Solved! How do I output audio from my LG 43LF540V to Samsung HW-K450 soundbar directly?

Nov 29, 2018
My tv does not have any outputs, other than SCART and PCMCI (not sure if this can output).The manual says TV Out : Outputs Analogue TV or Digital TV signals.
Would I need an active converter to HDMI?
Also, are there hdmi "switches" of some sort? I already use the single HDMI inout of the soundbar to link my PC, so given I manage to get output from the TV I'd like to switch between sources without having to change the cable.
