No Sound on Powerbook G4? Help.

[JesterJJZ]

A friend of mine is having trouble with her 13" Powerbook G4 running Leopard. When you click the volume and mute buttons the volume overlay appears and all the bars are off and there is a "cancel" (circle with a slash) icon under it. In the sound preferences there doesn't appear to be any options under "output" It's empty.

Any takers? I've never seen anything like this before.

It's like the computer thinks there's no sound card on it.

I haven't tried repairing permissions yet, I'll tell her to try that tomorrow.

Thanks!

Well...repairing permissions didn't seem to work.

Did you try to reset PRAM/NVRAM?

I'm assuming its a 12" PowerBook and not the bigger 15" brother or MacBooks.

Any way try resetting the NVRAM and PRAM on the system and see if that helps any.

1. Shut down the computer
2: Press the power button and hold the following key combination:
Command + Option + P + R
3. Hold the buttons until you hear the "bong" (if the audio issue is hardware you may not hear it).

If the internal speakers still are not listed in the sound preferences then your friend may need to reinstall OS X.

I had this problem on my G4 Powerbook after the Leopard upgrade. A simple restart fixed the issue. Make sure all upgrades are installed, whether you're running Leopard or not.

Yeah it's a tiny Powerbook, must be the 12"

Rebooting does nothing. Any idea why this would happen? Reinstalling the OS is not something she'll want to hear.

Thanks!

Try opening GarageBand and see if it does anything. When GarageBand is opened, it resets CoreAudio on the computer.

Now, there's something I didn't know!

What are the Audio setting ins the sound control panel set to? Maybe this would help.

Nothing...there aren't any devices listed...no speakers, lineout, headphone, etc...nada...it's blank.
