Hi guys, I have spent the last week reading and trying to track down this issue. I have sound stuttering and popping due to dpc latency when gaming. I have read a bunch of threads on here, so I went ahead and pulled the trace information that is usually requested. I have been using Latency Mon and it shows nvidia drivers having the issue, but I think this is a false positive based on what I have read and something else is causing a conflict with the drivers. When the system is idle Nvidia stuff hits around .6ms alone, when gaming its in the 2.5ms range (using latency mon). I am using HDMI out on the gpu to send out sound.
Things I have tried:
Newest MB Bios
All newest drivers from MB site
Refresh of Windows 10
Driver Verifier flags are off
Multiple Nvidia Drivers
Disabled PCIE power saving in windows and nvidia
Removing/changing slots of SBZ
Turn off speed throttling tech on CPU
Turn off Hyperthreading on CPU
uninstalled all software that isn't required (including Gigabyte software)
updated Intel Drivers from the Motherboard site
disabled the intel i219-v ethernet controller
rearranged SATA HDDs
unplugged SATA DVD Drive
Moved the GPUs from IRQ to MSI
disabling unused hardware
onboard audio and vga are disabled
only m+kb plugged in
disable HPET in bios
Stock and XMP Profile Memory
installing new intel drivers 10.1.1.13
dropping to gen2 pcie
Dropping PCIE to gen2 does help with stopping the sound stuttering but I can still see latency going around 1.2ms.
I have attached my cpu and kernel output from the trace when running 3dmark to imitate gaming environment. Any help would be much appreciated!!!
