I didn't get either with the drive(used auction drive), but I ordered them from game doctor hk.  It was about 8 bucks.

Thanks for the info.  This now makes more sense to me. 
Also, I'm not using two power adapters.  I have a cable that strings the power from the SCD to the SGX.

Hey Guys,
First time poster, so please let me know if I'm doing anything wrong.  I've searched on this topic a few times and gotten related hits, but nothing specifically like mine.
I've got a modded Supergrafx (modded with a region switch and a scart rgb out) from a ebay seller doujindance.
I bought an additional Super cd-rom2 to mount onto it.  The super cd-rom2 unit has bad caps.  I haven't opened it, but I knew this because the original seller said audio out didn't work, and that symptom matches a number of these units having bad caps (similar to duos).
I expected to have to get this repaired upon receiving the cd-rom2.  Before sending it out for repair, I hooked up the drive and tested it to make sure everything else was okay.  I played several games (Dracula X, Y's 1 and 2, Y's IV and Valis 2).  As long as I hook the audio to the Supergrafx out, and don't plug anything into the Super cd-rom2 out, I get cd sound through the Supergrafx.
This brings up 2 questions:
1) Has anyone else seen similar behavior?  My earlier searches were here before buying the Super cd-rom2 (as a forum lurker).  Based on what I read then, this shouldn't be working this way.  I should only be getting sound effects and digitized sound.  I do remember seeing a guide previously that stated that the cd audio was handed back to the console over a few pins, but the console didn't use it.  So I guess it is possible the original modder (doujindance) hooked that to the av-out while doing the RGB mod.
2) Is there any reason to get the bad caps in the super cd-rom2 fixed, other than selling it?
If this is a result of a mod, it seems like it would be smarter to do something similar, rather than hacking up a ~$200 Super cd-rom2 if you had the same problem (not that replacing caps is hard for a experienced solderer).  I know I have a Supergrafx, which isn't cheap, but if you didn't want that compatibility, cores and pc engine small units are really inexpensive, and not a lot lost if you mess up the mod bigtime.
