Can my TV support surround sound audio somehow?

[SuperMariooooo]

Hi everyone, I was hoping someone here could help me out.

I've got an LG 50LN5400 TV, and I'm looking at getting a sound bar for it. Is there any way it can support surround instead of stereo? Considering it only has RCA and headphone outs. No optical or coaxial. It has 2 HDMI ports but it doesn't seem like they have ARC.

If I connected a Blu-ray player and Xbox for example, to a soundbar via hdmi in, and hdmi out from the sound bar to my TV's HDMI in, would that work?
Alternatively, would I need an AVR or something? A bit confused with all the sound alternatives out there..

Thanks for any help you can provide

Shows there that it has optical and coax out.

That's very weird.. The European version might have changed the connections? Either way mine doesn't have coax or optical I'm afraid

Then it's got an HDMI, headphone out and a USB input on the side

Not many soundbars support multiple HDMI inputs. If you can afford it, the best bet is a AVR reciever. Then you can plug in all your things HDMI into it, strip the sound from the signal and pass the video to the TV.

Oh ok I see, well for now I think I'll settle for just using stereo, but thanks a lot for the help!
One last question, what would I use from the AVR to the TV? HDMI out of AVR to HDMI in on TV?

Yes. The AVR would have an HDMI out that would go into the TV.
