Apple EarPods high pitched noise.

Whenever I use my Apple EarPods for phone calls, people on the other line are complaining that they hear a constant high pitched noise. What could be causing this? (Note: I just bought this pair 2 days ago.) Please help.

so bring them back.

To Apple Engineer. I hear a high pitch noise when surf flash-intesive sites

Hi. All.
I have a Aluminum PowerBook G4 1.25Ghz SD. I agree this is a great machine. It has a somewhat out-dated G4 Chip in it, I can do almost everything I need.
I've been using this powerbook for 2 years. Since sometime ago, I've heard very annoying "Hige Pitch Noise" from PowerBook. From further investigatin I found that this was a problem related to G4 CPU Processor throttling- so called "NAP" status. In Flash-intensive Web site, I clearly hear the noise.
According to solution suggested by talented apple user, I did followings.
1. Download or Install Developer Tools.
2. Download and Install CHUD tools from ftp://ftp.apple.com/developer/ToolC...ormancetools/
3. After installing chud tools, there maybe Processor pane in preference app.
4. In that processor pane, you should uncheck "Allow Nap" to reduce the notorius High Pitch Noise.(warning: it may increase the power consumption and temperature of CPU a bit, and of course you would see more frequent activities of CPU fan than before)
5. feel the silence.
To Apple.
I think this solution should be suggested from you not users.
Why we investigate, search the web for thosand of bucks PowerBook. Please fix this annoying(yes, annoying enough to cause headache) problem in next OS update.
To readers.
Sorry to my poor English(I live in Seoul, Korea)

EMac high pitched noise

Hi. I have a 1GHZ eMac G4 that I got second hand several months ago. Recently, I've noticed that there is a high pitch noise that it makes when I first turn it on or wake it from sleep. This noise only lasts for a minute or so, but it is very high in pitch. I don't think it is the hard drive because I know what a failing hard drive sounds like, but I can't be sure. Could it possibly be a capacitor problem? Does anyone know of this issue and how I could get it resolved? Thanks.

Anyone ever hear a loud high pitch noise

For the past week, I have heard a high pitched noise from my imac. It usually occurs when viewing videos and will go away once computer is shut off. It does ring when booting back up then goes away until a video or song is being played on the computer. Apple Support told me it wasn't something they could fix because the noise was heard during reboot. Any ideas? Thanks

Please describe "loud"... I hear once in a while a clicking noise that I know is coming from the hard drive while there is a lot of activity. It is noticeable, but I wouldn't say it's loud. My MacBook Pro does the same thing and at some point I was concerned but I found out that these noises are "normal" during a lot of disk activity.
I would still call or bring it to an Apple service store like the above suggestion, just in case! If you don't live near a store, maybe they will be willing to hear the noise over the phone? Just a thought.

High Pitched Noise When Recording From iSight Camera

I apologize if this has been asked before. I did a search on here as well as with Google.
Whenever I record a video clip using the built in iSight camera I notice that there is a constant high-pitched noise embedded in the clip. You don't hear the noise during recording, and otherwise the audio is crystal clear during playback, but I can't seem to figure out what is causing this noise. Video clips I import into iMovie don't have this problem. Has anyone else experienced this problem? How can I prevent this from happening with future recordings?

Hello obsidianspider
I am sorry to report that you are one of about ten people who have posted here about audio noises during video recordings with MacBooks. I listened to your YouTube clip, and I believe you are hearing something. I can hear the muffled "thumping" of background noises being amplified because there is no voice or other close sound being recorded in your video, but my old ears do not hear anything high pitched in your video (or anywhere else for that matter.)
I am sure Apple is aware of the issue, but with so small a number reporting this issue among thousands of MacBooks sold, I understand why there is not yet a kBase technical article on this subject.
I expect that Apple searches its warranty & repair work for quality issues and trends, but, if you have not (and do not) contact Apple or your retailer for service on this issue, please report your problem via MacBook Feedback so Apple can accurately record the magnitude of this problem. Unlike posting in this user forum, "Feedback" reports go directly to Apple.
We users who post here have found no solution yet, so the problem appears to require professional service for resolution.
However, if you are willing to try a test, please post back and tell us whether video or movie clip recording applications other than Apple's give the same audio noise you hear when using iSight with iMovie. Apple's QuickTime Pro has already been tested and found to exhibit the problem.
If you have access to an external microphone that can be located away from your Mac while you record video, you could also test to see whether you are recording a physical sound coming from your Mac or electronic noise being produced within your Mac's circuitry.
If you want to read the suggestions we have offered for minimizing your audio noise in video recordings, take a look at the suggestions offered in Eemma's thread, which was the first to report this problem. The suggestions for minimizing noise start here:

Airport Extreme - high pitched noise and no function

Hi all
My Airport extreme stopped working last night and just now emits a high pitched noise when the power is connected and there are no lights on the front (amber or green)
Has anyone else had this happen to them and is there any way to solve this without taking it back? Have only had this approximately 2 months.
Any help would be gratefully received!

Hi falloutphil,
When I bought my iMac, I had the store install more ram for me. It would restart all by itself. Then it would shut off. I can't remember a noise but after I was on the phone with apple tech, he wanted me to drop off the mac at a apple dealership. If you bought ram from someone else other than apple, it needs to be pushed in a little bit further. When you swing the two white thingys closed, push the ram in just a little bit. Before you do that, run the apple hardware test. I bought my iMac from JR's and when I reviewed the system log, the hardware test failed and they still sent it to me anyway. this just happened in July. My iMac has been running beautiful since then. but I will never buy anything from JR's store again.

A high pitched noise...

I've recently noticed that my 3rd Gen ipod is making a high pitched kind-of whizzing noise when it's in use. It started out doing it just when it was being updated so, I didn't think much of it. Now, it's doing it all of the time. It's never done this because so, I don't really know what to do about it.

I swear I'm not a dog but when using my Facebook app, my Yahoo IM app, and just having the home screen on, I get a very noticeable high pitched noise from the speakers. Tried a hard restart, still same thing. Goes away when screen goes to sleep, then comes back when back on after a minute.
Will bring it in, just wondering if I'm going to get the crazy look from the Genius at a noisy store who likely won't be able to hear....

Time Capsule has high pitch noise

I guess these things are notorious for their internal power supply failing. My time capsule started making a high pitch noise yesterday. Is this a sign of the power supply failing? Any idea of how much it would cost to repair? I have no applecare.

Welcome to the discussions!
Unfortunately, a high pitched squeal is almost always a sign of a power supply capacitor that is failing. Suggest you contact Apple to get the name of a nearby authorized Apple repair shop.
This link may also provide some help on repairs, although I cannot vouch for any of these shops.

High pitch noise when recording audio using internal mic

The issue I am having is with the internal mic. When recording audio using quicktime or garageband.It is a high pitch noise that stays whether i am speaking or not. The fix i found was to lower the input volume of the mic in system preferences. However, this causes my voice to be recorded so low that audio is barely usable unless volume is all the way up. Looking around the web I found this gem:
http://www.usingmac.com/2009/6/18/recording-speech-with-garageband-2009
This help me get rid of the high pitch noise for Garageband. The noise still there for Quicktime. Any ideas on how I can keep the same mic input volume with out having to listen to the high pitch noise?
Any help is appreciated.

Did you do the usual stuff, such as reset PRAM?
http://support.apple.com/kb/HT1379
There are some sound settings in PRAM, although I think it's only for sound output.
Also, as a test, I would create a new admin user account in System Preferences Accounts pane
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8235.html
Log out and log in to the new account (do not use Fast User Switching). In the new account, try recording something using QuickTime, and note if this problem recurs. If it does not, you have eliminated a few possible causes, such as a problem with the overall system installation or a hardware issue, and isolated the problem to something in your normal user account.

High pitched noise when recording w/ M-Audio Producer USB Microphone

hello,
I have an M-Audio Producer USB Microphone. Recording with GarageBand, nothing else connected, using an the Apple AC power cord (three pronged ground).
When I record with it plugged into the USB port closest to my FireWire port there is a constant high pitched noise.
When I record with it plugged into the USB port furthest from the FireWire port there is no noise at all (as it should be).
What's wrong with my USB port closest to the FireWire?

I am having major problems with iMovie (and iDVD) ever since I upgraded to OS.X.10.5.6. I had to scrap my last promo-video. I am now recreating it very gingerly saving as I go but I am now stuck again. I am getting the digital audio screeching under my video clips when I extract the audio and under insert titles and transitions. Does this describe your 'crickets'?
I have clean video and audio signal from my camcorder. Check your cam' playback to verify. After three attempts I do have clean material in iMovie but cannot proceed until I resolve this issue. I ruined my last video when I extracted the audio and ended up with a garbled rumble which I could not reverse.
I have another question elsewhere regarding burning to DVD but I now need to resolve this before I can get to test the recommendations in the reply.
I hope I have helped focus your symptoms. I also hope there is an answer out there for this issue.
BTW, Canon ZR-60 Firewire

Speakers Making High Pitched Noises!

Hey guys so I have my iPhone 5 for about 2 years in like 40 days (So I am still under warranty) Anyway I noticed when I play music, anything that is high pitched, it makes like a screeching or high pitched noise, I noticed my speakers were kind of dirty, so I took a fine tooth brush and got them squeaky clean and they still make the noise any reason why?
It's kind of frustrating, as when I play music it sounds like junk.

Hello, magoo657.
Thank you for visiting Apple Support Communities.
Here is an article I would recommend taking a look at. Try all of the steps in this article and if you are still experiencing the issue, see step 9.
iPhone: No sound or distorted sound from speaker

Time capsule makes high pitch noise then shuts down

Time capsule makes high pitches noise then shuts down

Unfortunately, this is the sound of the high voltage capacitors in the main power supply failing. It will not be long until the Time Capsule makes no sound.
If the Time Capsule in warranty, Apple will replace it. If you have AppleCare in effect on one of your Macs, the Time Capsule might be covered as well if it is not more than 3 years old.
Take the Time Capsule to an Apple Store....if you have one near you....to discuss your options.
Or, contact Apple Support directly.
http://www.apple.com/support/contact/
If the Time Capsule is out of warranty, Apple will not offer repairs, but there are some shops that will repair the device for you. See this link for more details:

Ipod touch 4 creates high pitch noise from cassette adapter

Did not have this issue with my ipod touch 2nd generation.
Have a Monster cassette adapter in my car (looks to be an earlier model than what is currently for sale at Apple website). ipod touch runs off of battery (not plugged into power source).
Creates a high pitch noise through the speakers. Not particularly loud, but annoying and very noticeable during quiet moments of music/podcasts
Volume of noise does not change with changing the volume on the car audio system.
Will start when the ipod touch starts playing. Will persist as long as the ipod is playing. Will not immediately stop when the music is paused. It will stop though after about 10-15 seconds.
Any ideas of what is causing this and why it did not happen with my previous ipod touch (2nd gen)?
Using iOS 4.1

Thanks for the suggestions/questions
If I plug the touch into my wife's car that uses a straight plug-in (no cassette adapter), I don't hear the noise. Unfortunately this is not an option on my car.
Have not tried plugging it into an actual home stereo but can give that a try.
If the engine is shut off, the noise is still present. Unaffected by the engine or RPM of it.
One other clarification - the noise is constant coming from the ipod. It does not vary based on the ipod volume. What this means is that if I turn up the ipod to full volume (and turn down the volume of the car stereo), the noise is less noticeable.
Of course the noise gets amplified with the rest of the music by the car stereo volume.
Will also try other suggestion and see what happens if I turn Airplane mode on.
Thanks

Unknown iMac High Pitched Noise

Hey,
My Grandma got an iMac (Intel C2D) and today it makes a high pitched noise. I am unsure where the noise is coming from in the machine.The noise happens all the time, and it even happens when it is off?
Is there something like a software update for this? or should we send it in for service?
Thanks,
- Devon Merner

Since you noted that the noise is present even when the Mac is off, it's probably emitted by the transformer in the power supply unit. It should be considered a hardware defect, though not a serious one but can still be annoying, it happens sometimes on electronics.
You can try reset SMU by shutting down the Mac, disconnect all cables and wait for at least 15 seconds, then reconnect cables and start. (http://docs.info.apple.com/article.html?artnum=303446)
And you can also try reset PRAM, though I doubt it's going to do anything, see
http://docs.info.apple.com/article.html?artnum=2238
if these doesn't work, you should call Applecare and make your case, if you can clearly reproduce the problem you shouldn't have a lot of trouble getting it serviced.

MacBook MagSafe Sizzling/High-Pitched noise

Hi everyone,
I just recently got this MacBook (Refurb'd) about 6 weeks ago and since then I have been noticing this noise that comes on once in a while when my macbook is on and is plugged into the MagSafe power adapter. It's sorta like a sizzling/squealing/buzzing/high pitched noise. It only comes on once in a while though - like it will stop after a while for like 5 seconds and come back.
Just wondering if it's normal - it doesn't sound normal to me....
Also, i'm in Canada - so there isn't a Mac Store nearby - any suggestions?

It's not normal. If there is no Apple Store nearby, there is still probably an Apple-authorized service provider - check the international Apple pages. Assuming something is wrong, they will exchange it for a new, non-sizzling one.
