Logitech-X530 Problems

[trihedral]

I just bought this 5.1 surround sound a day ago and so far have trouble making the rear

and center to work.

I have a Dell Dimension 4700 using a onmotherboard sound channel.

Do i have to go buy a sound card to make the 5.1 work? Becuase i updated by sound driver to SoundMAx and it shows 5.1 surround as an option.

The Beep testing worked for the rear but when you listen to MP3 files it only uses the 2 ffront speakers. Center did not beep during the test

Please help Guys

Never mind, pluged orange cable into the yellow and tested positive. Surround sound does not work on all programs. Now i play MP3 on PowerDvD 7. Lets me set the audio from mono all the way to 7.1 Sound.
