Crackly internal sound, some USB devices not working properly
First of all, I caonsider myself a power user. Which means lot of installed programs, apps, utilities etc...
WinVer: 1909 (18363.1139) Professional X64
It looks like something in my Win10 install in taking too long time in ISRs which causes some HW devices to "stutter" for example occasional cracks in audio, or stuttery output from USB RTL-SDR.
When running on clean install, everything runs smoothly. Then I install programs as I need them, and I can never notice when, but always after about 6 months from clean install, I notice occasional crackles in my internal soundcard's output. Doesn't matter if playing on internal speakers or via AUX outptut. Also related issue might be that I experience gradual shift (desync) in sound while watching videos, (sound falls behind video) no matter videos on youtube or in VLC from local drive.
For some time, I "solved" this problem by using cheap USB soundcard, which, compared to the "crackly" internal soundcard, was playing buttery smoothly. But my USB soundcard broke for - to me - unknown reason, and so I am forced to use my internal soundcard reminding me of my system's long ISRs once again. On the top of that, I decided to play a bit with RTL-SDR dongle, and the sound as well as the displayed waveform are... eh, choppy, or stuterry I would say, I just think it's for the same reason as why my soundcard is crackling.
I tried running latecymon, and statistics for my system are pretty bad - unusable I would say... Screenshots here: Imgur: The magic of the Internet
But, when I run latencymon on the clean install of windows, I get good values, not excellent, but good enough for sound not to stutter, and RTL-SDR to run smoothly as well.
So, I am asking you, oh great people of tenfoums, what I am doing wrong, to deserve such hell-like latency? (Btw I already disabled that... battery ACPI device or whatever, yeah it did help a bit, and... we are staying in that "bit" part. it's like 10% improvement...
