I have a mid-2010 iMac with Lion installed. Ever since I upgraded to Lion a few days ago, I've had no audio in YouTube, Hulu, Vimeo, Pandora, etc.


Also, no audio in VLC - which unlike Youtube, etc., is not a streaming video program but a downloaded program that runs on my computer, not streaming.


I'm using the default internal speakers that come inside the iMac.


The audio works fine with iTunes, Google Notifier, and iChat, and I can hear the normal "boops" when I raise or lower the volume via the keyboard or menubar.


The internet problems happen in Chrome, Safari, and Firefox.


If I restart the computer, audio works fine again. But when the computer goes to sleep and wakes up, the problem returns.


I have Flip4Mac and Perian installed if that info helps.


Plugging in and unplugging headphones doesn't help.


I've seen some discussions where people have no sound on the entire computer; that doesn't appear to be my issue.


Any suggestions?

iMac 21.5, Mac OS X (10.7)
