Sound on iBook G4 is dead

A few months ago I was on my iBook G4 and suddenly my sound died, also my microphone stopped working as well. I think it happened right after I upgraded iTunes.
system.log reports
May 17 19:00:07 ibook kernel[0]: Sound assertion "0 != err" failed in "AppleLegacyAudio/AppleTexas2Audio/AppleTexas2Audio.cpp" at line 960 goto
Exit
Any ideas?
I searched all over the net and I found people with similar problems but no solution.
I tried resetting pram, nram, and a few other types of resets..

Ok I did what you said, however searching for AppleDallasDriver.ktext didn't yield anything, but I know it's located in the extensions folder, so I deleted it and made a copy of it. Now when I restart I get an error message stating:
"System extension cannot be used.
The system extension "/System/Library/Extensions/AppleFWAudio.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update."
I deleted that extension as well (AppleFWAudi.kext) and restarted, and still no sound and access.log still says the same original error "ibook kernel[0]: Sound assertion "0 != err" failed in "AppleLegacyAudio/AppleTexas2Audio/AppleTexas2Audio.cpp" at line 960 goto
Exit"
Also I just noticed my sound preferences has another device called "Aggregate Device"
I don't know what that means

=( My iBook is still dead!!! (with included symptoms of a dying iBook)

I bought my iBook last May2004. I loved my iBook and took really good care of it. After one year of usage, all of a sudden my iBook stopped working -- a month after my warranty had expired... It all started with the "sleeping problem" -- when it didn't want to go to sleep even after my lid was already down... there were even times when it got really hot in my bag because it didn't sleep... then sooner the problem got worst... it wouldn't boot normaly -- it would boot 1 out of 4 times of trying to boot-it-up... I also got the weird screen with different funky colors... then one day, all I hear is my iBooks fan when I press the power button... I brought it to the Mac Shop in the Philippines and they are charging me about P30,000 ($555-US) because they said it "might" be the logic board. I decided not to get it fixed here because I couldn't afford such amount... when I went to pick it up and got their invoice, their invoice mentioned "probable logic board failure"... the word "probable" kinda smells fishy... did they really check what was the problem?... ANYWAYS,... 5 after I took it back from the shop I decided to remove the battery and let it sit there for awhile...3 months after, I used my power cord to power up my laptop and used my boot cd to boot up my iBook...supprisingly, it worked... then I decided to shut my laptop off and get my battery charging... after my battery was fully charged, i turned my laptop on again and it was still working... , i unplugged my power cord and left my laptop running on battery and it still worked...BUT,... when I got tired of enjoying my again working iBook, I put my laptop in a sleep mode by closing its lid... then its LCD lights didn't automaticaly turn-off like usual even if the lid was already down... so I opened it again and pressed my space button to try to get it running but now it just went to a blank screen... again, all I hear is a fan when I turn it on and that was the last of it working... what's up with my beloved iBook?... I personaly know 7 other people (friends)experiencing the problem -- not including those I've meet in the internet -- you don't wanna know how many they are. PLEASE HELP! MY iBOOK is still DEAD!!!!!!
Note: Phrases that are underlined and are in bold letters are the usual symptoms of a dying iBook G4. Believe me. I've search all over this discussion board since 2005 and all I see are people expressing their deep sorrow and grief about their dead iBook G4. I miss me iBook so much and all that is in it. It is still sitting in my bag waiting to be resurrected. A few days ago I planned to get a MacBook because I really missed my iBook, but upon stumbling upon this Discussion Board again, I still feel much dissatisfaction from both old and new users of iBooks and MacBooks -- from the same logic board issues. I dare you find it out yourself by surfing around this Discussion Board.
To those who are in my shoes: "I feel your agony"
To those who's iBook still works: "You're one of the lucky few...but just wait...huh."
To those who are planning to buy one: "True. iBooks and MacBooks are really cool with very cool design and very good OS. But my friend, think it over plenty of times. Im not telling you to not buy one but its really painful to wake-up one day and your beloved iBook/MacBook is DEAD and its now just as useful as a paperweight or probably a doorjam or maybe even a cutting board. Believe me, I know."
Unless APPLE would decide to backup their systems with a 3year warranty(WHY NOT?), I wouldn't....
Mr. Steve Jobs, Sir, with full respect, that's my dare to you.

IBook Rises From Dead After 3 Months! Baffled Family Member Needs Answers

Hi
This is a rather long-winded post, so apologies/thanks to those of you patient enough to read to the end and to anyone who can shed some light on something that is baffling me regarding my iBook G3 700MHz (mid-2002 - I think).
This iBook has been an absolute trojan, working virtually 24/7 since I got it.
Anyway, one day about 3 months ago it just wouldn't power up. Nothing. No sound, no movement or any other sign of life.
I called my local Apple dealer and they told me about the PMU reset (mentioned elsewhere in these posts), which I did, and lo and behold the old beast fired up again. There was much rejoicing. All I had to do was reset the date and everything was sweet.
A day or so later I turned it off to take it to work with me, as usual. When I got to work and tried to start up nothing happened. Dead.
I tried the PMU reset again, to no avail. Nothing would get it going again.
I took it in to the dealer for them to have a look at. When I phoned back in the evening they said the logic board was dead and would need to be replaced at a cost of AU$1,000 (about US$800)! When I asked whether there wasn't an internal battery that could be replaced, I was told the iBooks don't have them - a fact which seems to have been confirmed in other posts in this forum.
I decided to buy a new iBook.
I've been waiting now for over 2 months for my new BTO iBook, but the dealer has lent me another iBook to tide me over until it arrives. The ridiculous wait for my new iBook is something I can cover in another rant, so I'll cut to the chase now...
Today, I was tidying up and decided that i should put my dead iBook away in its box and maybe one day I'd buy a second-hand logic board on eBay or something, fix it up and use it as an iTunes player or something...
Anyway, just before I put the dead iBook into its coffin, I thought I'd just give the power button one last push, for old times' sake.
The beast started up!
Again, there was much rejoicing. Again, all I had to do was reset the date/time.
So, as I type this on my loan iBook, I'm listening to iTunes via my SoundSticks on the old machine.
My question is this...
What has really happened to my iBook?
If the logic board is dead, why did the machine start up again after 3 months lying dormant?
If there is no internal battery, why have I had to reset the date/time both times it restarted? Wouldn't it be logical to think that some kind of battery was storing these settings?
Doesn't it seem reasonable to think that there is some sort of battery inside the machine which has slowly built up enough charge over the last 90 days to allow the computer to boot again?
Is it that there is in fact an internal battery built in to the logic board, and when the dealer told me it was "fried", all they really meant was that the battery was dead, but because it was on the logic board that the whole thing had to be replaced?
Obviously, I'm not going to turn the old iBook off again. I'll just put it to sleep when I'm not listening to music through it, but I'm just wondering whether any of you really smart people can tell me what's going on.
I really feel that this is miraculous and need some kind of clear answers to these questions.
Thanks for any help you can give me.

Hi, Matthew. Welcome to Apple Discussions.
It is not uncommon for an iBook with a bad logic board to work intermittently.
There is no internal battery in an iBook. A capacitor holds the date/time information long enough for you to switch batteries, or for a short time without battery or AC power. The only battery is the main battery. If it has been left without use for some months, the capacitor has simply lost the date and time due to disuse and lack of power during that time.
When you do a PMU reset, this makes the time and date default, also.
Your iBook has been acting as one would expect, given the circumstances.
Mystery solved.

Why does my html widget not play sound in ibooks?

I've designed a widget that plays sound correctly in every other browser. It uses an AAC-MPEG4 with the .m4a file extension on all of the sounds. I know the code is working correctly because as I said, it works in any browser. I've checked to volume controls and speakers of the ipad, they work and are turned all the way up. I just wonder if ibooks somehow does not support the javascript .play() command...

Now, why can't I get this when I enter the code directly?
L.
This proves what I believed and that is you are not naming the file correctly. It has got a hidden file extension and if you were using Windows, I would have told you how to reveal the file names properly including hidden extensions of known file names. I know nothing about MACs so you have yto wait until Murray Summers or John Waller comes here. They know about Apple MACs and they have been in the business longer than anybody here.
In windows, if we want Notepad to keep the names as it is we normally name the file as:
"welcome.html" including the quotes so that Notepad will know that it is not the normal text file to be opened in notepad or wordpad (TWO text editors in Windows)
Perhaps you should use my file as a template and then change the text to:
<p>The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog.</p>
Hope this helps.

Ibook 12' inch dead

In the end of August my ibook went dead. When i turned it off, the screen is black and i can hear only my hard drive and the dvd drive which has a cd-rom inside which i can not eject. I have tried to eject the cd whith every option Apple's website suggests and also i have tried whith and without the battery on to start the ibook. What can i do now? The ibook hasn't closed a year from the date i bought it. Should i take it back to fix it or buy a new one?

. Should i take it back to fix it or buy a new one?
Have it fixed if it is still under warranty, but then I would seriously consider selling it afterwards. If you scan this help forum you will find a very high number of people who have to return their ibook to Apple many times for reapir after the first time. It seems very strange that once you have had a logic board replaced that you would ever need to have it replaced again, but this is quite common. The same applies to hard drives, keyboards etc.

No stereo sound on iBook G4

When I listen to music through my iBook, whether with headphones or through the computer speakers, it only plays through the left headphone/speaker. Actually, it plays very faintly through the right side. I have tried multiple headphones and media players, and the problem persists.
I just installed the latest Mac updates, if that matters.
Any ideas?

go under system preferences>sound>balance
for some reason it shifts the balance to the left sometimes...

Ibook is very dead

My ibook G4 doesn't do anything anymore. I've always been very kind to it, but it's suddenly dead. The battery still seems to be loaded (4 lights) and there is no visible problem with the power supply (green light), but when I press the on button nothing happens. Is there a way of formatting everything?

I have a brand new iBook (15 / 1.42 GHz version). The unit will only boot with the AC adapter plugged in. The battery appears to be charged with 4 green battery lights. I followed the PMU suggestions with no success. The screen is black, unit silent and totally unresponsive. With the power supply plugged in it works great but unplug it and the computer goes dead. I would like to be able to use the new unit without being tethered to AC power. I dont think its too much to ask for a new unit to actually work but maybe Im dreaming. Any suggestions?

Ibook hard drive dead

My friend has an ibook that she spilled some sqrite on several months ago (yes i know this is very bad) but it has worked fine since then and we have kept our fingers crossed. This week though the computer will not start and the genius at the apple store said the drive is dead, which is understandable. The warrenty runs out in january (she doesn't have apple care as of now) but that doesn't really matter because apple would not cover this anyway. My question is how can she fix it? She doesn't have much money so an expensive repair may be out of the question. I have thought about trying to put in a new hard drive myself seeing as how her warrenty is almost up anyway but i don't really know how hard that is, i've never reaplaced a laptop hard drive before. Ideas?

At the time of the spill all of the above cautions were taken. After a day or 2 it was turned back on and had been functioning like normal until this weekend. At this point it will start to turn on but when it hits the blue screen before the login screen it will sit there forever. I tried to run disk repair, but that gave an error. When i took it to the apple store today the guy plugged in a firewire drive and booted off of it then ran disk utility. When disk utility opened the ibook's hard drive showed up red, and the guy said that meant it was dead. He could tell something had been spilled on it and i told him it was a surgary liquid and he said that with sugar it doesn't necessarily destroy the circuit right away, but that over time the circuit could eat away at it and then could get messed up. So because the computer could boot off of the external drive at the store i infer that the motherboard etc is fine (at least for now anyway)

Short "car alarm" sound from Ibook G3

I have a dual USB Ibook that has started making the dreaded car alarm sound when waking from sleep, and sometimes completely randomly.. I have found it impossible to find anything about this issue until I read a similar thread here: http://discussions.apple.com/thread.jspa?messageID=1251153&#1251153
My question is: Why has Apple not written anything about this in their support forums?, it's a pretty straight forward thing by the look of it (your hard drive is about to implode!) The SMART status of the HDD is "failing", and I expect to have to replace it very soon. It would have been nice if a little more help regarding this problem was available, so c'mon Apple, write it up please? Thanks, Harry

Hi, and welcome to Apple Discussions.
As you may have seen in searching for information about your issue, this is a user-to-user forum, so addressing Apple here doesn't get the job done if you want to communicate with the company.
This happens so rarely that, apparently, an Apple Knowledge Base article hasn't been written on the phenomenon. It would seem apparent, particularly with the S.M.A.R.T. status showing as "failing," that it is just one more indication of the imminent demise of the hard drive.
There used to be a Feedback form you could fill out for such requests, but since iBooks are now discontinued, the Feedback form is gone.
If you would like to make a comment on another product's Feedback form, they are available here:
http://www.apple.com/feedback/
The closest would be the MacBook, but they have a totally different drive (SATA instead of ATA), so the siren may not even happen on them.
Good luck with your new hard drive.

Epub sound on ibooks (exported to epub (fixed layout)

I download this exercises files from adobe.com
Add interactivity to fixed layout EPUBs | Adobe InDesign CC tutorials
then i export the file to epub (fixed layout), this works perfect in my iMac iBooks, but the sound don't work in my iPad iBooks, any idea?

Hi,
There is an issue on iOS7 with playing sounds, with latest iOS8 there is no such issue. Issue could be there if you trying on iOS7, I would suggest trying same epub on iOS8 and see if issue is there as well.
Thanks

Dodgy sound on iBook

Hi,
I have an iBook, and I have just noticed that when I'm playing music and DVD's through headphones the sound is really bad...echoey, mettalic and sometimes vocal is almost inaudible over the background music (on a dvd). I have used several different sets of headphones but it doesnt change it.
Sound through the internal speakers is fine however.
now, this may well be an issue with a dodgy connection in the audio jack, but just in case its a software issue (which, knowing these things it may well be) I thought I would post here before going elsewhere for repairs.
Thanks

I have the opposite problem. The internal speaker started to make a staticy chattering sound after using the new Superdrive to do backups. All works fine if I plug in headphones. We have had the beloved 12" iBook G4 open several times as we continue to upgrade it, so it may well be a wire that got roughed up. We've upgraded to the superdrive and are about to put in a new hard drive and more ram so the wire approach to troubleshooting the problem gives us a clue what to look for.
Thanks!

Popping sound on iBook in Tiger

Last week, I purchased a second-hand iBook G4 (1.42ghz, 1,5Gb of RAM). It came with OS X Tiger. I updated to X.4.11 but I got the problem that several Macbooks had as well : the popping sound from the speakers; every time I tried to increase or decrease the volume by using the function keys on the keyboard, I heard a strange 'popping' sound. Not a real problem, but annoying all the same. I had bought Leopard to install on my G5 iMac and thought I'd give Leopard a try on the iBook. It runs without problems, although I've got the impression it's not as reponsive as Tiger. However, the popping noise is gone. Now, I would prefer to reinstall Tiger as it runs more smoothly on the iBook, but I was wondering whether there is a solution to the popping sound problem in Tiger. Thx.

the popping sound from the speakers; every time I tried to increase or decrease the volume by using the function keys on the keyboard, I heard a strange 'popping' sound.
I think that that's the normal "signal" sound that you're changing the volume.
Mine does it too as have every iBook that I own/ed.
It was in Tiger and Panther.
This is from Mac Cast:
http://forum.maccast.com/index.php?showtopic=5068
"Go to your System Preferences>Sound>Sound Effects and uncheck the boxes located in the middle of the window as appropriate (viz. Play feedback when volume is changed)."
Too lazy to type it myself.

Sound problems, iBook g4

The sound output on my iBook G4 will change on its' own. Once or twice a week it will switch all output to my left speaker, and I have to go into system properties on my own and switch it back to center.

Hi Banihex and Welcome to Apple's Discussions.
Try Balanced. It is supposed to resolve such problems, although I have had no need to use it myself.

Sound input - iBook

Hey guys,
I'm on my way to convincing my mum to purchase a Mac computer. An iBook would be ideal, however she needs sound input so she can record things from a PA desk into garageband. I can do it on my iMac (my friend has done it before) and said I can, so I'm assuming I can. However it would be great for her, portability wise.
Is there an option/accessory/something that has audio in/line in or something like that which will help in this situation?
Thanks HEAPS guys
edit: This was posted in the iBook forum and they suggested I come here. There was an accessory posted from Griffin. http://www.griffintechnology.com/products/imic2/index.php - Have any of you had experience with using the iMic in the way that my mum is needing?
Thanks!
- leighton

The iMic is exactly what I was about to recommend (and then I saw your edit B-)>
The iMic is not going to be the highest quality, but for a few quid, it's a very good and inexpensive solution. I used one for about a year and was happy with it.
And BTW, we used it with mixing consoles on an iBook as well, so it should work for your Mum just fine.
Good luck! --HangTime [Will Compute for Food] B-|>

2 ibook g4s with dead backlights in 3 weeks

I have two non-warrantee covered ibook G4s which lost their backlights within just a few weeks. Video out to another monitor works fine on both. The apple certified repair shop found a burn mark on the motherboard, and the repair bill for each would be close to $400. I talked to a very nice supervisor at Apple, who denied that there was evidence of manufacturing defect and refused to offer extended coverage. Are others having similar problems? Any suggestions? Thank you.

Hi Jeff,
I am sorry for your troubles with your iBooks. That seems to be very unlikely that you have had such bad problems with your computer. Some things to think about for the future:
#1 I don't know if you did this, but buy AppleCare. It is worth it in the long run even if you don't have a problem. It is better safe then sorry.
#2 Becareful about how you handle your iBook/computer. I am sure you didn't do any damage to your computer, but just think about what could potentially happen. I don't have food or drinks ever near my computer, just incase. Buy as surge protector. It is only a couple of bucks at any electronics store and it is worth it.
#3 Clean your computer. If you notice a build up of "guck" around your computer get one of the little computer vacumes or CO2 canistor and clear it out. You want to make sure that everything is running right.
#4 Make sure that the computer's fan is not blocked by anything. The G4 runs hot so you don't want to block the fan from cooling it off. I use the iCurve in my dorm room because it lets cool air around the computer.
#5 Use your sences. Listen for any unusal sounds, like the fan comming on frequently. Notice if anything unusal is going on with your computer. Sometimes when the computer is beging to malfunction you can start to see changes in the way it opperates. If your computer feels extremely hot and is making noises, shut it off let it sit.
#6 When in doubt bring it to the nearest Apple Store, call Apple Support, or ask questions in the support forums. You can research by looking through past threads to see if your problem/question has been answered before. Things like over heating shouldn't happen to the computer, it was designed not too. But it happens.
I hope that helps,
Jon
PS It never hurts to write a letter to Apple. I had a problem with Honda and they didn't do anything until I wrote them a letter to the headquarters. We came to an agreement, both of us gave a little.
