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'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!

Can I ask did your MBA have this issue prior to you updating your OS to Mavericks i.e. when you was running Mountain Lion?

I was running Mountain Lion for about a month. I didn't recall having this issue but i do encounter the black screen problem. It is very annoying to be dealing with this issue for such a long time and i wonder when will they come up with a solution.

Thanks for the update, so this is probably a Mavericks thing, rather than a hardware thing.


In terms of when they will fix it, ha! Next time they release the new OS I would think, when it will likely be replaced by another issue of different nature. Things are slipping in days of late.

I have the same problem as well. Seems to be a huge problem for everyone and I cant understand why Aplpe havent fixed it after so many months after the release of 10.9. I switched to OS X for over 6 years ago from Windows because I was tired of all stability issues involved with it. For every year that goes OS X is just becoming more and more unstable as well. I use my laptop for mobile music production and hence very much in need for a stable sound. I waited months before upgrading to Mavericks because I know there is normally issues in the beginning of a software upgrade. But this fault makes me so f-ing angry so I want to go back to the old OS where things worked. The least thing the sect Apple could to is to acknowledge the problem.
