Windows 10: Audio cracking and high dpc latency

I have been struggling to solve an issue with audio cracking and popping on my pc. Using latency mon it is showing that ndis.sys is the highest dpc routine and that dxgkrnl.sys is the highest isr routine but sometimes when I'm having the audio issues latency mon doesn't report any high latency. I've tried updating my network adapter driver and graphics drivers to no avail. I've also update my bios to the latest version and still no luck. It is driving me crazy trying to fix this issue since I haven't had any problems with my pc up until earlier this year when this started. PC specswindows 10 h

High DPC latency

I use my Dell XPS for recording and live playback but the system suffers from high DPC latency caused by ACPI driver.

I removed Dell audio drivers and installed those from RealTek with no avail. Latency is an issue because I need this computer for live recording. Please your advice.

 

Windows 10: High DPC latency (ndis.sys)

Recently, my audio has been crackling and popping and glitching, and I wanted to see what the fuss was all about. I tried everything. Until I found out that my DPC latency was dangerously high. I ran it through the DPC Latency Checker and LatencyMon, and
apparently the problem was "ndis.sys". I've literally tried EVERYTHING. Here's a list of what I've done to resolve this problem:

• Updating drivers
• Changing the power plan
• Disabling the dynamic ticking
• Updating the graphics cards drivers
• Disabling Firewall
• Disabling IPv6
• Uninstalling Bonjour
• Disabling Energy Efficient Ethernet
• Disabling/re-enabling drivers
• Adding PerfLevelSrc, PowerMizerEnable, PowermizerLevel, and PowermizerLevelAC values to Registry Editor
• Uninstalling antivirus software
• Modifying the "Start" value in the Registry Editor's value to 4

UPDATE: Recently, the DPC latency has declined, which is good, however it still sometimes has latency-spikes and I still don't have proper DPC latency.

Audio stuttering/buzzing and storport.sys high dpc latency

I've only had this audio issue for a few weeks already after I did a custom windows 10 install bc of a previous problem. I've also posted twice about this but no one has helped me yet. I'll post the following possible solutions and suggestions that
I've already done to avoid repeated answers

I did: audio troubleshooter, uninstalled then reinstalled audio drivers, disabled audio enhancements and tried different audio quality under the advanced tab.


After more searching online I tried using DPC Latency Checker (and then LatencyMon to be more detailed) since I read that having high dpc latency can cause problems with real time audio among other things. Apparently
storport.sys is the problem? I literally just have basic knowledge about anything regarding this kind of stuff and I don't have any clue on how to fix this so I just hope someone can help me and give me steps by steps suggestions on how I can solve this. my
audio has just been driving me crazy with those stuttering sounds and I don't want it to worsen.

I would also like to know if having
Ricoh SD/MMC Host Controller and nothing else aside from that, under
IDE ATA/ATAPI controllers, is okay and won't cause problems?

please, I hope someone can help and answer this time around!
