My English is not perfect, but I hope you understand what I want to do. So here is my problem, I hope you can help me: I have a SB Audigy 2 soundcard with the CL-driver installed, but I think about using the kx-driver. Would it be possible with using the kx-driver to decode an ac3-signal from a software-DVD-player with the Audigy2 and use ac3-passthrough at the same time? I want to have my home theater decode the "raw" ac3-signal to 5.1-sound and simultaneously use headphones. When I let the Audigy decode the signal, I don’t have 5.1-sound at my home theater (only digital-in) and in ac3-passthrough-mode I don’t hear anything from my headphones.
