Since (I guess) you have opened the PS3, look around the mainboard for blown components, such as capacitors. I am almost certain you will find 1-2 blown there. When you do, you need to replace them and you will get your sound back.

ohhhh thnxx dude but umm how do i tell if there blown wat am i looking for n if i find it can i bridge it or sumthing ?

Usually the capacitors are swollen or have burn marks on them. When you locate such issues, you must replace them with equal valued components.

okaii understood but now i dont see any burnt or swollen all are fine :/

Then you are in big trouble.... can you post photos of your board? also make a focused one oon your ports.

what u mean big trouble ? and okaiii i will

Big Trouble means that your problem might be a chip or regulator, not a simple capacitor and they are hard to check and be replaced (is hard to find them in the market)

ohhhhhhhhhhhhh but is there any work around to get audio ?

Nope!
