No sound after sleep

Same problem here with my Late-2013 rMBP 15". It's annoying that I need to restart the computer to get the sound back. Need a fix!

I have the problem, did the update and still no sound.

I think that the problem is in Adobe Flash player.

Having the same issue for months...

You can fix it without restarting by doing this :

sudo kextunload /System/Library/Extensions/AppleHDA.kext

sudo kextload /System/Library/Extensions/AppleHDA.kext

sudo killall coreaudiod

But this will just restore the sound until the next time it crashs...

Apple ?

Ok so I tried to run these commands the last time the sound died on my Macbook Pro. I first closed all the apps that were using sound: Chrome, iTunes, etc. However when I ran the first command I got back a message that the kext could not be unloaded because it was being used by two processes. Without knowing what these processes were, I was stuck. I looked to see if I had other apps running in the background that might be using sound but I couldn't find anything. I quit a few apps that were running in the top bar too but no luck... same message from Terminal when I reissued the command.

Any thoughts on how to determine which apps are preventing the kext from unloading? I'd love to have a way to restore my sound when it goes away without rebooting but since this method isn't without issues, I'm not sure what else I can do but reboot.

Even i am facing the same prob with my MBPr 2014. And it is really very annoying.

A heads up for everyone. OSX 10.9.2 is on the App Store. Keeping my fingers crossed.

Hey! The Dr. Prem post on Page 2 actually fixed my problem. Thanks!!

1) Open finder and click Go on the top of the menu and click on Go to folder then Enter " /Library/Preferences/Audio"

2) You will see two files, drag those two files to desktop (you may need these backup files)

3) Restart your mac in safe mode...

- Restart and hold shift key when you hear tone and before the gray screen appears.

- Release the key when you see spinning wheel and logon to your account.

4) Repeat step 1) Now you shouldn't see those two files there. If you see those two files, select both files and move to trash.

5) Restart your mac, make sure those two files are not in the folder.

First test on 10.9.2 seems to have resolved the problem... not chanting Victory yet, but it seems to work.

10.9.2 does fix the bug . Atleast untill nw it seems to be ok.

10.9.2 in MacBook Pro 15' Retina late 2013, sound keeps dying after sleep. Sad thing.

10.9.2 seems to fix it. Well at least it did when I extensively tested the rMPB!

I posted about the "heads up" on 2/25. No problemos after update and many "sleeps". I hope this is the end of this mess for all.

I have the same problem. No sound after sleep.

:-(

I need to restart my Macbook Retina 15" late 2013.

Even with 10.9.2 nothing changes.

I once talked to Appe Support. They had no information about this issue. Only stadard procedures.

But look at the long list of this thread. There must be somthing wrong.

Apple, wake up! Become aware of it!

This one worked for me. I also got errors that some apps were using the driver and the solution was to quit Skype.

I even made a small script I can run whenever this happens again:

#!/bin/sh
echo "Make sure to quite all sound using applications before running this (i.e. browsers, skype, garageband, etc.)"
sudo kextunload /System/Library/Extensions/AppleHDA.kext
sudo kextload /System/Library/Extensions/AppleHDA.kext
sudo killall coreaudiod
echo "Done, try changing the volume up and down a bit."

Put the text in a file and make it runnable by running

chmod +x filename

Hope this helps!
