I just got a 32X today, but to add to the fun, I only have a Genesis 3 and X'eye -- I don't have either of the basic Genesis models. To add to that, I don't have a stereo A/V cable for the 32X, since it just comes with a mono cable (wtf, Sega?). I got around this by hooking the video line from the 32X to the TV, and using the standard stereo output from the X'eye for the sound.

My question is, will I miss any 32X audio by doing this? It works great with Genesis games, but I'm not sure if there's any audio that the 32X adds that doesn't get passed back through the base unit's audio out. I don't have any 32X games yet to compare with (and on top of that, I think there are differences between games on whether they use the 32X's audio hardware anyway, right?)
