How to export audio from LG43LF5400 TV to 2.1 speakers while playing video from usb port? The 2.1 speaker has stereo female for audio in and TV does not have earphone socket or optical socket or RCA. I have tried scart to RCA but the sound comes out from 2.1 speakers only when channels are playing. When video from usb is playing the sound come out only from tv speakers.

This is a common problem with TVs where they play non-TV sound on the TV only.
You can get cheap Roku for your USB-base media, and connect it to both TV and soundbar

So there is not another solution with just cables... Thank you very much.

It is not a problem with the cables, but with TV' firmware. You might want to check whether there is new release which could enable that functionality.
