No sound out after wake up in Mavericks

Hey tacomodo,

I don't know if either option help's, because unloading the kernel extension worked for me once, but you could try these steps:

• did you try to kill your Core Audio daemon (e.g. with sudo killall -9 coreaudiod) first? Maybe that helps...
• otherwise you could check the instances of the Apple HDA kernel extension with the kextstat command (see https://stackoverflow.com/questions/17345305/unload-kext-which-still-has-instanc es) and unload them first before you try to unload the Apple HDA kext itself

@Shreyaskuthu -

What is Boom Developers and their update? Never heard of that but I might be just a big ignorant, only been using Mac for a year now.

Boom is some third party application (which is non-free and requires a purchase).

No sane person would ever use a third party product to solve a problem which is clearly the responseability of the product manufacturer. In this case Apple Inc.

Apple should have fixed this issue a LONG time ago.

I agree.

I'm not even going to download a FREE app to solve this issue. It should be a genuine Apple update.

Once again guys, please let me know if my temporary solution helps you.

Cheers

I waited this long to upgrade and there's still a problem like this??? Egads…

Force quitting Coreaudiod doesn't do anything for me (well, it started an interesting chain that caused the most bizarre crash I've ever seen in which my screen eventually went all light tan, then seemed to log me out… but not enough that it fixed the sound issue, so will be officially restarting shortly, but I digress). Restarting fixed it when I first found this out the other day, but that will get annoying REALLY fast as I have numeros applications open at any given time (and several are Adobe, which don't just "quit" when you tell them to…)

My sound prefs are normal, never heard of this "Boom," so that's not it… even tried sticking in headphones in case it was doing that "oh, there's not an external speaker?" thing. After sleep sounds about right, as I had sound earlier, but not after it happened to fall asleep. I'm on a mid-2009 MBP, so it seems to go all over the place on what it will effect.

Hopefully there will be a solution some day…

Click airplay icon on top bar, choose: open display settings, disable airplay screen in dropdown menu. Now sound should be working again 🙂

I've tried everything to fix that problem.

How do i execute a command ?

Help please!

Same issue here:

MBP mid-2012 Mavericks 10.9.1. Only reboot is temporary workaround.

Apple please...

OK… weird… For the heck of it, even though I was 99.9% sure I had tried the AirPlay mention before (except through sound prefs, not via a dropdown since I'm a mid-09 and don't have mirroring abilities) but I tried clicking on the AirPlay option and then back to Internal Speakers a few hours ago on a whim and it worked…

I noticed my computer had gone silent again a few minutes ago, so went back to Sound prefs and tried it again… Oddly, my sound can come out of my AppleTV at the moment, but it won't come back to my computer…

Reboot still being the only consistent fix. Definitely a problem with Mavericks as this never occurred in 4+ years until I recently upgraded…

I encounter this with my Mac mini 2012 recently. What I did is simply enabled the 'power nap' in the system preferences.

So I disable it now and I think it will fix it.

Have you had this issue always i.e. before updating to Mavericks or just after updating to Mavericks?

Hi Supreem,

Just encountered this problem today. I've never had this issue before Mavericks.

That's good to know as at least you can write-off the possibility of it being a hardware related issue.

I have the same problem with MacBook Air Mid 2013 i7 8GB RAM 256GB SSD.

Has anyone found the fix to this?

Thanks!

This works for me. Just disable "Power Nap" then everything will be fine.
