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!
