You can't use the drive's analog/digital audio outputs with DVDs; those only operate for CDs.
Your best bet for extracting audio from a DVD is to rip the DVD using a tool like DVD Decrypter. You can then use MPEG tools to demux the audio stream out of a VOB-style video into a separate file, and use GoldWave on that.
Updated: Here's how to use DVD Decrypter to rip just the audio stream you want from a video DVD. I don't know if this process will work with a DVD-A, but it's likely similar. (Credit to Software Monkey for the steps.)
In the Mode menu, set Mode IFO.
The main window will get a Stream Processing tab. On it, select "Enable Stream Processing". In the window, leave a check by any stream you want; clear the checkboxes beside any stream you don't want. DVD audio streams are formatted as AC3, DTS or (L)PCM.
Select the stream you want, and select the "Demux" radio box at the bottom.
Check the stream processing options in the program settings (Tools -> Settings). If you're getting PCM data you probably want to check the "Convert PCM to WAV" box. (This is checked by default.)
Set the output destination, and click the "Disk-to-Drive" icon to start the process.
Now you can import your ripped audio into whatever audio processor you like. Enjoy!
Original: I noticed a label on the bottom of my recent internal DVD drive purchase that says:
No Audio and Digital out function
even the pin-set is on the connector
It's unclear, but I interpret this to mean the audio output pins that would connect the drive to the soundcard are non-functional.
This means ripping the CDDA audio off the CD is the only way to import the audio. (Which is OK, since you get better results this way than recording the analog playback.)
OOPS. You're talking about DVD audio. That's different; that gets pulled off the DVD as a digital file anyway. It never went through the CD-in on the soundcard. That sound is generated by whatever player software you're using as it decodes the MPEG-2 streams on the DVD.
sounds good. updated with your process. – quack quixote – 2010-01-21T04:11:20.913
1the audio connector between the drive and soundcard is a vestigial thing from back when CD drives had the circuitry to play audio CDs by themselves. DVD drives have, to my knowledge, never had equivalent functionality for DVDs. – quack quixote – 2010-01-20T02:58:17.147
Trying DVD Decrypter now. – Lawrence Dol – 2010-01-20T03:01:55.187
Man, my edit was too slow! – Jared Harley – 2010-01-20T03:02:41.380
@Quack - Good to know about the audio connector; so I can just remove that cable and never bother with it again, then? – Lawrence Dol – 2010-01-20T03:03:55.540
What MPEG tool should I use to demux the audio out? – Lawrence Dol – 2010-01-20T03:04:22.250
TMPGenc, VirtualDub, ... GoldWave might do it directly according to a post here: http://forum.doom9.org/archive/index.php/t-21883.html ... and this says you can do it with DVD Decrypter (stream processing options): http://forum.doom9.org/archive/index.php/t-80441.html

I did it with DVDDecrypter, but how to do it wasn't so obvious. Could you please add to your answer: "Using DVDDecrypter, set Mode IFO, and then select stream processing, and then ensure only LPCM option is checked to get the 2 channel stereo track. To output as wave, the corresponding Stream Processing option in Settings must be checked (on be default)". Then I will accept it. – Lawrence Dol – 2010-01-20T21:14:43.257
