I don't know how long it's been like that exactly, but for the moment my TiBook 800/10.2.3 stubbornly refuses to play sound. Any sound - QT, DVD, system.

I've tried
- deleting all sound prefs I could find
- deleting all system cache files I could find
- logging in using another account
- resetting PRAM
- sleep and unsleep the box with carious intervals, from2 seconds to 10 hours
- plugging and unplugging headphones.

OSX has crashed with kernel panics quite a few times the last days, especially using/changing the System Prefs (mouse, sound, time zone), and I'm beginning to get that nagging feeling it might be time to re-install.

Of course, I'm in Sydney right now, exactly on the opposite side of the world as my Jaguar disks, so any help in that matter would be greatly appreciated

tough one - would make sure you have no extra hardware attached (or maybe pc card, extra RAM?), and try the disk:repair permissions and fsck the disk a few times. only things i can think of.

Thanks for the reply.
I did all of this already... fsck, booting from an external FW disk I brought with me and then checking/repairing permissions on the main disk.

There is no other extra hardware attached -- none new, that is; it's been working fine with the 1 GB non-Apple RAM for 2/3 of a year now.

Last things I did before I noticed I'd lost all sound are:
- installed Nikon View 5 (blechh!)*
- installed the latest WindowShade*
- used Carbon Copy Cloner to Clone the drive the the FW disk, repairing permissions beforehand.

* uninstalled since, including APE.

What I'm unsure about is... doesn't Apple System Profiler show Audio and other I/O devices somewhere? When I start it up now, I can find no mention of any I/O chipset, audio hardware or anything.

the system profiler won't show any audio detail (unless you have usb speakers or something) so nothing to worry about there.
a complete stretch, but is energy saver screwed up? on battery 'books will cut power to audio circuitry when not used. maybe trash energy saver prefs?
also would make SURE ape is gone entirely...

sorry - am really reaching here. sounds like reinstall is called for.

Now that you mention it... Energy saver did (kernel-)crash on me recently!

Off I am finding that pref...

workerbee · Feb 1, 2003, 08:40 AM

Didn't find any Energy Saver pref file. Changing settings in System Prefs, Quitting and logout-login didn't change a thing. Golden silence still prevails

Restarting after using the FW disk as boot disk, LaunchBar scanning did a short and very ugly sort of beep/honk, so I guess the speakers still sort of work.

Well, at least I didn't go wild on pirated DVDs (King of New York, Chicago, the 3 Indiana Jones', Star Wars IV-VI...) in Kuala Lumpur.

i have been noticing my cube going mute too lately. i just pull the usb cable out put it back in and they come back on. i know that doesn't help you but just another sound issue.

workerbee · Feb 1, 2003, 08:47 AM

Hmmm... System Profiler / Frameworks lists "AudioUnit.framework", changed December 18 2002 (10.1.3?), Version: not available. Except for the kernel.framework, that is the only framework that has no version information available.

No USB attached at the moment. I'll try to re-attach and de-attach that Nikon DigiCam, and if that does not help, go to tHE Sydney Applestore and attach SoundSticks there (like I have at home: they seem to frequently put OSX into a state of uncertainty).

Maybe it's time to get analog speakers.

you haven't pressed the mute key have you?

I did, but nuthin' happened

Do you get any sound in OS9. My first TiBook400 lost all it's sound too and it had to go back to Texas for a new motherboard. You may have a hardware problem. Booting in OS9 is a good test for whether it's the software or the hardware a lot of times since totally seperate software is running.

Excellent idea... thanks! I'll try tomorrow evening, since I seem to have a SSH connection up and don't know if I can simply re-login to that.

Me and Unix and those protocols...

My iMac does a similar loss of sound occasionally, like this morning. I unplug my Apple Pro Speakers, then plug them back in.

My iBook also did it the other day, I rebooted and all was fine.

Both were using 10.2.3. It's annoying.
