High,

Suddenly i have no sound. I'm running Panther on a Pismo
and everything was working fine until tonight when iTunes
locked up. I tried to force quit iTunes but it wouldn't shut
down so i forced a re-boot. When my system came back
up i had no sound. The Sound Utility detects no sound
hardware and the Audio/Midi set up app crashes.

What needs reinstalling here?

Thanks,

JPW

Low,

I'd try re-installing everything. If your system is having problems of that magnitude, and you're fairly confident that you're not having any actual hardware problems, format your drive and do a clean install of everything.

Personally, I think that trying to solve your problem through a process of elimination, would be more hassle than it's worth. If you have important files on your pismo, back them up on another drive, computer, CD, whatever, and do a full format and clean install.

Go nuts...

Gay men don't jump.

If you haven't already solved your problem I might have a
few suggestions for you to try. First is to go to your
System Preferences and see what the sound panel lists for
output options. I have seen some machines where the
wrong output was selected or the volume was turned
down here.

Next, if that doesn't work is to restart your computer and
as you hear the optical drive click you need to hold down
the 'P' 'R' 'option' and the clover/apple key right next to
the space bar for about fifteen seconds. These four keys
held down together during the boot process will reset
something call the PRAM which hold the different
parameters of the computer, including sound.

Third, try to plug either headphones or speakers into the
audio out jack. If sound works there and not from the
speakers on the computer and you have determined it is
not a software setting by the two methods above then I'm
afraid your internal speakers are no longer working.

If these simple solutions did not solve the issue I would
follow Albert's advice about the reinstall of the OS.

Good luck!
