Update 7/11/12 - We released Flash Player 11.3.300.265 today to address most of the audio issues that users have been encountering. If you continue to run into sound issues, please try adjusting your sound format using the instructions below.
Update 6/28/12 - Please see "Flash Player 11.3 Status Update" for the latest information on our next Flash Player 11.3 release. It includes details on the expected time frame and fixes that will be included.
In Flash Player 11.3 we added new, low latency audio support to allow Flash developers to improve their application and game audio performance. It appears that under certain configurations this can cause issues that we did not encounter during our internal testing or in the two month public beta program for 11.3.
I will continue to update this post with additional information when available.
