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 have the sleep sound problem thingy and also have Boom installed. I suspected this was the issue.


I'm having A MacBook Air, 2014, and have Mac OS Sierra.


This is what I did.

I quit boom before I put the compute on sleep. I didn't run the other steps. Still, I have this problem. Furthermore, the internal speakers don't show up in the system preference>sound>output or input.


I have not read all the posts on this thread so do not know if a solution has been found on this since posting this in 2013.

I have the same problem. But i need to let the macbook sleep for quite some time before the sound will fail. However I chatted with the Apple support folks and they provided a fix for now. Go to system preferences, under energy saver, remove the checkbox for "put hard disks to sleep when possible". It seems to work for me. Does it work for u guys?
