So I got an issue with the sound coming out from my laptop, after a while the sound will become distorted with cracks and pops and it get way worse after a while, this is not a problem of sound card, since I tried with 2 soundcards and they both have the same problem. accordin to several info I got , it seems that I have what is called a DPC latency problem , so i checked it with latencymon, this is what I got

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines executed by a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:19:37 (h:mm:ss) on all processors in the system.

can anyone help me with this?
edit:
the problem seems to lie with high kernel latency

I'm not sure about DPC latency, I don't know much about that. But I had the same problem recently while playing music + playing minecraft + hosting a server. Turns out it was just because my processor couldn't handle it all at once (though the music was the only symptom). Try closing everything else and testing some sound then (while keeping an eye on your processor usage).

i kinda did, and the same problem appeared again, I am running an intel i7 on 2.70 ghz there is a huge problem if it can't run one game (TERA online) or even low requirement games such as SDGO without doing anything else
