Some new MacBooks refuse to play sounds after restarting from OS X Mavericks Sleep Mode

  OS X Mavericks turns into a nightmare for those who have had the courage to install the latest version of the operating system for Macs, a new bug giving headaches to users all over the world. It seems that when restarting a MacBook that entered sleep mode, OS X Mavericks automatically block the playback of sounds only in MacBook Air/MacBook Pro Retina Display 2013. Extremely many users encountered the problem after using the sleep mode in Mavericks, and apart from closing the sounds without the possibility to reopen them, OS X a process is also running which consumes a good part of the processor resources.

  Unfortunately, there are no methods that solve the problem all the time, but some users have been successful in reactivating sound in OS X Mavericks by connecting a set of headphones or performing a restart. Unfortunately, the problem is not always solved on the first try and Apple does not seem to have a solution for it yet, but probably next week it will release an update for its products, it remains to be seen how long it will take until it produces it.
