I would sugegst getting a higher quality source for your audio.
I amnot sure what you are describing, you mean drop outs, like the audio stops?
What you are describing is technically not jitter.
I've tried with both onboard and my USB DAC (iBasso D2 Boa). I guess what happened are drop outs, like the music stutters for a split second. In the worst case, my music just stops.

I'm using MediaMonkey. Sorry for the misuse of the term "jitter", still a newbie here :P
I've tried that, didn't seem to help. I have 4GB of ram, and I have more than 50% free most of the time, so I don't think it might be the issue.

Desktop hardware and the drivers may not expect it and may not handle it properly.
So look for the most current drivers for anything and everything, but especially things on the mother board.
I'd put a guess on a driver that doesn't initialize properly after waking from sleep mode and is stuck in a CPU hogging state. That is something that will cause high DPC Latency delays which will cause brief audio dropouts.
Read up on DPC Latency. Run the DPC Latency Checker. See what it does in normal use. See what it does after waking from sleep mode. Read the info on the DPC Latency Checker web page for background info on what's going on. Read the Product Sheet PDF file as well. It will explain things and give some guidance in how to figure out what device is causing high DPC Latency.
I ran the DPC Latency Checker, and it is showing yellow bar + rather frequent red bars. I think this is the issue here. (I have left my computer on (including sleep) for a few days right now) I will retest when I shut down and turn it back on. I've tried disabling my network and sound drivers but to no avail. I will read up more on DPC Latency and see if it can solve the problem.
Update: I've turned off and reboot my computer, latency is still >1000us. This is abnormal right? I've uninstalled Microsoft Security Essential and got Avast instead, because I read online that MSE causes some DPC latency issue.
THANKS A LOT for all your input so far!
