    Hey all,

    I've recently (today) just lost all audio on my 2012 iMac.

    I get no sound in either OS X or my Windows Boot Camp partition, not even a start up chime.

    I've checked the following:

    1. Volume Levels/Mute
    2. Rebooting
    3. Disk Permissions
    4. Hardware Diagnostics (D on bootup - all report clear)
    5. SMC has been reset
    6. PRAM Zapped
    7. External Speakers tried - also nothing

    I think I'm due a trip to the nice people at Apple, but I wondered if anyone had any great ideas before I take her in :) Thoughts greatly appreciated in case I've missed something.

    Go to the folder /Application/Utilities/ and launch the program "Audio MIDI Setup" and in the 'Output' tab 'Source' 44100 Hz and tweak the settings until you get sounds. See if that helps, Good Luck.
