I have recently installed the mac version of dota 2 (was previously using the windows version via playonmac). The sound works fine in the menus, but when I get into a game there is no sound. After about a minute game music and sounds from abilities start working, but I still have no sound from heroes or anoouncers. Also my hotkeys don't seem to be working. I have checked, they are assigned to the correct keys, it just does nothing when I press them. Any ideas?
