Hey guys, really strange problem I am continuously having since installing Lion. Works fine throughout -- then all of a sudden, something like Safari or Chrome crashes, and sound stops working after that. And I don't just mean sound on YouTube or elsewhere on the web -- but Lion loses the ability to play any sound at all, be it on a website or an mp3 file on my hard disk. Not like my sound icons are greyed-out either -- volume up and down works fine but to no avail. To fix it I have to restart the OS every time which is very annoying as you can imagine.... anyone else have this problem? Any solution would be greatly appreciated.
