CDX sound missing effects generated on genesis only can hear 8bit like sounds

[acem77]

I only hear some very basic 8bit like sounds... almost like a sega master system.

This is odd seems like a bad cap somewhere.
99% are surface mount..........

If I finger caps near the sega 315-5684 I can start to hear the missing sounds tones.

I cant find the yamaha YM2612 5 or Texas Instruments SN76489 chips on the cdx mother boards??


Found this problem when my model 1 sega cd was giving me skipping issues with pier solar audio cd.

So I fired up my cdx, and only head the enhanced audio on the cd and none of the cart generated sounds.
If I start pier solar with just the cart I hear some music but most of the notes and tones are missing..

Same thing with every other game I try.

Anyone have a dirt cheap cdx with a bad cd-rom to sell?
