Dw8000 voice 8 issue

I have a dw8k that is having issues with voice 8. When the board is in poly 1 mode the 8th voice is dead. I went through the voice board and replaced all the logic chips and op amps in the signal path thinking one of the chips was stuck in the closed position with no success. All the ic are meaturing correct voltages on the voice board and so now I'm looking at the the CPU board. could this be some bad ram bits? Any help would be super appreciated!

I did look at this post before posting but I missed that link to a blog with even more details. Looks like I'll need to scope those chips and see if where it's getting stuck.
