At least I'm pretty sure.
I'm at the limit of my technical knowledge unfortunately. I just built a rig last month and it ran fine until this week.
MSI GTX 1080 FE
I7-7700k
Asus maximus IX formula
Windows 10
When any system tones come over the speakers that come from the Displayport audio they sound like garbled windows 97 era game explosions. Trying to play rocket league over the speakers has the title song with only a garbled, modulated, and friggin creepy voice track and the music background is seemingly gone. The audio works just fine using headphones plugged into the motherboard jack.
I was using LatencyMon and found that dxgkrnl.sys has the "highest reported ISR routine execution time" and nvlddmkm.sys has the "highest reported DPC routine execution time"
what either of those mean, i havent a clue, but seems to be the issue.
system wide responsiveness is crap, and games will at the LEAST microstutter like crazy every second or third launch, otherwise it will run horrifically at 20 ish FPS when im used to getting stable 144 fps.
All of these issues completely vanish when i disable the GTX 1080 through windows. (Advanced display settings > Display adapter properties > Properties > Driver > Disable) audio over the speakers works perfectly, system is responsive
I've rolled back the Nvidia drivers to a few previous versions (clean installations) and the issue persists seemingly with each driver.
I THINK ive found the root cause but don't know how to fix it. I might be barking up the wrong tree altogether though, thanks in advance!
