This problem only occurs while in game, AH2.  I'm setup with a 5.1 speaker system.  No hissing while playing music.  This never occurred before upgrading to Windows 10.  I did upgrade the drivers as suggested in a previous post.  This afternoon, I played for nearly and hour before the "slow motion, garbled" sound started.  The only way to get rid of it is to log out and restart the computer.  Thanks for the help gents!
