No sound after sleep

same problem mbpr late 2013, mavericks

I have the same problem with MBP retina late 2013, OSX 10.9

Similar problem here on my rMBP 15" late 2013 ... but it's not completely broken (as in no sound at all). The sound comes out distorted once every second. Anybody know a solution to this?

Here's a little video of the problem, using ableton live. The problem is system wide though.

This has nothing to do with your model. I have an a tower xeon quad core. NO sound with Mavericks. I need external speakers.

I have the sam problem with my late 2013 MbPro with external Harmon Kardon speakers and sometimes no sound after waking from sleep without a reboot. Have not found a solution to the problem.

Same problem here.. but internal speaker does not work either.. unless I restart. Just started today. as soon as it sleeps - then awakes there is no sound

Since my MacBook Pro Retina is new, I checked with "Applecare" to see if they had any suggestions. As of now they have none. I have reset SMC and PRAM with no effect. I rarely use headphones or external speakers so this is not a big issue for me. I doubt it is a hardware problem but that is just my uninformed opinion.

I think it is the software issue. I let my laptop sleep while the headphone was plugged in. After wake up, the sound was gone almost. Sometimes the first wakeup does not cause it. But if no headphone plugged in, it never happens. That is what happens with my newest Macbook Pro retina late 2013 running OSX Mavericks. So, my solution is to pull out the headphone before my lap goes to bed.

I have one last experiment to try. Before sleep I will disconnect the power supply but leave the external speakers/headphones attached and see if that has any effect on resolving the problem. I know from using the Console app that a lot of thing are still working while in sleep mode. Perhaps in battery mode there are less "things" going on.

Have had the same problem. No sound after coming out of sleep mode. It doesn't always happen after the first sleep process. But if i do 2 or 3 sleeps then it is guaranteed to lose all sound.

Went through all the help steps with apple care. Still didn't solve the problem. Definitely an annoying bug. Basically you have to reboot to get the sound back.

Also, I notice that the sound issue is worse using google chrome browser. Sometimes if my sound goes dead and I don't want to reboot to see a youtube video, I just open up firefox and the sound works in there.

Other times, the entire system loses sound (like right now as I'm typing this). So **** annoying!

Apple needs to fix this ASAP! 😠

I have the same problem with MBP retina 15'' late 2013, OSX 10.9.

Why apple does not care about this problem? I am tired of this!

Check the latest update 10.9.1

Lots of people say the issue is fixed

Did not see this update. I will check it. Thanks!

The same problem stil exists after the update to 10.9.1 and also can not be fixed using a terminal command from a recent CNET article by Topher Kessler on how to reset your sound system.

So if my sound stops I must reboot or never put the laptop to sleep with headphones or speakers attached. I have no idea how long the computer must sleep before the sound output dies but it takes a while. AS I said earlier, a lot of things are still running when sleep mode is on. Leave your MacBook Pro in sleep mode overnight and check the time stamps on your console logs the next morning and you will find a lot of stuff logged while you were sleeping.

There is one thing left out about the command prompt fix above. While it didn't revive my attached external speakers it did allow the sound to return when I disconnected the audio cable from the external port. The internal peakers started to play again which didn't happen before without a reboot. Reconnecting the external speakers or headphones again did not make any sound. When I went to check the sound setting in preferences the sound was set to audio out rather than internal speakers but the mute box was checked. I don't recall noticing that in the past and don't know if it had anything to do with the audio reset command that I typed into Terminal. When I unchecked the mute box the sound blasted out at a very high volume and everything is normal now without requiring a reboot. I will have to wait until tommorrow and see if it repeats the same phenomena again. Apple still has to do something about this problem.
