After doing a number of updates, my audio after sleep stopped working. I had bulk run some updates, so had no idea what broke it.
So, I went back to my 10.7 clone image and restored it. Then applied 10.8, and it still worked. Left it that way for a week, then tried the quicktime update. Aha, now audio is gone after sleep again. So, I *think* the quicktime update caused the problem.
I'm still using the DellEFI For 10v to update extensions, and did not want to have to go back and re-install the whole system again just to use the netbook installer. Maybe I will when I have lots of spare time.
Any ideas as to what might have broken?
