Hello.  Since I upgraded to Mountain Lion, I have the persistent problem of my system sounds not working, after my laptop sleeps.  Fresh after a restart, they will work..then, after screen saver or sleep, they will not. 


Here's what doesn't sound:

- Apple mail sounds (sending, receiving)

- alert sounds

- Sys Pref -> Sound -> any/all sound effect selection

- screen capture click



Here's what always works fine:

- the pop-pop-pop sound when I increase/decrease the volume

- iTunes

- any sound from audio/visual embedded in browsers

- sound from all 3rd party apps



Internal speakers are selected

No problem throwing out sound to airplay, etc.

No problem with non-system non-Mail sounds

All sounds work fine after a restart...but after a sleep or a screen saver, they will cease working until the next restart.


MacBook Air, 10.8.1 (also was noticed under 10.8)

1.7 GHz, 4 GB


I do see posts where people are experiencing the same, but no real solutions.  I have found & trashed the prefs file (from other posting solution) but that did not solve this persistent issue.  The sounds always DO work fresh after restart...just after sleeping, they do not.  Thank you  :-)

iMac/MacBook/iPhone, Mac OS X (10.6.3)
