No sound out after wake up in Mavericks

I have updated to Mavericks three days ago.

But I find that there is no sound output (headphone &speaker) after sleep, even though for 1 second's sleep.

Everytime I need to restart the computer to obtain the sound again.


Someone list the following suggested solution, but it actually does not work:


"

Close all windows and quit all applications.


Click "Go" menu in the Finder menubar.


Select Computer, then Macintosh HD > Library > Preferences


Open "Audio" folder.


Right click these two files and select "Move to Trash".


com.apple.audio.DevicesSettings.plist

com.apple.audio.SystemSettings.plist


Close the window. Restart the computer.

"


I really really hope someone can help me to solve this problems.


Many thanks!

MacBook Air, OS X Mavericks (10.9)

I just bought a brand new MBP. Same problem, particularly with the headphone jack and sleep/awake. I'm on a clean install and verified no virus/malware/file corruption.


I'm using

Operating System: OSX 10.9.2

Processor: 2.6 GHz Intel Core i7

Memory: 16GB 1600 MHz DDR3


Proggie's app works, although with an error for me. Good on you sir.


Very disappointed in Apple for not fixing this in updates sooner.

I'm using am mid-2011 MacBook Pro, and the reason for spending that much money on hardware was that I was deeply frustrated about Windows' poor and unstable audio support. I couldn't have been more happy about my new hardware (running MacOS Snow Leopard at that time).


Until I upgraded to Mavericks.....


Things couldn't be worse, and I wish I still had my old Windows notebook. I went through 10.9.1, 10.9.2 and 10.9.3. Still I do have no sound after wake up from sleep. Workaround: close all applications that use coreaudiod, kill the process and then restart the apps. Absolutely annoying and time consuming, but at least it works.


In terms of (in-)stability, MacOS can finally compete with Windows, and for me this will definitely be the last piece of apple HW for a long time.....

Suddenly no sound when turning on Boom (1.9.1) or its Equalizer slider.


Tried deleting all files with references to Boom, redownloading and installing Boom, even tried reverting to earlier versions. I'm on 10.9.4, on a 2.7Ghz Intel Core i7, 16 Gb RAM. Reverted to an old backup of my HD with Mountain Lion and Boom on it, and worked perfectly, so I guess no hardware problems on this machine, nor audio port headphones problem in this case. I've had to deal with that red light sensor not turning off when headphones are removed, in the past.


I think this may have begun with a recent Safari (7.0.6) and an iTunes (11.3.1) update.


Tried the various solutions on offer on this thread. Nothing worked for me, apart from disabling Boom. Then sound to my internal speakers is fine:


0. Opened 'Audio MIDI Setup' and check volume control levels under input and output. Please make sure to uncheck Mute. Check the same under System Preferences->Sound. Tried with and without Apple TV.


1. Searched and deleted these files:

/Library/Preferences/com.apple.soundpref.plist

~/Library/Preferences/com.apple.soundpref.plist

/Library/Preferences/Audio/com.apple.audio.DeviceSettings.plist

/Library/Preferences/Audio/com.apple.audio.SystemSettings.plist

and then:

Shut down your Mac.

Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.

Turn on the computer.

Press and hold the Command-Option-P-R keys before the gray screen appears.

Hold the keys down until the computer restarts and you hear the startup sound for the second time.

Release the keys.


2. Aram's patch:

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

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


3. This other option just turns Boom off:

sudo killall coreaudiod

or Force Quit it in Activity Monitor.


4. Did a hard shutdown/reset by simultaneously pressing "Shift" "Control" "Option" keys with your left hand and at the same time pressing the "Off" button in the upper right hand corner of the keyboard.


5. Tried re-installing Mavericks.


6. Tried repairing permissions.


7. Reset NVRAM on Mac.


8. Reset the System Management Controller (SMC).


9. Tried everything Boom support suggested.

Uninstall Boom within the app via Settings->Preferences->Uninstall. Next. delete all Boom copies including the DMG files, and support files with Boom or Global Delight in the filename. Now, reinstall a fresh copy of Boom via our website www.globaldelight.com/boom and check if it helps.

I'll check back to see if anyone finds a fix. Off to file a bug report with Apple. https://bugreport.apple.com/

The only quick fix I've found so far is to force quit the coreaudiod process more than once. For a quick solution I made an applescript app that will automate this process, so you only need to run the app and wait for a few seconds. https://www.dropbox.com/s/05cugjo5f2q36h2/FixAudio.zip?dl=0

Disclaimer: quitting out of coreaudiod requires admin privileges, which is why the app requires a password.

I tried two days but often also before.

I did not realized that it could be something else than settings; that it could be hardware.

I saw in sound setting that the Digital Out/Optical digital-out port was selected when headphone was unplugged.

I tried with tooth pick, ... Not worked.

I bought a Dry Air Spray. Sprayed inside and immediately Built-in Internal speakers came back in sound setting. So, just a dust issue.
