My sound is bugging just when I click on Play after picking phase (sounds like when you are on skype and your internet connection is lagging) and when the loot comes. The game has some micro freeze also during this bug (visible only during picking phase sound bug, not sure on loot phase).
It is really annoying and I always drop down my micro-cask (?) when it comes to loot sound bug.

DotA 2 is my only game where a bug sound occurs. I dont have tried to reinstall it.

Any feedback like this one ?

(Sorry if my english is bad :])
