Question

Iron

TV LG has only one audio output (optical digital audio).
The LG music center only has one audio input (bluetooth).
Everything is geared towards transferring from the music center to TV (karaoke).
But I really want to amplify the sound on TV.
I ask for advice on a possible adapter or adapter system.
Himself with the technique on you.
Transfer the sound from optical digital audio to the bluetooth music center.

Answer 1

I have such a thing, it has optics for input and output, it can also connect to bluetooth devices, and you can connect to it. We take the optics from the TV set and direct it to the device, and connect the device to the music center.
There will be a delay of about half a second.

Of course, the music center must have a modern version of bluetooth that supports low latency, otherwise there will be a sound delay of half a second or so.
As an option, take a separate adapter that will make analog audio from optics, and then put the audio signal into a separate bluetooth adapter.
In general, some strange music center, without audio input ...
