Briefly -
There are three ways a CD can produce sound: 1 An analog cable from the CD to the sound card. 2 A digital cable from the CD to the sound card. 3 A digital signal processed by the PC and send through the PCI bus to the sound card - which I assume is your case. |

That is Digital Audio Extraction (or as MS calls it, Digital CD Audio) where the data thro your IDE cable instead of an audio cable.
It goes to Ram and then the CPU converts this to a stereo music format that is then sent down the PCI bus to the soundcard, where the soundcard plays it like a wav file. Not all older CD-Rom drives support it and as can be CPU/PCI intensive, many people still use an audio cable for analogue or digital audio. Many consider digital audio to be the best. HTH |
