Are you sure your motherboard or sound card is capable of DTS?

Have you tried looking in the drivers?/reinstalling them?
What program are you using to test DTS?how are you testing it?using a file?a dvd?switching soundtracks?

Good thread since I had the same problem: DD played fine via the Vista Test Tones, but DTS did not even though I had selected the DTS checkbox. In fact, when I played DTS material on a DVD, my receiver display always displayed "Dolby DD" or "Dolby DD EX." Receiver is an Onkyo TX-SR 702 (supports DTS).
I am connected via optical from mobo's onboard sound to a receiver.
Resolved the problem though... whenever I play DTS material, I have to manually put the receiver in DTS mode (or DTS-Nero:6). Never had to do that when a stand-alone DVD player fed the receiver.
