No audio when waking from sleep - 27in iMac 2010

[Lit Up*]

As the title says. Sound gone when woken from a sleep which I initiated (ie, it doesn't seem to happen when it sleeps itself, as far as I know). Any ideas how to fix this? I'm hoping for a fix whereby I can kill a process and not need to restart, or something... thanks

restart and reset PRAM (Command option P R) during startup...

create another user account, see if it does the same thing..

Have you tried just to hit again play? Might be that simply Itunes stops playing when your computer goes in standby...
