No sound out after wake up in Mavericks

Experiencing the same problem (no sound), after just pausing spotify for a 5 minutes.

There was no sound in either the headphones or the internal speakers but there was an output device called G246HYL (you can option/alt click on the sound icon in the menu bar to switch) that worked even though it was only possible to play at full volume with that device. After rebooting it worked as normal again.

The same problem. I sleep my macbook retina 13 (late 2013) on everyday basis. After wakeup sometimes I have problems with sound - no sound here.

Installed all latest updates on my macbook. MacOS Maveriscks 10.9.1

Maybe problem occurs when I use my external monitor via HDMI...

Please fix this crazy bug!

Thanks.

Just bumping this. Same problem here. Bought mine in Q4 of 2013.

Running 10.9.1

11" Macbook Air / 1.7Ghz i7 / 8Gb / 500Gb

hey im having this problem too. extremely disconcerting. My 90 days tech support are over. Anyone call them and did they say they know/working on a fix? thanks

edit:I have a 13" macbook PRO retina late 2013 base model

Same problem here. After installing mavricks on a Macbook air 2013. Also having issues with the webcam after sleep mode. could use a little help. It comes back after reboot.

This problem is 100% reproducable on my new AIr. Just keep a video page open and the video on pause on my Safari browser such as YouTube. Let the computer go to sleep and when it awakes, no more sound.

Really, Apple? After, what, three months, this issue is not fixed?

I. Can. NOT. Use. My. Computer.

The least you can do is to acknowledge the problem and communicate some kind of plan to us (the users, you know?)

Hello everyone! Apparently this problem arises when using adobe flash palyer (but maybe not only) and in my case is of software origin.

However, there is a quick fix:

Close all apps using sound (iTunes, Safari, Facetime etc.), open terminal and run:

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

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

you may want to add

sudo killall coreaudiod

in the beginning or end. This restarts the audio server.

Or you can create an apple script for easier use. Create a new application in automator, select utilities - run applescript and paste this small script into it.

n run {input, parameters}

do shell script "sudo killall coreaudiod" with administrator privileges

do shell script "sudo kextunload /System/Library/Extensions/AppleHDA.kext" with administrator privileges

do shell script "sudo kextload /System/Library/Extensions/AppleHDA.kext" with administrator privileges

do shell script "sudo killall coreaudiod" with administrator privileges

return input

end run

You may also want to add the "close application" for iTunes, Safari etc. or "ask for confirmation" in the beginning. Then save this application to your desktop, change its icon and copy it to the apps folder. In time of sound troubles launch it. It will prompt you for your password and restart the sound.

Good luck!

Yes, I agree that ptoblem is with Adobe Flash. I also made some experiments, and found that sound works well if I don't use web pages with Flash content.

But, when I run Grooveshark in web browser to listen to music - I see the ptoblem with sound after my macbook wake up after short or long sleep.

I think that Apple tech guys can find the problem with Adobe Flash and prevent this issue with sound. It's strange that third-party application creates problem for core of orepations system.

I believe that this problem will be solved in next release of Mavericks. Maybe in 10.9.2?

This problem is near 4 months f*cking old.

woccz2013'ssolution was the only solution it worked for me without restart, or resetting PRAM or whatever

(I didn't want to reset just to get back sound 😀)

Close all apps using sound (iTunes, Safari, Facetime etc.), open terminal and run:

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

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

you may want to add

sudo killall coreaudiod

in the beginning or end. This restarts the audio server.

Restarting Chrome worked for me. Try it too, before you go to more complicated solutions.

Any response to this? The quality of Apple's releases continues its nosedive of the last few years. Does QA even exist anymore? This is laughably easy to reproduce.

We know these products are built to fail but I at least expect it to be working when I've just got it. Don't expect another £2k from me any time soon!

Bumping this as I'm now experiencing it.

Had my macbook 3 years and only now has it started doing it, coincidence I've recently started using chrome for netflix?

No way am I ever getting another apple computer.

I've lost count on how many times, i have encountered this problem of losing audio. It's been about 5 months since i've got my MBA mid 2013, up until now this problem persist. Hopefully your programmers could come with a solution for this PERSISTING PROBLEM ASAP!
