A portion of users recently reflected that the new 2013 MacBook Pro That Apple released during the September event, with MacBook Air 2013 Launched earlier this year, encountered an audio error when resuming from sleep mode. . The MacBook Pro 2013 was released by Apple at the September 23 event with Haswell, Retina display and running OS X Mavericks operating system.

According to users, their MacBook encountered a loss of sound after turning on the device from sleep mode, and they could not activate the sound on the device. In addition, users also said that when observing in the task manager on the operating system, they found there was a strange process that consumed CPU, and this process also appeared when the machine turned on from sleep mode. In system log, users see errors such as:

10/28/13 03: 46: 27, 000 kernel [0]: Sound assertion in AppleHDAController at line 5460

These errors seem to only affect MacBooks using Haswell chips, ie both the MacBook Pro 2013 and the MacBook Air 2013. And now there seems to be no way to thoroughly fix the error. On the Apple forum some members have tried some solutions such as restarting the computer, however, it is not always the first reboot to fix the error successfully, so you may have to restart few times to fix.

Currently Apple has not given any feedback on this error. Previously, the 2013 MacBook Pro also suffered a number of errors such as a keyboard and trackpad hangs. Apple has confirmed this error and promised to fix it in the near future.
