Hello All:

Out of nowhere, or perhaps after airport security dropped my PB [15-inch 1.5gHz], I lost all sound. Literally. In the Sound preferences pane, there is no sound output device. iTunes won't play, because it sees no sound device. I called Apple, and after trashing sound prefs, doing all sorts of disk repair work, running DiskWarrior, doing the MIDI Audio check [no sound device, so the tip doesn't work], etc., Apple sends me a repair box.

I take a working PB, set it up as a target disk, and as soon as I run Carbon Copy Cloner and replicate the drive I am about to send to Apple, all sound is lost on the backup PB. On all accounts. Suddenly this does not sound like a hardware failure.

Before I send my PB off for a meaningless motherboard replacement, anyone have any ideas? Thanks.

[BTW, I have no APE files or extensions on either PB.]

Not exactly your problem, but this might help...

what happens when you boot from an OS X install CD?

Prior to sending it in, definitely boot from a different drive to test it, or reinstall the OS.

At times I'll lose sound after playing WoW for a while, but killing coreaudio and/or logging everyone out returns things to normal. It doesn't sound like that's happening to the OP, though.
