Does the problem happen with authentic Game Paks? Can you name some games where you notice missing drums, etc.?
Problem started when i used PowerPak. I launch NTRQ tracker and nothing plays on DPCM channel, only clicks there. Yes, it is on other Game Paks too (for example, dog is not barking in "Duck Hunt" on original "Super Mario Bros./Duck Hunt" Game Pak).
Did you modify the audio circuits on the NES at all? i.e. a stereo mod, or "Resistor mod" for the powerpak?
It's possible that if you did one of the above that the noise/triangle/DPCM channels aren't working. If the audio stuff wasn't touched and JUST DPCM is out (listen for the noise channel on i.e. SMB... it shares the same output pin as DPCM) then it truly did fail, and you need a new CPU.
I doubt the powerpak did it, and it was just a coincidence, since the PP doesn't connect to the audio lines in any fashion.
