No Audio from Mac

[LastLine]

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.
