I recently bought this sound card. Quick question though. I am building HTPC, therefore I need good audio to my receiver. Anyway, here is my question. When you put in DVD movie to dvd-rom, it convert the audio to analog then send it to motherboard. Assuming, you dont have sound card here. Unless you connect dvd-rom SPDIF to motherboard SPDIF and your motherboard has optical out. That way, you can get digital from source going out to receiver. Since, if you have soundcard now, which is pci bus. So, the audio source from above sinerio gets convert to analog at some point? Or the audio go straight to sound card with out converting to analog? Also, there is no SPDIF connection on this sound card.
