Audio cracking during video playback - DPC latency problem?

This has been happening for a long time, but it's really starting to drive me insane now.
I noticed it happens more often the longer the computer has been on for. It happens whether I'm playing a downloaded video or streaming something through a browser. I suddenly hear the audio make a crack sound.. sometimes it can go about a minute without making it, but more often it happens every 10-20 seconds.
Through googling I think it's called a DPC latency problem?

Through my google searches I saw people were trying to figure out the problem through a program called LatencyMon, so I downloaded it and ran that and Latency Checker.
I have tried many things to try to fix this including update my BIOS, update my sound drivers, disable various items in device managers and monitor the latency, disabled CPU throttling..
I just can't seem to fix this!

I've included my dxdiag and what LatencyMon looks like after having it run for 20 minutes.

Thank you so much for any help!

I'm not sure if this is useful information, but I mostly use my computer to watch downloaded videos via HDMI to my TV with a soundbar. This cracking sound happens on both my soundbar and my computer speakers, so I know it's an issue within the actual computer rather than it being a speaker problem.

EDIT: I just saw the other thread which talked about what information to give. I just ran the command to get the trace file. I hope I did this correctly.. here is the link to my trace file.

Sorry for the double post, but I can't seem to edit my first post for some reason.

I just found something really interesting.
My mom and dad both have computers as well, so I decided out of curiosity to run LatencyMon on their computers to see if they might have the same problem. LatencyMon said both of their computers also have real time audio/video problems.
Attached is the screenshots of their LatencyMon results.
