    After doing a fresh install of Snow Leopard on my 2011 iMac I dont have any sound?

    In the Sound option in Sys prefs the only listed Output device is "digital out"?

    The normal startup sound plays as I first turn the iMac on and sound fully works under Bootcamp/Windows 7??

    Seems like some software issue - anyone know how to fix this...

    Have done all Software updates..

    Tks

    You installed Leopard on a 2011 iMac? As in 10.5 Leopard? That is probably your problem right there.

    After much googling it seems this problem (no internal speakers listed in output device tab in Sys Pref) happens at times.. but no one really nows why..

    I did forget to say it only happened after I opened up my new iMac and installed a new SSD drive :) which works great by the way.. I also swapped out the 1TB hard drive for a 2TB one.

    So it seems I may have not plugged something back in - although I was very careful..

    There is the normal Apple chime sound when I boot the machine up but no sound after that..

    Sound fully works under Windows 7/Bootcamp.. :confused:

    SO obviously I plugged the speaker back in to get these sounds..

    Anyone know what other internal sensors or connections that could be giving this problem?

    Tks

    Reset your PRAM and SMC?

    Is there anything plugged into the audio jack? or a redlight coming out of it?
    have you tried option clicking the speaker icon in the menu bar and changing the output manually?

    and im assuming you used the restore discs that came with the computer and not the retail version..

    Tks guys

    Yes tried the PRAM reset - just get the normal Apple Chime sounds

    Reset SMC - isn't this just turning off, unplugging for 15 secs and turning on again? It didn't do anything for the sound issue.

    Tried plugging some headphones into the headphone socket and no sound there either..

    The only listed OUTPUT device in Sys Prefs - Sound is optical

    My External Bluetooth speakers work.

    Yes did a complete reinstall of Snow Leopard from the disc that came with the iMac..

    Any other suggestions?

    Tks
