Hi there,

This problem is really getting me down. My imac has no sound, here are the facts:

I get a chime on start up
There is no sound on any other accounts
In Sys Pref>Sound it reads no output devices found
If I use the volume keys a grey volume bar appears along with a zero symbol

I have run a permissions check etc...
Have not installed anything lately

Has anyone got any ideas why this is happening?

I may try a re-install of 10.5, but looking for a better fix?

    A few things to try:

    http://docs.info.apple.com/article.html?artnum=300832 Mac OS X: No audio from certain multimedia content

    Trick/Tip: Open up GarageBand if installed then, open a program (optional).
    Quit out of the GarageBand app.

    "I have run a permissions check etc..."

    Etc mean you also restarted after repairing permissions? Booted from your Leopard DVD & ran the repair disk/permissions option?

    Thank you so much for your reply.

    Tried garage band (5) and got "CORE AUDIO: selected driver not found (-10202)"

    Permissions, well that is a good point, I need to do the boot up from my leopard DVD so thanks for the direction with that..doing it now.

    This might also be part of the problem:

    +Your digital out has been turned on. You will also notice a red light in the hole when this happens. Use a plastic toothpick to reach into the hole and around the 3 o'clock position try flipping the switch. An alternate method that has worked for some people is to plug and unplug the earphones a few times. This sometimes resets the switch.+

    Well not sure what fixed this but all is fine now.

    I think it was the garage band trick that sorted it as I booted garage band, got the driver error, shut down for the night and rebooted the next day and all sound is now working...

    So thanks Baby Boomer !!

    I have been experiencing the same problem. It seems to occur randomly. I have been able to correct it by restarting the computer, except for one time when I had to restart it twice.
