Audio AudioClips are delayed

First of all, this is not related to the iOS or Android games lag.

I am pretty new to Unity and I made a game all through ignoring the fact that in game audioClips were delayed (picking items, receiving damage), all of my clips are in WAV se they would have no problems decompressing and still I get that annoying delay when the clip is supposed to play.

I don't see many threats on this regard so maybe I'm missing something in the settings...

please help
