having a problem with my surround sound.

[Hikaru IchijoSL]

I can test all my 5.1 speakers in the windows 7 realtek hd audio manager. But when I go to play a dvd I only 2.1 sound even if I set the software to 6 speakers (powerdvd 9.5) and I have to set the sound level on my computer and speakers very high to hear anything.
