I have no sound on the rear speakers

[djolew]

I have samsung ht-thx22 home theatre. I connected pc to samsung with rca cable, to aux in, but there is no sound to the rear speakers, only the front (left, right, center, and woofer have sound)
Rear speakers work when the FM is turned.

Sorry for my bad english.

Computers do not normally output encoded audio for surround sound. Not hearing anything from the rear speakers is normal. To experience surround sound from the computer you will need to be outputting digital audio in an encoded format. Movies will usually play back with encoded audio if you have your playback software and your computer's audio playback device configured properly.
