In the last week became harder to observe problems with sound in games, videos and music. I use external sound card M-audio Fast Track USB.
Conducted analyses, tests, and found that for some reason the antivirus creates a really wild delay his driver (see screenshot). I have ESS NOD 32 version 8, before that was 9, and the same is wildest stall and it is not clear why this is so.
I understand that you say "Change your antivirus to another...", but maybe it's a side issue, because recently all was well and no problems.
Without antivirus everything works better.
Tell me what to do, where to dig further?
