I'm having huge sound issues when playing two specific games on my PC: Bioshock: Infinite and Civilization 5. The sound will start cracking and dropping out after a while of playing. In Bioshock this will normally start to happen after about 5 minutes into the game, in CIV it will take an hour of playing and will only appear when I start to zoom out very far from the map. The graphics are not affected though, they will continue running smoothly.
So I ran LatencyMon to see if there were some Latency issues. And the first thing that caught my attention was the USB 3.0 drivers having a very high "highest execution time" - it was about 17.5ms. After some googling I figured could be because I plugged my external audio interface (a Komplete Audio 6) into one of the two USB 3.0 slots my PC has, as appearently the USB 3.0 drivers seem to cause many issues on Win7 systems. So I deactivated the drivers in my device manager and plugged the interface into an USB 2.0 slot.
After retrying to play Bioshock, the same cracking issues started to appear, but slightly less. This time, my LatencyMon showed the USB 2.0 drivers having huge execution times. After a while of further playing, the latencies for dxgkrnl.sys and afd.sys went up too (screen attached).
Also, the driver console of my audio interface will show several "USB I/O Errors" after the cracking appeared.
When I play the game on my TV, sending the audio through HDMI to my AV-receiver, I'm having no issues at all.
I updated my graphics card drivers and the audio interface drivers and turned of power saving for all USB slots, but still no change.
Do you have any idea what else I could try?
Here are my specs:
Win7 x86 SP1
NVidia Geforce 760
Komplete Audio 6
