Taking a while (days) before it happens suggests some program or device is not clearing memory or unloading when its not in use.
I don't keep mine powered on overnight so I never get to that point, to see what mine would do. I use my system for my recording studio so I keep an eye on everything, but powering off over night and powering on in the morning there is nothing there.
One thing I see, I see RealTek and I also see Creative (soundblaster). Do you have both a Soundblaster sound card and Realtek or is the Soundblaster just the software enhancement? If you have both an actual soundblaster sound card and realtek, the realtek should be disabled in the BIOS or there will be conflicts and potential sound problems. My recording studio system (what is in My system Specs) motherboard came with the SoundBlaster enhancement. I initially installed it but later uninstalled it as I never used it. If I want "high quality" sound, I just use my recording studio hardware with the PC.
I ran into another (USB) problem with a Logitech/mouse combo that use the Logitech "Unifying" system (bluetooth connections) and had to go back to a wired keyboard and a "standard" wireless mouse. That mostly affected the keyboard but I was having some other flakey problems.
Finally, are you using a wired internet connection or a wi-fi? Wi-fi is a known cause (there are others) of the stuttering, popping crackling of sound.
