How is your source connected (rca, hdmi)?

Is the source media definitely encoded with surround?

Do the source player and receiver *both* have either Dolby or DTS? You might try changing source from PCM to bitstream and see if it makes a difference.

Since we have no clue what make, model, or type of equipment you have the only advice is to check the owners manual. If there is a button on the remote that lets you cycle through the surround sound modes and you don't see one that seems to be 5.1 stereo then you don't have that mode.
