    Flash Player 11.3 Audio Update

    chrisc59802590 Adobe Employee

      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.


      No audio in some of the speakers in a surround sound system on Vista or Windows 7

      7. Click on apply and OK.
      8. Go to IE/Firefox and play any Flash movie.
      9. Let us know what the result is.
      10. Also, play around with the Default format combo box in Speaker properties and let us know what works and what doesn’t.
