I think we need to clarify the audio faults. I currently have 3 audio problems.

1/ Occasionally I get an echo-like looping fault.

2/ I regularly get a break up, similar to a CD skipping, up to a quarter of a second of silence, then the sound continues.

3/ Plugging in headphones whilst recording, causes the loss of about half a second of the recording.

Can we call these ...

1 = Echo or looping
2 = Stutter or skipping
3 = Jacking loss

Please reply with which of these faults you are suffering. Also please reply if you have no audio faults, so I can get an idea of how many are affected.

    1: Echo and looping
  • Chris Marks Level 1 Level 1 (20 points)
    #1 on a 15" Hi-Res Powerbook. Seems to happen more since 10.4.4 update.

    I use the computer for web development and graphic design

    1: [looping delay] sometimes very frequently, as much as every 5 mins. However it has disappeared for a number of days before, but always returns, even after 10.4.4

    Haven't experienced the other two although i've had some weird loud feedback noises on interface sound effects, eg. the 'poof' when removing items from the dock or toolbars sometimes comes out like an office buzzer/static sound. Most strange, have witnessed about 3 times now in 6 weeks.

    I don't know if it's related [perhaps dodgy logic board] but my display drivers default to 'generic rgb' profile when i 'fast user switch' and wont allow anything else unless i reboot.

    All my issues haven't changed with zero-ed data clean installs, cache cleaning, PRAM etc

    1 and possibly 2. I get the echoes for sure. Might have noted some skipping, but it's much more rare for me.
    I haven't done any recording of sound.

    I get 1, 2, and 3....
    I got the new PB because the Optical Digital audio in. Fortunately, the problem does not seem to affect the Optical audio inputs. I was waiting for 10.4.4 to see if these issues would be fixed. They would not so I will make the call n the morning.

    Problem #1 on my new 15" Powerbook
  • Ian Hobson Level 2 Level 2 (485 points)
    Definitely #1 on my Hi-res 15" PB, and a variation on 3 - I get a temporary hang for a second or two on removing the headphones.

    I have only experienced the problem using iChat audio and Skype. In both of these it has happened multiple times and makes it sort of unusable for such purposes. I have never had it happen in iTunes or DVD player for instance.

    I have taken it into the London Regent St. Apple Store today and talked to a genius. They have NO reports of such problems, and although I was able to show the KB article and these discussions, the response is that if there is a problem, it's still unknown as to the cause. My choice is to leave it in with them to reproduce it and then to do what they need to fix.

    I'm a bit reluctant to do that as I don't want to be without my machine for too long, and I also figure out surely someone somewhere really will confirm the cause specifically and allow us to all apply directly to get a fix (which in my experience should only take a few days).

    1 and 2... I haven't tried 3 so I don't know.

    It's getting worse and worse. It does seem to be worse when the processor is being used more extensively.

    trx bloke - please could you send me some information on uk consumer law regarding getting a refund? I spoke to the reseller and they say that they can't do returns - that's apple's domain. I have the sound problem and can't do production/live performance with it.

    Can you (as you said you were willing) detail what law requires of them so I can take it to them?

    Does the fact that I got the pb on finance affect this? Can I demand a refund and not just a repair?

    Thanks. Your help is much appreciated

    Reach me at

    I get 1,2,3 btw

    UK law...

    Under the Sale of Goods act 1979 (amended),

    "Goods Must: Fit the description given; Be of satisfactory quality; Be fit for their purpose; If not the retailer is legally obliged to remedy the problem."

    Your contract is with the shop where you bought it, not with Apple.

    Simply hand the goods back to them, saying that you reject the goods, and wish to have a refund. Ask to speak to the manager, and use the words "Sale of Goods Act 1979 Amended" and "Breach of Consumer rights" This usually does the trick.

    Also quote the Sale and Supply of Goods to Consumers Regulations 2002, which states that you have the legal right to...
    "choose repair, replacement, partial or full refund, or compensation if a fault appears within 6 years, if it is reasonable for goods to last that long."

    If the shop refuses, contact your local trading standards officer (take the number with you and dial it in the shop)tell them that the shop is refusing your request for a refund on faulty goods.

    Many shops are ignorant of the law, many ignore it. Many will try to tell you its Apples problem (it isnt). At the end of the day they just dont want to give you your money back. Good retailers dont argue, they just give you a refund. They know the value of repeat custom. I have never been back to places where I have had to argue my point. They have lost thousands in lost custom from me.

    Sometimes you will have to stand your ground, and speak to managers etc.. Of course this should be done in front of all the other customers (not good for business). Sometimes you will have to walk away and send a Solicitors letter.

    It may be that you have to take them to court, but you do NOT have to accept faulty goods, none of us do.

    As you bought the computer on a credit agreement, then the finance company is equally liable for the cost of the goods. You can sue them too if you have to. You could contact the credit firm and let them know the situation, and tell them that they are equally liable under consumer law for the condition and suitability of the goods

    Have a look at and perhaps the "which" website.

    If you are a member of which legal services then contact them. You may have legal advice with your house insurance.

    Dont give up. I once had a Fujitsu Laptop which crashed every time I plugged a USB device into it. It was a design flaw causing a bus undervolt when USB powered devices were plugged in, but the shop claimed it as a characteristic of that model. A year later I got a refund of the full amount as I had no significant use from it. I used the money towards my first G3 PowerBook.

    I have never been unsuccessful in a claim for a refund. But then the goods have always been imperfect, and the law has always been on my side. Sometimes though you just have to be patient.

    Does anyone know about the Dutch Law?
    Thank you very much in advance.

    In my brand-new PowerbookI get the same echo-like looping fault when every I use any program or device that provides audio output: iTunes, web-page broadcasts, realplayer, radioSHARK. Have tried to using only one audio program as recommended by the Apple Knowledge Base, but no joy. Am calling Apple Care today.

    Just got off the phone with Apple Care. The person who took my call said that she was unaware that this echoing problem existed with this model. I gave her the reference to this thread, which she read, and then said she would pass the report over to engineering. Other than having me bring my 'Book into an Apple Store for examination, she didn't have any other recommendation for a fix. But she did say these discussion boards were monitored (smile).
