Solved! How to connect non HDMI arc TV to a HDMI arc home theatre?

[aksplod]

Kindly help me to connect my TV to the Home theatre. I have VU49D6575 tv without HDMI arc nor optical ports. It has the colourful RCA ports though. I bought a new Sony Home theatre HT-RT3 with HDMI arc and optical ports only. How do i connect both such that i get sound from the home theatre?
