However, I see more processes running on cpu3. Processes called 'migration', 'kworker' and 'ksoftirqd'.
Is that expected behavior?

Lower clock speed --> less power use --> less CPU noise --> better sound
Better aligned clock speeds --> less random & periodic jitter --> better sound
Less power use --> less strain on power supply --> less noise & jitter (cuz it's like that) --> better sound
I've made some of the mods in this thread including underclocking as he suggests with my settings now being:
- Code: Select all
# HDMI disable
The initial_turbo=60 gives you 60 seconds of turbo mode when you boot up.
This article https://haydenjames.io/raspberry-pi-2-overclock/ gives some useful background.
The system runs perfectly with these lower settings. Not sure I can hear a significant difference but perhaps my ears can no longer detect real subtleties. Listening comparisons are notoriously difficult anyway, with minute differences in volume giving an apparent improvement.

Yes, all changes, step by step. The last was the soxr thing.
I always listen to full albums and most, or lots, are continuous, so it's really nasty to hear the gap each time with a loud pop.
The GPIO thing I may try. Is that (part of) the fboe mod?
Thing is, I'm not a soldering expert.
