Hey folks,
I'm unsure as to whether this is hardware or software problem so apologies if this does turn out to be software..

I've recently been experiencing loss of sound on my Powerbook. I can adjust the volume with the volume keys or control panel but nothing comes out the speaker. Checked the settings in teh Sound Control panel and they seem ok. but no sound.

Logging out and such won't clear it up.

But the strange thing is that every time after I restart to clear this up (restart ALWAYS clear it up) I get a Black on Grey message just after it finds the system on boot saying I need to restart (I believe this is a low level message).

Anyone else experience anything similar or have any pointers as to what this could be? I've run First Aid and Hardware test recently.

Cheers
Pring

Sounds to me like you may need to reload your OS. I've had problems like that in the past that won't go away until I completely reload.

One time however, I did have a CD-ROM drive in an eMac that seemed like it was a software problem that was really a hardware problem.

Could it be the sound card is not waking up after the laptop wakes up from sleep? I've heard someone else mention the issue.

I had a similar problem on my old B&W G3. The best suggestion I can give is boot up from the CD, run the disc first aid utility as well as repair disk permissions. If you were to have to do an archive and install of the system since you couldn't solve the problem, it would be easy to do. The next step assuming you still can't get anything to work is completely erase the hard drive. I'm assuming you've plugged in a set of headphones to see if it is just a speaker issue? Also, reset the PMU (go to Apple's PB support site for instructions) but also reset the PRAM by starting up the computer while holding down the Apple-option-P-R keys and waiting to hear a startup chime three times. Goodluck.

Yes sorry, should have said. Sound doesn't come out of the line out either. I'll try your suggestions and let you know the outcome.

This is a kernel panic, and you should not be getting one each time you restart the system. I think there is an article somewhere on Apple that discusses common causes of frequent kernel panics in powerbooks, though I don't know of its exact location.

My question would be, have you recently put any haxies on the system? If so, maybe try deleting them and see if ti helps.

Have you tried repairing permissions?

Then failing all that and what was previously mentioned, I would suggest reinstalling the OS by archive & install.

Personally I would be more concerned about the kernel panic every time you restart, but the two problems are more than likely related to each other.

So tonight after installing the 10.3.5 update (which I secretely hoped might solve the problem) I decided to start up in Verbose Mode (Command-v.. the system spews out info while starting up). It seems the kernel panic on startup occurs due to a problem with the IONetworking package, seemingly to do with Airport.

I think a Archive and Install is on the cards as soon as I have the time... if that doesn't solve it then things point to something more sinister with my Airport card.

Thanks for all your help everyone

Have you tried re-seating your airport card? Especially moving around they can become a little loose, and it is a common cause of kernel panics.
