Hi, I have pretty much the same problem here, just bought a 192 unit of ebay with 8 a/d and 8 d/s and digital in/out, have test all the a/d and get crackling (like statics noise) on channel 1 and 2, the other 6 are perfect, i will try to dismantle the whole thing and give it a clean up, perhaps that will do the trick and i will let you know what i found. I will also try to card on slot 4 which is the slot below the digital in/out slot, right?
