    I know this has to be an easy fix but..

    I can't get an y sound on my Powerbook. I use the sound keys above the "4" and "5" keys and it shows a full bar but has a O with a / through it. How can I get the sound back on?

    Ok this problem fixed itself automatically the last time after a few days.

    It is doing it again. I notice that there is no volume control at the top of the screen. I can't click there and nothing happens

    Can you open up system preferences and click on the sound icon. All your setting should be there. Also try repairing disk permissions in disk utility.

    From the look of your image it looks like it muted. What happens when you hit F3

    Did you reset the PMU/PRAM yet?

    1. Go into the folder Applications/Utilities and open the ‘Audio MIDI Setup’ app. Check the properties for ‘Built In Output.’ It might be set to 96KHz. Change it to 44KHz. Make sure the Default & System Output options re set to ‘Built-in Output.’ Next, where it says ‘Properties for:,’ make sure it’s set to ‘Built-in Output.’ Last, make sure the option for ”’Source:’ is ‘Internal Speakers.’

    2. Reset your PRAM.

    3. If you have a laptop with no sound, check your output jack on the side. Is there a red light on inside? If so, the analog/digital switch is stuck and the laptop won’t have any sound. Take a wood toothpick and insert it gently in the output sound jack and press gently downwards until the red light (LED) is off. You should have sound again. If you can’t get the light to go out, you will have to have it serviced. Contact Apple.

    5. Try cleaning your User and System cache files with a utility that’s compatible with Leopard, like Cocktail 4.0.1 or Leopard Cache Cleaner.

    4. Try deleting the following files after cleaning cache files:

    /System/Library/Extensions.mkext
    /System/Library/Extensions.kextcache

    Here is the results of the disk utility repair permissions. I assume I repair the disk now?

    I will also try your suggestions from above

    Here is what I got when I went to the Audio MIDI setup. I could not change anything. Everything is greyed out and the "Default output" and the "System output" had nothing else to choose from in the drop down menu

    You should repair permissions at least once a month. Here is a nice program I use http://applejack.sourceforge.net/

    Why do you need a screwdriver? Use coin to remove the battery.

    Yeah I caught that after I posted. I am retarded.


    I reset the PMU and it didn't work
    The output jack looks good
    So now I will need to move on to cleaning the cache.
