Macbook Alu high pitch in windows

hello any have a solution for this problem when i have the brighteness at 50% the mac do a high pitch. does any have this problem? and a solution?

I believe there is a driver issue when running windows and getting the high pitched noise from the display (it goes away when you turn the brightness up/down, right?)
There have been quite a few discussions on this already...try searching the apple discussion board for more information

Since Yosemite upgrade, high pitch noise creating case vibration on MacBook Pro (15-inch, Mid 2009) (on watching the keynote online)

Hi,
Great work on Yosemite, great new design as well.
Several problems since the Yosemite upgrade though :
    - When playing high pitch noise (watching the keynote for example), the speakers make the case around it vibrate. This was not happening under Mavericks and previous OSXs.
    - This page (post editing) does not allow the right click (works everywhere else as far as I'm aware).
    - when changing the volume, I have now the noise feedback when clicking on shift+volume up/down and no sound when clicking on volume up/down on my keyboard (was the inverse before).
    - The keyboard light was stuck in off, had to restart the computer.
More general problems (covering the last OSX since introduction of 10.9) :
    - lack of possibility of choosing for a 3x3 set of desktops as it was before (the new mission control only allow us to have a horizontal set of several desktops)
    - Notifications cannot be turned off automatically when being in full screen. (only options for auto turn off given are "display is sleeping" oO and when "mirroring on another display" -> meh, would have prefer when having an app in full screen)
System :
MacBook Pro (15-inch, Mid 2009)
Model Identifier: MacBookPro5,3
Processor Name: Intel Core 2 Duo
Processor Speed: 2.66 GHz
Memory: 8 GB
Bus Speed: 1.07 GHz
Boot ROM Version: MBP53.00AC.B03
SMC Version (system): 1.48f2

Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

Macbook Pro and high-pitch sound, please help!

Hello,
     I have a Macbook Pro 13 inch that is almost brand new. I just got it 3 months ago for my birthday. About a month or two with my new computer I started hearing a high-pitch sound comming from the computer. The sound only lasts about 3-6 seconds and it goes of at random times. It might make the noise 5 times in one day but then it might go away for 3 days, totally random. The sound comes if the computer is sitting there or is being used. After about 3 months of this going off I deceided to bring it to the Apple store in New Haven, CT. Does anyone have the same problem?
     After bringing my computer in and telling them the problem, they tested in for about 30 minutes. Everything was fine. No fan problem or hardrive problem. I brought the computer back home and within 3 days the sound is back. I drove to the Apple store again told them my problem,again, and they did they same test with no results. Brought it back home, noise is still there. This time im starting to get angry, they arent offering any solution. I bring it back and they take it for about 48 hours and do a extensive check. Nothing was found. I bring it home again and the noise is still there. My father and I went to Apple pretty angry and told them that we appreciate the time they take but something really needs to be done. They have sent it out for 3-5 days and we are awating a phone call to see whats wrong.
     I am hoping that they find something or if they dont can they can replace my computer? I am not spending hours of my own time and gas money going back and forth to Apple for no reason..the Genius bar guys have been no help telling us basically that we are lying and that there is nothing wrong when clearly there is. What can I do? Has anyone had this same noise come from their computer? I really appreciat everyone that decideds to throw some input in. Thank you so much.

I have the latest software

Make a recording of the sound so the next time you take it in you can let them hear it. It might be best to do a video of the unit so the sound is combined with pictures/video of the computer so they know the sound is coming from it.
IMHO the guys at the B-bars are just about useless for this type of thing. If it isn't a bad drive, HDD or DVD, and the system seems to run OK (actually even if it doesn't run OK but runs at all) they will say "Everything looks OK". Or if the thing is dead they can help. That help will be "You need a new HDD" "You need a new DVD drive" "You need a new Logic board" and that's about it.

MacBook gives 2 high-pitched beeps at 7am

Don't have any scheduled events at this time, but the MacBook gives these two high-pitched beeps at around 7am on most (not all) days. Even does it when asleep. The beeps do not appear to be coming from the speakers and they're unlike any system sound, so is there something on the motherboard or in the drives that could do this? Is it a warning of impending failure?

Suspected that but how to diagnose what the problem is? System Profiler reports that the RAM (2 x 1GB Kingston) is OK and Disk Utility 'Verify Disk' returns 'appears to be OK'.

MacBook Pro Retina making a high pitched whine?

So 2 weeks ago I bought a 13" MacBook Pro Retina. I noticed a high pitched squealing noise coming from the rear left of the laptop (around the 'esc' key). It's definitely not the fan. The noise stops almost immediately after putting the computer to sleep. Messing with the brightness of the display/keyboard changes nothing, nor does messing with the sound volume. Just wondering if it is something to worry about...paying $1,200 for a faulty machine is quite sickening...haha.
Also, on two occasions I noticed a clicking sound coming from what seemed to be the right speaker. I don't know if that could be related.
Thanks!

i actually have the same problem but dont know how to fix it
its annoying.

X-Fi Titanium PCI-e making high pitch squeal on Windows 7 with HPET enabled

Two days ago, I tested an older Radeon 4800 to see if it still worked. Long story short, some how I screwed up my integrated sound (Realtek). I reinstalled Windows last night, and after several hours of hair pulling, still wasn't able to get it to properly play sound at all. I disabled the on board audio in the BIOS, installed my X-Fi Titanium Fatal1ty Professional PCI-e I had sitting around, and finally had sound working again (through the X-Fi). Sound was fine using the default Windows drivers, however after installing the Creative drivers, it's constantly making a very high pitched squeal. The squeal doesn't change at all, and it's constant, if I had to guess I would say it's at the very or near the very end of my audible hearing. This was the same story when I first installed the X-Fi card when I first built the computer one and half years ago, which I eventually removed a few weeks later to simplify my build and stuck with the on board audio. Back then, I figured out a way to get rid and it involved disabling the High Precision Event Timer (HPET) in the BIOS. I did the same today and it removed the squeal, but I'm wondering if there's any way of getting rid of the squeal without disabling the HPET. What confuses me is why the Windows sound driver didn't squeal but the Creative one did. Windows 7 is fully up to date, as are the drivers.

When installing the Dolby and DTS connect packages, you need to right click each and choose to install them in VISTA compatibility mode. Then they install just fine.
As far as your driver issue.........
do a search for DRIVER SWEEPER from guru3d and that will uninstall your driver and hopefully put you back to a good reinstall. Also inside your driver folder you can look for utility called CTZapp that will uninstall all traces of that driver so that you can reinstall it properly.

Does anyone know why my MacBook has an intermittent high-pitched whine?

Today my MacBook started making a high-pitched whine. It's like a high musical note and comes and goes. I closed as many programs as I could. Still working in Chrome (and that's what I have been on when it makes noise). It almost reminds me of a fanbelt issue.... but that's impossible, right?

Yeah, if you go to Programs > Utilities > Audio MIDI Setup
Then select where you want the sound to come from, then click on the settings cog at the bottom, and select Use this device for Sound Output, and you can select the internal speakers for System Alerts & Sound Effects if you wish.

High pitched squeal noise and low end rumble RME Fireface 800 Macbook pro 2011

Hi there,
I just updated Mac OSX Snow Leopard and my Fireface 800 has started emitting a high pitched squealing noise when turned on and connected via Firewire 800 cable.
Also my 17" Macbook pro requested a hard reset last week for the first time, after this problem began.
When my subwoofer is connected, a low end rumble is emitted at the same time as the squeal, and persists until turned off and on again.
Any ideas?
Thanks
Robin

High Pitched Whining Sound from Macbook

We bought the new 13" Aluminum Macbook today. In getting it set up there have been some periodic times where it started making a very high pitched whining sound that I could hear but my wife could not.
The ability to hear these high end sounds go away as you get older.
Just wondering if this will need to be repaired / returned ? What do we do. I can't stand it!!

Phil is right of course. You should send/take it back and get a new one.
Is the whine coming from the hard drive?
With the easy to replace hard drive in the new MacBook you can easily swap out the hard drive in your current unit with the new unit. That saves you reinstalling programs and transferring data. However with a whine I would be leery about keeping the same hard drive.

Do your MacBook make a high pitch beeping sound?

Just got a late 2011 MacBook pro with SSD hard drive (17 inch i7).
I have noticed an almost inaudiable high pitch 'morse code' like beeping coming from the machine. Maybe the SSD being accessed?
I do have tinnitus and have been known to become irritated from low Hz monitors and TVs in the days when they operated at 50-60 Hz. So maybe something in the machine is operating at that fequency.
It may be nearly audible, but it's driving me mad when the music is off and I'm trying to concentrate!
Does anyone else experience this?

Does the beep sound similar to this video? Skip to the 00:44 mark to hear the sound. If the sound is this one that means that your Mac is trying to update its EFI.
Would you mind recording a soundbyte? That could be really helpful. It's not possible that the sound is coming from the SSD, perhaps is your fans.
Hope that helps.
P.S. If you are too bothered you can also make an appointment at your local Apple Store Genius Bar.

New Aluminium MACBOOK - Airport Extreme adapter very high pitch scream! Oww

I have just connected my Netgear Wi Fi router to my PCin order to get the internet on my Brand new MACBOOK. Unbelieveably I found this very easy once I had the necessary kit but to my dismay the Airport Extreme adapter on the the MACBOOK has started to scream at me in a way that is almost unbearable to listen to. The noise is that of a sinclaire spectrum loading but at a very high pitch so it pierces the ear drum! I am currently sitting with my finger in one ear to try to protect my brain from the savagery. Does anyone else have the same problem? none of my other Wi Fi adapters sound like this, is there anything I can do to stop this?
Please Help

If anyone's interested, this seemed to have to do with WPA-PSK encryption. Turning it off seemed to work. Don't want to run unencrypted, so I'm using the Netgear USB dongle thingie instead of the airport card for now.

buckmacie,
has the video been completely downloaded onto your MacBook Pro when you start to play it? Or are you playing it while it downloads, AKA streaming it?

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.

High Latency in Windows 7 64Bit on MacBook Air 2010 NVIDIA with DPC Software

High latency in Windows 7 that is interrupting sound on BootCamp partition with NVIDIA Drivers
3000us all the time
I can't use my interface with it.
Anybody know how to fix it?

Thanks for posting the pictures...it makes it much easier to see what's going on.
First off, use the proper Focusrite ASIO driver, not ASIO4ALL. Make sure you have the latest driver installed, available here: Downloads | Focusrite
Then, on the screen shown in your first picture, use the slider on the Focusrite control panel to change the Buffer length to the lowest setting at which you can get reliable recording and playback. It's currently set to 10ms which is 480 samples (as shown in the Audition Preferences/Audio Hardware panel. I tend to use 128 samples which is between 2 and 3 ms but exactly what works for you will depend on all sorts of factors. Some people like to use a low setting for recording and the highest possible setting when mixing a multitrack session.
Finally, for pretty much all recording, I'd recommend the use of the Direct Monitoring feature on the 2i2 rather than trying to monitor via a round trip.

I have a very high pitched constant sound coming through my monitors when my iMac 2013 is plugs into my audio interface (Komplete Audio 6) this doesn't happen with when using the same set up but with my macbook powering the interface

Hi i was wondering if anyone could help me out with regards to this high pitched noise- i am assuming its coming from the imac as when i swap that with my laptop in the exact same setup all high pitched noises are gone.
Any help would be greatfully appreciated its actually driving me a bit mad now
Thanks
Kash

Have you tried a PRAM reset?
