Hi!!! This is a fix for Vista, If your using another type OS the solution is a little different. You'll have to check to see if you're up to date on the latest version of Yahoo Messenger- either 8.1.0.421 or the 9.0.0.922 Beta for this solution to work. This site that I'm giving you, can update you and install the codec necessary for Vista. Cant participate in yahoo messenger conferece,error :audio compression is not supported by the computer? - Yahoo! Answers Sincerely, Celestra
