You can get that cable from eBay or any local Shop, and some are of poor quality, you should check them before you buy, as I bought 3 cables and all had loose connections, only one channel working, crackles etc...
Any particular brand you guys recommend...
So you found them in Reliance digi and croma
For your second query
check this i googled about that

pardon me for my noobness but this rca 3.5 got me thinking...so the rca cables will go at the back of the set top box and the 3.5mm jack to the music system...so now how do i expect audio to come when i connect a pen drive to my tv or so...do i have to then connect the 3.5mm jack to the tv & the speaker?
