Windows 10: Extremely high sound latency issues

I'm having major sound latency issues, and I think I have isolated it to my SSD, I'm just not sure how to fix it at this point.


I have run LatencyMod and this is the report I get. Right now, storahci.sys seems to be the main culprit:

The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution.

Extremely High Latency

Hello,

Recently I have had major issues with stuttering during normal computer usage, especially when browsing the internet or downloading content. As part of troubleshooting and ran latency monitor and discovered that my interrupt to process latency was exceeding
10,000,000 us. This latency issue continues for as long as there is internet traffic. I do not have a wireless connection (wired directly to DSL modem). What is interesting is that gaming is
not affected. I do not play multiplayer games, but all the single player games I play run perfectly smooth, including newer titles like Rise of the Tomb Raider, DOOM, Frostpunk, and Mass Effect Andromeda (all at max settings). Many game titles
I even run at 3x DSR without any hiccups. However, when not gaming and just using the internet for tasks my computer is rendered almost unusable, especially during major downloads.

What I have tried:

• Checked for viruses using malwarebytes
• Updated video drivers
• Updated sound card drivers
• updated NIC drivers
• Updated USB Drivers
• Disabled CPU throttling features via BIOS (C-states, cool n quiet, C1E, etc)
  
• Tried enabling HPC and Core Performance Boost in BIOS
• Tried disabling ZoneAlarm firewall and virus scanning
• Tried disabling NVidia audio devices (via graphics card, also tried removing their audio drivers)
• Used CCleaner to cleanup files and registry

None of the above worked. Usually my highest reported ISR is dxgkrnl.sys and highest DPC is ndis.sys. However, sometimes the highest ISR shows up as HAL (Hardware Abstraction Layer). The DirectX graphics component points to the video card (GeForce 1070)
but if I had issues with that I would expect to also have issues with gaming, which I do not.

Any suggestions for what to try next would be greatly appreciated.

System Specs:

• Windows 7 64-bit
• 24 GB Ram
• AMD FX-8320
• GeForce GTX 1070
• Soundblaster Zx Sound Card
• Two 7200 rpm HDD's (Seagate 1TB, WD Black 2 TB) OS on seagate

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 that belong to a driver running in your system appear to be executing
for too long. Also one or more ISR routines that belong to 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.

REPORTED HARD PAGEFAULTS

_________________________________________________________________________________________________________

Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted
and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: system

Total number of hard pagefaults 6992

Hard pagefault count of hardest hit process: 3254

Number of processes hit: 19

High Latency

I'm having an issue with high latency. After a reboot the computer runs fine....but over time the latency continues to increase so eventually everything starts to respond so slow that it is unusable and have to do a hard restart. I haven't been able to
figure it out. I bought an external network card to use instead of the onboard one hoping that would fix it....but same results. Anyone have any ideas??

 

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.
