New Powerbook Audio Stutter / Looping / Echo problem

I though people would like to hear the problem that some of the 15" and 17" powerbooks have been having.

I tried recording the sound from iTunes using Audio Hijack, but when the weird audio issue happened and I played back the recording, you couldn't hear it in the recording (i.e. it played normally), so it seems to me that it's related to some basic audio issue (because Audio Hijack couldn't hear it when it was recording iTunes) rather than a specific application.

I was able to record the sound using a cable from my powerbook to another computer (which then recorded the line-in using Audio Hijack).

Here's a short quicktime capture of the sound:

Has anyone heard anything about a fix? It doesn't seem to be related to Airport use for me since I don't often use Airport at home.

no mention of audio problem fix in the 10.4.5 update
have any of you installed the update yet ?

Feb 14, 2006 1:45 PM in response to aspenboy

Well, 10.4.5 is out.

10.4.5 web page says nothing about audio:

Give 10.4.5 a shot folks, but let's not give up if this isn't the fix we need.

He instalado el 10.4.5, llevo 30 minutos escuchando musica con Itunes y no aparecen Loops, I cross my fingers

Feb 14, 2006 3:15 PM in response to aspenboy

So far so good.

Installed the update and no stutters. Here is everything I'm running simultaneously.

iTunes playing
2 DJ Programs running but not playing music
Real playing Invader Zim
VLC playing Long Way Round
Adium running
DVD playing Appleseed
Quicktime running a looped music vid
Launched Classic

I even loaded up this big azz thread and no problems, although I never had it as bad as you guys.

Same here, HDD Sleep was turned off since day one, looping started on day two!

10.4.5 installing now, though http://powerbookdefect.info is reporting that it does not fix our problem 😟

As far as I am concerned this is the last chance saloon, if this bump fails to fix it then it's going back

No, but the tech doc does now say that upgrading to 10.4.5 is the solution to the stutter problem (go figure!):

6.4 MB OSX update?? Humm...No mention to the sound defect?? ...I'll keep my fingers crossed as well! It is either there and they are just not mentioning (no surprises here) or....well, we all shall see!

When you are running two or more audio applications on your PowerBook G4 (15-inch Double-Layer SD) or PowerBook G4 (17-inch Double-Layer SD), the audio may intermittently stutter, echo, or skip backwards. This can happen even if one audio application isn't playing or you have the sound muted in the application (such as when playing a game).

This can involve any application that uses audio, such as QuickTime, iTunes, iDVD, and many third-party applications like games and audio applications.

To avoid this, update your computer to Mac OS X 10.4.5.

this you can find in the KB

wow really nice communication strategy

Feb 14, 2006 3:43 PM in response to aspenboy

Remember Our KBase doc that used to say "Run one program at a time?"

http://docs.info.apple.com/article.html?artnum=302978

http://docs.info.apple.com/article.html?artnum=302978

http://docs.info.apple.com/article.html?artnum=302978

Now look at it!
It has been updated, changed to say "Install 10.4.5 to avoid this problem"

That's news my ears have been waiting to hear.

Cross your respective fingers guys.

Feb 14, 2006 3:47 PM in response to Rhagoletis pomonella

Your right. So I won't bother with this download then. I want to make sure it really fixes it.

Feb 14, 2006 3:49 PM in response to Graham Hancock

LOL... they won't publicy admit it, but will place it on the KBase, to avoid obvious embarassment. LOL.. Hey I'll take it. If it works, I think everyone here on this thread deserves a big thanks from me. Without your tenacity about this problem, I bet this solutions would have taken much longer.

Feb 14, 2006 4:00 PM in response to SuperSizeIt

from the software update is 6.4MB but from Apple web site is 14.6MB
Why?! Any reason for that?!
Thanks to all of you and for the guys who started this listing.
This chapter was a nightmare echoing on....
