Headphone noise / static / pops / digital squeaks

hi,

does anyone know what the bug report number is for this issue??

Well this is anoying...

Just got my MBP top of the line etc.. cost about 3 grand with college discount...

The mere fact that this happens on all of the lines of MB's is what concerns me...
None the less that at 3k nothing should be wrong. No problems should happen.

Even minor ones like these...

Besides the noise problem I love my mac! It just works, its small, light weight and never hangs up on me like windows used to do every so often.

I really hope apple will solve this problem or at least admit to it.

Maybe theres some route we can take to bring this to court? class action anyone?

As mentioned earlier, there is *still no software nor hardware fix* available. My personal research supports that statement. My Macbook Pro (early 2008) recently went trough a series of "repairs" and after two replaced audio cards, one motherboard and a whole new Macbook Pro (mid 2008) the problem was still the same: headphone noise, R2D2-sounds, interference with music, hisses and squaks; extremely irritating stuff, you know.

If you bought your machine from Apple Store and your warranty is still valid, I suggest contacting Apple Store and negotiating yourself a satisfying solution. After 4 months of frustration, repairs, returns and waiting, I admit that in the end a satisfying settlement was found between me and Apple. I'm happy that at Apple they were understanding and fair. If you act politely and pertinently while solving the problem I think there is no need to sue anybody for this issue.

Yes I did notice the same problem with sound using my Tascam 144. I bought a used macbook pro that was babied and in great condition. I installed Logic Pro Studio and everything was bliss for a month. One day I tried to play a Logic Song that had been working perfectly and I started getting all these error messages, amd just wouldn't play. I would have thought it was overloading the CPU (which is what the message said, but I had gotten it to play perfectly the day before..... I even resaved it and then started deleting tracks to see if I lightened things up what would happen. I got down to THREE tracks from 15 and still got the error messages. I tried a different song and the it played but the sound kept crapping out. I thought it was the Tascam so I tried the internal sound and got the same thing: sound crapping out. I thought it was Logic because it came on the heels of all these system overload messages that I got in a song that had previously handled the cpu load just fine. I reloaded Logic. Still got the problem. I tested the hardware using the disc and holding down D. Got error message 4SNS/1/40000000:TBOT. Checked a few online forums and found.... possible motherboard problem, power supply problem, overheating problem, HD problem.... and those threads didn't even talk about 'sound' issues, I just typed in the error code. I know that there are musicians who rely on these machines and they work for them..... I have yet to get one to consistently work, and I have spent a tone of money in the last 10 years. I had a G4 literally melt down and have to be replaced after 7 WEEKS of testing at apple...... and it had worked erratically before it melted down so I literally spent a year and a half getting no work done (I thought the problems were user error because I was a novice mac user, it wasn't until the hardware started to die that I realized what was going on.... nightmare). After the replacement, in fairness it became quite a workhorse and I still use it for certain things, but it did have to be replaced. A month ago the mother board on my G5 just bought the farm.... which is why I bought the macbook pro. Maybe I'm off topic here but my machine is not under warranty. I just want it to work. And I can't see how so many issues could be involved. I have been a loyal Logic/Mac user for years...... I just don't get it. Just want to have some consistency and value for the money and time I've put in learning the software and TROUBLESHOOTING.

So to re-answer the question after the above tangent, yes, I have had the same problem with sound using an audio interface. Never tried the closing the lid thing. At this point I'll try anything..... except forking out a bunch more money!!

I bought my Macbook Pro 17" in June 2008, and returned it twice for related sound card troubles, before keeping the third one (that seemed to have a less noticeable speaker "pop" when the sound card woke up). It was a while before I noticed that the headphone out line was producing R2D2 bleeps and bloops and intermittent whines (should have thought to bring headphones to the Apple store). Now I'm wondering whether it will be worth the hassle to return it for repairs (since I'm well outside the two-week exchange window), or if I should just continue to suffer with defective Apple hardware (which appears to be endemic) and never use headphones. Maybe the other people on the plane will also want to watch Wall*E, after all.

I am happy to hear that you achieved a satisfactory resolution to this problem. I have made an appointment with the genius bar at my local Apple Store for this Saturday, and have included a link to this post in my reservation. Hopefully they can fix the audio output without keeping my computer for too long!

I bought my MBP in June 2008 as well. I make my living in pro audio as a sound designer and I'm usually using an external card as opposed to the Mac headphone output, so this isn't that much of a problem for me. I can verify, however, that using either a Firewire or USB card eliminates these noises (as long as you don't plug anything back into the Mac headphone jack). I'm wondering if the circuitry concerned with the headphone output isn't balanced properly, which could explain how interference audibly makes it's way onto your headphones or speakers.

Between this and the NVidia chip issues on my nearly 3k machine, I'm about ready to raise **** with AppleCare, only I don't have the time to deal with the issue 😟

So i was having the same problem, turns out i was getting feedback from a lessthan par HDD enclosure i had purchased... before complaining about apple make sure nothing but the speakers and the power are plugged into the computer... Apple can't do anything about devices throwing electric feedback back at your computer
