Stephen, 

I don't have a "noise" problem per se.  It's more of a muted voice 
problem.  Nothing at all plays on channel 7. You have to listen in 
very, very close and instead of the sound you'll hear an VERY 
soft "krkrk" sound, but it's almost inaudible.

Do you still think replacing the ceramic caps will make a difference? 
Are they hard to replace?

ceramic caps associated with channel 7 if it still giving noise 
issues, as the chip is obviously fine if you swap and the sound does 
not follow. It is surely component a problem on that particular 
channel from the sounds of it.
