How do i enjoy 5.1 surround sound without having an optical cable on the back of the main unit?

I have a ps3 and i want to connect it by optical cable to the back of the surround sound unit. My surround sound main unit doesn't have an input for this but i was wondering if there was another way around it still achieving 5.1?



The connections on the rear of the surround sound unit include:



Audio in (aux)

Video out

Scart.



That is it.



So is there a way to get 5.1 through any of those using a converter?How do i enjoy 5.1 surround sound without having an optical cable on the back of the main unit?
There is no way to get 5.1 surround sound from PS3 with your system.How do i enjoy 5.1 surround sound without having an optical cable on the back of the main unit?
You have not just inputs to worry about, but PS3 outputs too. The PS3 can send audio in one of 3 ways.



1.) HDMI

2.) Optical

3.) RCA stereo



Since your receiver doesn't allow for options 1 or 2 the only way you can send the audio is via RCA. So until you get a better receiver you're stuck with 2 channel audio.How do i enjoy 5.1 surround sound without having an optical cable on the back of the main unit?
the way i did it was by using an audio out from my tv into my surround sound aux input.
