I'm looking for a primer of sorts on how the audio channels work on a DVD/CD drive, and how they get into my PC. I just installed an EMPREX DVD Dual 8x Internal DVD+/-R and +/-RW drive. The CD drive I replaced did not have the 4-pin audio cable on the back yet I could hear music OK through the system sound. I suppose it came through the IDE cable. The sound from the new drive is very faint using only the IDE cable. I tried jumpering the 4-pin caudio cable to my sound card "input" and get nothing. Apparently, I don't know how sound is generated by DVD/CD drives and how to get it into my PC sound system. Yes, I checked the WindowsXP sound display of inputs; none are muted and volumn controls are all at 100%. Yes, the sound on the DVD player display is not muted and is likewise set to 100%.

In your dissertation explain (1) the audio route via IDE cables, and (2) audio route via sound output on the back of the DVD drive. When do you use what? Am I in the midst of analog vs. Digital outputs? I will appreciate getting educated!
