Hello, All I'm sorry for this question, I know that everyone is fed up with it, and it was asked several times. But I want to get it clear once and for all. I have a receiver and I used it as a decoder with Creative drivers (I've Creative 5.1 SB0220). It means that DTS or Dolby Digital went through spdif without decoding in PC, and then receiver decoded it and sent to speakers. I can't do the same with kxdrivers because they do not support ac3passthru. Am I right? Thank you in advance.
