first J-BOX OR LG, Try hooking the J-BOX to another TV with HDMI
ONCE you know which one is the problem, then proceed from there on "HOW" TO make it work.
I don't have a J-box, have a SV8000, just offering suggestions on what May Work
toslink won't work if the TV isn't getting the digital audio through the HDMI
the sound has to come from the jynxbox
so if your jynxbox has an optical out connector then you could use a toslink cable to connect the jynxbox to a soundbar
Try a different HDMI cable, this thread is 4 yrs old.
