I just bought the Creative Audio 2 ZS with the front panel and I have used the optical digital and the coax digital outputs to feed the audio through my receiver but I continue to only get 2 channel stereo. What am I doing wrong here. I am using the same inputs into my receiver that I normally feed my DVD digital into and get either Dolby Digital 5.1 or DTS 5.1. However, it is saying PCM 96 instead on my receiver. How can I get this to feed the Dolby or DTS signal in so it can be decoded. The cound card supports both DTS and Dolby. Thank you.
