That might be the problem. The audio only supports one device at a time, and mutes others while additional devices are connected. Check your system preferences to make sure the correct device you want to use is selected under Apple menu -> System Preferences -> Sound.
Energy Saver may interfere with this, as many third party USB devices are not Energy Saver aware, and only rebooting fixes it when Energy Saver causes a problem.
Thanks for the suggestion.
It doesn't look like Energy Saver is the problem because once the problem starts, not even rebooting helps. The only thing that helps is to delete some plists, unplug all my USB devices (printer, wireless mouse, external hard drive, mic/headphone set) and then reboot. I have tried unplugging the USB mic/headphone set alone and rebooting, but that doesn't help.
The USB mic/headphone set might indeed be part of the problem, but what seems to set it off is trying to update or charge my ipod shuffle. I have had to restore factory settings on my ipod a couple of times since I upgraded to iTunes 6.0.5 because iTunes wouldn't recognize the ipod (the icon showed on the desktop, but iTunes couldn't see it). So I think there might be something going on with the new iTunes software too.
Annyway, thanks for your suggestion.
