No sound out after wake up in Mavericks

Proggie, that sounds excellent. Way more than Apple has done. 😟

If you share it, we'll be able to verify the contents of the script.

OK...try this and let me know if it works: https://dl.dropboxusercontent.com/u/98285/RestartAudio.app.zip

Had to zip it up or it wouldn't work when downloaded. So unzip first (should be able to just double-click), and then move the file to your Applications folder. The first time you launch it, you may get a message that it's from an unidentified developer or something like that. In that case right-click on the application and choose open, then click on the Open button. Then type in your admin password.

Thanks Proggie, your solution worked for me!
Finally some way to fix this issue, at one point I completely broke my audio drivers trying to fix this.

Thanks, for your suggestion with deleting the sound device files, worked great for me.

10.9.2 / Macbook Pro 15" / Late 2008

Proggie's app works... thanks a lot ya legend. Get a job at apple!

Another +1

works for a while after a reboot, then stops and requires another reboot.

Actually, after 10.9.2 update the problem has gone.

I have 10.9.2, same problem

As others have mentioned, this fixes my problem immediately each time.

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

sleep 5

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

I found zapping the P-RAM and resetting the SMC did the trick for me.

Proggie's software works properly. I bought Macbook Air 13" (Updated to 10.9.2, 1,3Ghz i5, 8GB RAM, 128GB SSD) on last week and this was second time the issue appears after whole night sleep. No sound after wake up. Just run Proggie's app and sound came back. I think it restarts the driver or something like that. Maybe Proggie could sort out what it does. 🙂

Thanks anyway.

Edit: Oh Proggie sorted out it already in earlier. It's a script.

I've created an apple-script app using the applescript code that was posted earlier, and it works very well. For those that are uncomfortable creating their own I can put it up in my dropbox if people are interested. I just put it in my doc and click it, enter the password and it fixes the issue.

You'll have to trust me that this is just the apple-script for this particular purpose and not a malicious program (since it does ask for admin password).

Proggie, thnk`s a lot! Your solution sve me from reboot) MacBook Air mid 2013. Good work!

Proggie's solution also worked for me. Great work around, now if only apple would fix the actual problem. Two thumbs up for Proggie!

It's ******* absurd that apple still hasn't fixed this. Also, most of the time now my little applescript (thanks to Proggie!) doesn't work--I get some method about kext instances not being able to be unloaded. Mass genocide of audio-related processes doesn't do anything either. The only resort is to restart. Makes me want to throw this MBPr 15 across the room and use a netbook.

In my case it look's like a problem of Boom. When turned off, everything works perfect.

Also it happens not just when waking from sleep, but sometimes even just removing or inserting headphones will kill the audio.
