I've
- disabled the onboard sound on my motherboard via BIOS,
-made sure my threads don't "park", (high perf mode)
- made sure my USB's don't go to sleep,
-have my media files on a separate fast SSD drive,
-made sure my startup menu was clean and prevented a lot of background apps from starting at startup
but none of that has stopped my fairly high performance windows 10 pc from clicking and popping while playing back audio where there aren't that many tracks playing or FX engaged.
The ONLY thing that stops it is forcing Cakewalk or Sonar to load with "Real-Time" app priority (which you can see in Task Manager). So, I know there is SOMETHING that seems to be competing for resources but I'm not sure what it is. Any clues or suggestions from other users who have encountered the same?
Also... LatencyMon says my system is fine and suitable for realtime audio playback.
