Macbook Retina cracking sound when muted

Hey guys,
I just found that my Macbook Pro with Retina display makes a litle cracking sound when trying to play an alert, even when muted.
Not sure if it's an issue or a normal behaviour.
You can check if yours makes this as well when turn off the sound and make your mac play an alert sound, e.g. go to System preferences and press cmd+j (this is an invalid shortkey that's why it will try to play an alert sound). The cracking sound is not really loud so listen carefully.
Please let me know how it went.
The local AppleStore is really far away from me so I don't want to lose a day for invalid issue, that's why I need your help.
Thank you!

just an update... a few hours later... my backlit keyboard refuses to light up.. what the heck?
Time to Return it for a new, properly working, MBP.
And as to the Tech guy saying "This is a New Problem", "Never Heard of it Before". That is what they always say even if it has been reported Thousands of times and written about in printed and On Line Mags.
Only after Apple has made a publix ackownledgement of the problem, and plan on trying to fix it (which sometimes they never plan on fixing a problem and never make a public acknowledgement) will the phone techs say "Ok yes we know about it".

Macbook lid cracking sound

I bought my brand new macbook on saturday and it has been making a cracking sound when opening the lid, sometimes really loud and sometimes quietly. Every time i open the lid i can feel the lid catching on something but can't see anything catching. When looking at the macbook the hinge seems to be further over to the right than the left.
Is this normal or is there any way to fix it or should i just take it back?
Thanks

It is not normal and it is rare. Take it back.

Might be corruped sound preferences ..
Type or copy paste the following;
/Library/Preferences/Audio
Click Go the move both .plist files from the Audio folder to the Trash.
com.apple.audioDeviceSettings.pllist
com.apple.audio.SystemSettings.plist
Restart your Mac. See if that made a difference ...

NEW MacBook Pro Retina cracking sound problem

I recently bought a MacBook Pro Retina after using a MacBook Pro for a year. From Day One my MacBook Pro Retina makes a cracking sound from the body on the right side. not acceptable from such a expensive machine. Apple would not replace it! Now I don't know what to expect, but I never expected this. Laptops worth 400bucks are not this cracky. After browsing through i see im not the only one with this problem. The local apple service center said they have checked it everything is fine and it is not damaged, it was a manufacturers defect. Why should I be the victim here?

Resetting the NVRAM/PRAM didn't work. The crackling sound is especially bad around the 4:00 mark in the following Killzone Shadow Fall preview:
http://www.engadget.com/2013/02/20/watch-the-ps4s-killzone-shadow-fall-shared-di rect-from-the-con/
Several songs in the iTunes store, when previewing, also have the same crackling issue.
I'm just glad it's not crackling for every single video or song, at the very least.

What is the cracking sound when I open my MacBook Pro lid?

When opening and closing MacBook Pro lid, it makes a cracking sound. Does anyone have an idea what it could be? It's not the hard drive because Geek Squad ran a test and everything passed.

Try this: Loosen the screws in the rear of the MBP (by the hinge) and re-torque them. See if that will alleviate the problem. You will need a 00 Philips driver.
Ciao.

Macbook Retina Display - Creaks when opening programs

My macbook retina display creaks randomly only when programs open.
For example, when diablo opens, it makes a creaking sound just underneath the keyboard.
When a youtube video starts playing, it creaks.
When i open chrome or safari, it creaks.
It only creaks at the beginning when programs starts running.
Wierd.
anyone having this problem too?
Please share.
cheers.

I imagine it is not an expected issue, as my 2010 MBP worked just fine. Also, were the issue expected I would hope that it would be compensated for. I am typing this response on the Retina MBP and there is definitely lag or letters disappearing all togther. I am also typing this to get the screen shots of the activity monitor.
Here are the results:
Also, when posting the pictures here in this message, the images seemed askew until I scrolled the screen a little. It would seem to me a video card issue but I am not a Mac genius so I am just guessing. I am using the default "best for retina" resolution setting.
This is also what I am saw just now as I was scrolling:

Iphone 4 cracking sound when calling someone.

History - I've been having issues with iPhone4 ever since I got it on the 24th june. First the visual voice mail didn't work for the longest time. I did everything apple and at&t asked me to do and reset the phone and network settings. Finally I had to reset it as a new phone and couldn't use any back up. I did this a week back.
I answered a call today afternoon and there was a cracking sound. The other person couldn't hear me and i couldn't hear them. I restarted my phone twice and I could hear them clearly. But they still couldn't hear me. I tried using earphones and the mic and they still couldn't hear me. My mic works fine since I can record just perfect and when I connect the earphones I can listen to music and hear the typing as well. Everything except when I call someone. Sometimes after restarting my phone it works. (like once in 5 times).
WHAT DO I DO
I realized I hadn't answered any calls for 40 hrs. And I'm pretty sure I didn't drop it. Plus it is well protected with a case. But I'm still pretty sure I didn't drop it.
Any suggestions ??
It has 4.1 installed.

Do you know what might be the reason ?
cuz somehow they always have reasons why not to replace it n' why it's not in warranty anymore

MacBook making clicking sound when moved?! not the sms HELPP

Today, i was using my MacBook and it started to make a clicking like sound when moved from side to side. I have had my MacBook for less then a week so I have no idea what could have happened. The computer has not beed dropped or anything! It is not the sms because I turned it off to see if the noise would still happen, and it did. Also this happenes when the computer is off. I cannot take it to a store because the closest one to me is an hour away.

Normally, a clicking sound would be an indication of a bad HD or if the Superdrive is trying to read a damage disc. Personally, since its a week-old computer, I'd take a one hour drive than taking the chance of the HD failing after the warranty expired. You can try calling Apple as well (1800APPL). You should still have FREE phone support.

NO SOUND WHEN TOUCHING CLICKWHEEL, CRACKLY SOUND WHEN RUBBING FACEPLATE

Hello, I have a 30Gb iPod video and the sound isn't working. If I turn it on and play a song, I get no sound. The screen shows the song and if I adjust the volume via the clickwheel, the volume bar moves up or down but still no sound. *However, if I rub the face of the iPod with my thumb, I get sporadic, crackly sound.* (?) Anyone know what's wrong? I've already replaced the headphone jack and also swapped head phones.

Hi
I have the same problem. iPhone 4S with newest update. No sound while playing music (grey volume buttons). No sound for alerts e.g. incoming SMS.
Total reset does not help. Restore from iTunes Backup helps, but sound only available for some minutes (can play music direct form iPhone, without ear-phone)
Issues is still open. All contact cleaned (ear-phone etc.)
Please help.
With kind regards,
Swiss JFK

Macbook Pro Retina - Weird sound when plug in adaptor

Hi,
I have had my Macbook Pro Retina 15inch now for about a year and a half and suddenly it's making a sound whenever I plug it in. It's like the sound of a hard drive, but it's in sync with when I scroll up and down. There's no sound whenever it's unplugged, it's very strange. Any ideas, could it be a faulty adaptor?
Thanks
Lewis

It is better to take the computer to the Apple store and have it checked out.
If this does not help, contact Apple.

My retina iPad make a cracking sound when you press slightly in the area around the front cam. sounds like scotch tape that doesn't stick properly. Anyone having that too?

Ì fear that the cover will crack open over time.

Well I bought it 3 weeks ago, looks like I need to visit the store where it is from. Unfortunately there is no apple store in Vienna Austria yet
thx

Why does my MacBook Pro make sounds when I put it in my bag?

I am a first time Mac user and have only had my MacBook Pro for a few weeks. When I put it my back to carry with me to work, it makes a sound like something is running even though I have shut it down. Can anyone help me, I dont want to mess up a great laptop.

I'd make a sound too if i was put into a bag haha.
Only thing i could think of it it has a mind of its own or your putting your computer to sleep. Try shutting down your mac before placing in your bag and see if that changes things.

Cracking Sound when Copying Music -- then Freezes

Has anyone ever experienced a crackling sound as the iPod is copying music? When this happens, iTunes freezes as well as the iPod.
It has happened on a few computers with this iPod, so it most likely isn't an issue with the computer.
Anyone else had this problem? Is my iPod defective?

Hello JonathonMaurel. I understand the sound on your notebook is cracking/buzzing.
Does this issue persist if you use external sound devices (such as hooking your notebook up to a TV via HDMI) or headphones?
How long has the issue been occurring?
Does the cracking/buzzing stay the same when you increase/decrease the volume?
You said that you have the latest drivers installed but have you tried removing them and allowing Windows to install the driver? This resolves a large majority of issues for users. Try the following.
Click Start, type "Device Manager," and press Enter.
Expand the Sound, video, and game controller section.
Right click on your sound device and select "Uninstall." You should remove the driver only, if prompted.
Reboot your notebook. Once Windows loads it will attempt to reinstall the driver.
Verify whether the problem is resolved and post the result.
If this doesn't resolve the issue I am going to need a little more information to help me identify your specific notebook to look deeper into the issue. I can easily identify your notebook by product number if you could provide that. This document can show you where it is located.

Macbook Pro cracking sound on Vista x86

Hello,
In run Mac OS X 10.5.6 and Vista Business x86 via Bootcamp. However, the sound output while running Vista is cracking and slightly hissing every ~20 seconds.
Does anybody know the correct sound settings of the internal sound card (e.g. 24-Bit/48000HZ) is? Or is it just an unresolved sound driver issue?
Greetings
Thomas

I just found out that the sound chip is a Realtek ALC885.
Chip Specs here:
http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PFid=28&Level=5&Co nn=4&ProdID=138
Regarding the sound sound settings, there is a Realtek Audio Manager accessible through Start>Control Panel>Realtek HD Audio Manager.
What worked for me, was, I set the Default Format in Start>Control Panel>Sound>Speaker Properties>Default Format to the same setting as in the Realtek Audio Manager and I also deactivated the "Exclusive Mode" in said window.
