Hello all. I am trying to get an answer to a question that is bothering me. I have recently went back to PC gaming, and have been using my HTPC in my living room with a 360 controller. DMC just released and I noticed some things about the audio. My PC is always outputting PCM to each speaker. During the cutscenes everything is great. All of the vocals go to my center channel, and its nice and crisp. But when the gameplay starts its almost as if the audio levels drop a little but. Almost as if I was using Dolby Pro Logic. Everything just doesn't seem as crisp. So I was doing a little research and came across sound cards with Dolby Digital Live. From what I am reading it allows sources that are 2 channel, and decodes them into 5.1 on the fly. So each channel gets the right signal etc. Now my question is, is Dolby Digital Live better than PCM? My guess is no, because to my knowledge PCM is the output device sending each signal to the precise channels that are available. While Dolby Digital Live is just faking it. Im thinking that during gameplay, DMC just isn't as robust in the audio department, and the cut scenes are rendered with 5.1 in mind. Hopefully this makes sense, and if anyone could help that would be great.
