Help a noob, to set up the sound, please.
 

Guys, can anyone tell me which setting I'm supposed to adjust so that if a movie is originally with DTS or Dolby Digital sound, this sound would be directly passed to the digital out of my sound card?

Right now I'm watching a movie, and the AC3 filter settings I see the following:
Input format: DTS
Output format PCM 16.
And there's a whole decoding chain...

The problem is - I don't want any decoding, my receiver can decode DTS and Dolby Digital sound on its own.
What do I do to have the DTS sound on my receiver unchanged?
