Core Audio Error Code -2

Hi -

I just got my new 2 GHz Core 2 Duo iMac up and running but I don't get any sound from it. The boot chime works, but by the time it is all up there's no sound at all. The speaker icon disappears when I click it and the button for it on the preferences page gets unselected. Another thread said to boot Garage Band for a fix, but that gives me a Core Audio Error Code -2 dialog box. Also, nothing will play in iTunes either. Did any of you ever have this and/or know a way around it?

iMac Core 2 Duo, Mac OS X (10.4.7), no sound

Yikes, more audio woes. Between Friday and today (Sunday) my MiniMac has developped this exact same problem. I've installed nothing. The speaker icon spontaneously removed itself from the Finder bar, I reselected the checkbox to put it back and there it now is, but silence still reigns supreme. Audio worked fine after last weeks x11 updates. Firmware is up to date. Any ideas?

This is crazy. I closed the MiniMac down, unplugged the mains cable, re-connected it, and re-booted. The boot up chime (previously absent) returned, and all audio was back to normal.

Eh????

You may need to adjust the configuration in Audio MIDI Setup.

From Mac Help in the Finder Help menu;
You can use Audio MIDI Setup to configure the audio input and output devices you use with your computer...open Audio MIDI Setup, in Applications/Utilities/Audio MIDI Setup.

The default setting for Properties For: Built-in Output should be Source: Internal speakers, 44100.0 Hz, 2ch-24bit
