Hi! I've got some problem with voices in some games. When launching game there show that warning: "There will be no voice or sound effects because the system does not support ADPCM files. Do you wish to continue? (CODE = 0:0)" It's iritaiting me, so I'm asking for help. I have Windows 7. Problem is only with voices, sounds are in games. Sorry if it was at page, but I Was unable to find it. Please help.
