Thx Zorlacc, but it did not provide any solution for me.
Did what you wrote and got no errors 2 times, rebooting between each time.
C:\Windows\system32>sfc /scannow
Beginning system scan. This process will take some time.
Beginning verification phase of system scan.
Verification 100% complete.
Windows Resource Protection did not find any integrity violations.
C:\Windows\system32>
Still same problem im afraid.
2 soundcards + 1 usb headset - Same sound **bleep**
Checked my dcplatency and its around 70-100, never seen it above 120 (which should be great..)
Am now running with x-fi soundcard and stereo headphones. Tried every setting possible ingame (home cinema - war tapes + stereo/surround) + tried a bunch of "tweaks" posted around the net.. absolutely 0 improvement.
Reinstalled bf4 and made sure to delete the "documents -> battlefield4" folder to reset all settings.
Read loads of suggestion on the net, also on the "tweaks", where its apparent that noone really knows what the different settings do :P
No other game i play have ANY sound problems, its only bf4 ☹️

PS. I do mostly play TDM maps, and i know it was a lot of problems with sound + TDM maps in the january update, but this "should" have been fixed months ago..
