How to connect soundbar to LED TV without any audio out

[sgpg98]

I bought a LG 32LF510B LED TV and I want to buy a soundbar, but I still haven't because I noticed this TV doesn't have a headphone jack nor LR audio out. I know I can use a scart RCA adapter, but I use my scart entry A LOT. I plugged my TV box through scart and my PS3 through HDMI, leaving me without more entries. If I could simply plug the soundbar to the TV, I wouldn't have to worry about anything, right? Also, my budget is kinda low and I can't buy those 4x1 HDMI switchers with audio out because they are more than $30. What are my options?

Specs on the lg site say it has a 3.5mm headphone out mate ??
