    Hi guys.

    What can it be when I have no sound after waking-up my iMac (21,5'' mid-2011 base model) ?

    I can change volume settings with F11-F12 buttons but there is no sound at all.

    I can restore sound by put to sleep my iMac with POWER button and wake it up again.

    What can I do about it ?

    Plug in headphones and then unplug them.

    Reset the SMC.

    Get some headphones or external computer speakers.

    If you google "iMac smc reset", it's the first result that comes up.
