Sound, sometimes a sizzle, simetimes a high pitch from under the "tab" key

I am mainly just curious here. I would like to know the sound is that comes from under the "tab" and "caps lock" keys. It can be a constant ptich or sometimes of a fuzz/sizzle/static quality.
Most of the time the high ptich will be present with micro-second spaces of silence ever 1 or 2 seconds. Then after a while the pitch will cut out leaving the staticy sound.
The sound is not really that bothersome in a totaly silent room but I would like to know what part of my MB makes this sound anyway.

I also have this problem, except I find it extrememly annoying, I only noticed it a few days ago.
Remember the whining issues with the MBPs? One of the workarounds was to engage the built in camera in some way. Opening photobooth stops the sound. Which means it obviously isn't a nesacity.
I am going to need to phone up apple support. This MacBook has been nothing but trouble for me.

On Mac, need to navigate to first google search listing by keystroke, the tab key works sometimesand sometimes the down arrow works, nothing works consistently

If I do a search using the google search engine, say of a phone number like (530) 335-5414 it results in a page with about 10 to 15 listing. Here is what the page looks like
https://www.google.com/?gws_rd=ssl#q=%28530%29%20335-5414
I am on a mac and I need to find a keyboard command to get me reliably to select the first listing . When the caret appears next to the listing I can press the enter key to open the underlying hyperlink.
I have had success doing this with the tab key and sometimes it works almost 8 times in a row. Then I sometimes use the down arrow key and it occasionally gets me there. IS THERE A RELIABLE KEYBOARD NAVIGATION TO THE FIRST LISTING ON A GOOGLE SEARCH RESULT PAGE. I don't understand why my keyboard only works occasionally to navigate in this way . This is very important for me to do this and maybe someone out there knows how to get to select the first listing on a page by keyboard that works.
Thank you very much for you

I've called the big guys to help you. Good luck.

[MSI 760GM-P23 (FX)]High Pitched Noise near the CPU or from the CPU itself?

I just built this rig 3 weeks ago and I decided to update my BIOS because it's not compatible with Spec Ops: The Line, the game worked but the mobo/cpu started making these high pitched noise. I'm pretty sure it's not coming from the PSU because it at the bottom. The sound is not consistent
but it's really annoying when I hear it, do I need replace it or is there a way to get rid of it?
Specs:
AMD FX-6 6100 Black Edition 6 Core 3.3Ghz
MSI 760GM-P23 (FX)
Arctic Cooling Freezer 7 Pro rev 2
Crucial 8GB (2x4GB) DDR3 1333Mhz Ballistix Sport
PowerColor HD 7770 GHz Edition 1GB GDDR
Samsung HD103SJ Spinpoint F3 1TB Hard Drive SATAII
CIT 500w Power supply

In most cases such noises are the effect of resonance caused by a PSU that does not provide clean power (not able to properly filter the noise in the signals, especially under rapidly changing power demand conditions).

Is the Azure Files data highly available/replicated under the covers?

I am assuming that with Azure Files, under the covers data is replicated multiple times for High Availability. Is that correct? For some applications, typically failover application, where the application doesn't assume highly available storage;
the applications themselves build logic to either replicate/sync data. An example is Elastic Search. In these cases, the system lands up making too many copies. Is the Azure File Semantic the same as blob store, in this regard.

My iPod touch (3rd gen) isn't putting out sound other than static and high pitched noises through the tv hookup, the built in speakers, and headphones. Can anyone tell me what's wrong and how to fix it?

Everything on my iPod touch (3rd gen) works just fine except the audio out put.

Try #2 and #3 in link below. If neither work, you most likely have a hardware issue. Contact Apple or a third-party service center.

High-pitched hiss at the beginning of p

Hi,
I recently bought a Zen Micro. Everytime I press the play/pause button (or if a skip forward/backward) to start playing a song, I hear a whine hiss for about seven seconds on the top of the beginning of the song. I noticed also, when I am using other functions while playing, the same hiss appears. It's not as loud as the song volume but since I listen mainly to classical music I am hearing the hiss once in a while on silent parts of the music.
Is this normal? Anyone noticed this? Or is just my player?
Thanks

What you may be hearing is the amplified voltage used to write the song into RAM so as not to use the HD all the time during playback.
As to why you hear it ... I have used quite a lot of different earphones with the ZM, from the really cheap to the expensi've, and have not witnessed this.
I would say that if you do hear a higher voltage converted to sound output, then the conduct line for the sound inside the ZM is not isolated correctly somewhere.
Let me tell you why I think this: I recently installed a new lamp in my room, and did that quite amateurishly. After having finished, I noticed that my speakers would play up when I switched it on. I isolated all the bits of the cable that I had cut or merged to get it to the right length, and the crackling was gone. You have, in all probability, some lamp in the house that will make, e.g., a radio act up if you connect to a power outlet directly connected to the one you have the lamp in.
Cheers,
Jan.

No sound from my Macbook Air. When I go to system preferences and click on Sound Output there are no devices to select from and the Mute box is checked.

There is no sound from my Macbook Air even when I turn it on. When I go to System Preferences and click on Output there are no options. The Mute box is also checked, but I cannot uncheck it. Also when I try to play any video from the web, it stops playing after a second or so. I have turned off my computer and turned it on again which did not help.

Envy 14 1095la. High pitched whine sound and fan cycling.

Hi. I'm in contact with the customer service about 2 (and a 3rd maybe related) annoyances I have on my Envy 14 1095la (XC515LA#ABM) notebook. I want to share them here in case someone has some clues and guidance about them.
Fan cycles continously on and off every couple of seconds
... on light usage (using the low performance GPU and a text editor).
Reading the temps using Coretemp and HDinfo, I can hear the fan kicking in when CPU temp is above 35º and turning off when it reverts back to this value.
Enabling the "FAN ALWAYS ON" option on the BIOS (as suggested by the tech guy) has no effect over the problem (yes, the fan remains always on, but you can still hear it cycling RPM constantly).
Since this model has no option to regulate the FAN via software, the only solution seems to be a BIOS upgrade.
Sometimes, I can hear a high pitched sound coming from the computer.
Tech guy suggested me to experiment a bit with this to better understand what can be the problem. I've found so far:
Seems to be far more frequent if the battery is in place (without the battery I heard it only once, and quiet).
Seems to be more louder if the battery is in use.
The sound seems to originate from the Seagate Momentus HD, but It is so high pitched that makes difficult to point the exact origin.
Messing with the sound options (muting mics, audio etc) seems to have no effect.
Sometimes I feel a strong vibration on the palmrest
Perhaps related to the previous, sometimes I can feel a strong vibration on the right palmrest.
Resting the notebook over different surfaces (or lifting it in the air) seems to have no effect.
Reading a bit on this forum I can see that the Seagate Momentus HD is a strong candidate for the vibration+high pitched sound problem, but again, if anyone has a better idea or an aditional test I can made to be sure, is welcomed.
Thanks!

Well, notebook is out for repair.
I've in touch with a level 2 support guy that acknowledged that the "fan cycling" thing is odd and will pass a report to the engineer team (hope HP is not lazy because the Envy refresh and new BIOSes).
About the high pitched noice and vibrations, they will check the HD, but since SMART values are alright, I doubt they´ll change 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.

Mac Mini makes high-pitched sound when light images displayed on monitor

I have a Mac Mini 1.5Ghz G4 with 80GB/combo drive.
Occasionally, it will start to emit a high-pitched whine. The whine doesn't seem to be emitting from the built-in speaker. It comes intermittently. It stops as soon as I start shutting down the Macintosh, although if I wait it has stopped on it's own after a few minutes.
Here's the weird part.
I have some control over the volume of the pitch when it is occurring by changing the amount of "bright" objects on display on the screen. I have a dark desktop image in the background. When the high-pitched whine started, I was using Safari looking at a web page with a white background. When I hid Safari, the volume of the sound dropped to be almost unhearable. I switched to OmniOutliner where I had a single window open that was about half the size of the Safari window I hid. It too had a white background. The high-pitched whine returned at about half the volume it was at when the Safari web page was opened. I hid OmniOutliner, and it dropped down again. Resizing the windows led to a corresponding change in the volume of the whine.
I would take it in to a Mac Genuis, except the high-pitched whine starts when it wants to.
I've already googled the problem and all I can find is an instance of a video card in a PowerMac G5 emitting a high-pitched whine.
If anyone can illuminate some ideas on the fix or at least the cause of this issue, it would be much appreciated.
--Joshua
P.S. The monitor the Mac Mini is connected to is a Dell E772c.
Mac Mini PPC G4 Mac OS X (10.4.5)

If you search around you will find this is a common complaint, not of the mini, but of PowerBooks, iBooks and other PC notebook computers. The reason that people report this issue so frequently with notebook computers is because they are so, otherwise, quiet and that makes it easy to hear such sounds. I guess you can put the mini in the category of quiet computers.
What you hear is likely the result of a phenomenon known as magnetostriction. You are hearing magnetic cores, as found in chokes and transformers inside the mini, vibrate at their operating frequency, which can vary according to changing circuit loads, which is why it can be come-and-go and also change in pitch.
Below is a wikipedia link on magnetostriction if you care to learn more. It's nothing to worry about but it can be annoying. Makes you feel like you are sharing your room with a mosquito.

I tunes sound quality, sounds like a synthesizer, high pitched Mickey Mouse

NEED SERIOUS HELP. Recently moved, not sure if I Tunes ever sounded right since the move. Before moving I upgraded to the latest I Tunes version. I'm not sure if that ever sounded right, with the move going on I don't recall if I even listened to it at the old location after the upgrade.
In the new location at first I remember having no sound, but I thought that was just because my son is sharing the computer with me and he had his headphones plugged in. But when I unplugged the headphones there was still no sound. Later on I was able to get sound somehow, but it sounds absolutely horrendous..for example we're talkin James Brown vocals sounding like Mickey Mouse, like a high pitched synthesizer sound, as if many tracks are missing..I don't know how to describe it. All songs sound like this as do CDs that are played through I Tunes. I tried the fix going in QuickTime preferences and putting sound out to 48 /16 bit but it didn't touch it.
I have a huge music library and I'm absolutely freaking out thinking it is all corrupted. I have a back up but its a month or so old and I add about 10 songs per week. Ideas anyone????

By way of experiment, try heading into your QuickTime control panel again, go into the Audio tab, and try checking the "Safe mode (waveOut only)" box. OK out of the tab and restart iTunes.
Any improvement in the sound quality?

High pitch noise in CS4 and CS5.5

Hello.
Firstly I want to say that yes I know people have asked this question before but as far as I can tell none of them have been solved. Some have somewhat useful answers but none of them truely solve the problem. This thread in particular probably has the most information about the problem I'm having http://forums.adobe.com/message/4298535#4298535
I recently tried Premiere Pro CS5.5 and CS4 (trial version) to replace my Corel Video Studio X6 which tried to replace Windows Movie Maker. Video Studio and Movie Maker both crash whenever I imported large video files.
Anyway I'm getting a problem where the video files I import to Premiere Pro CS4 and CS5.5 have a high pitch noise in the video preview.
It's a high pitch noise almost like it's getting feedback from something. Also when someone is supposed to be talking there's a very low distortion, like the audio started playing in very slow motion but the high pitch noise is still present.
I'll put a link at the end with the video file that's giving me trouble.
The video and audio are in a single AVI file. The video format is H264 shot at 60fps and the audio should be Mpeg-1 L2, 48khz at 320kbps. I don't know if the video's audio is in 24bit or 16bit.
I've tried different settings for premiere. Trying 60fps and 30fps for the framerate for the project. Trying 44khz and 32khz and 96khz didn't fix it. Using the "Desktop" preset in CS4 and Custom for CS5.5.
My audio hardware is a Logitech G930. It's a wireless USB headset with microphone. My motherboard audio is Realtek HD Audio. Both are enabled but I only use the headset now and nothing is being sent to the Realtek audio chip (according to Windows' sound options). The headset plays audio at 16bit 48khz.
The video file plays fine in every media program I own that can play the h264 codec. With the exception of Movie Maker and Video Studio x6. Video Studio will preview the video and audio just fine but when I try and skip around the program hangs and crashes. Movie Maker just plain crashes when I try and import the video. Some of the programs that can play the video are VLC, Media Player 11, and Media Player Classic.
I'm not sure if Final Cut Pro has the same problem. I don't have a Mac so I can't test it.
Here's a sample video that works the way it should. I pulled a BIK file from a game and converted it to H264 in AVI. Not sure what it's audio format is.

Just click the download button at the top right.
Here's an afflicted file. Not the exact specific file I have been talking about, but it has the same codecs. This one is shorter in length and smaller in size. It still has the high pitch noise, but since there is no one talking in this you don't hear the weird low pitch distortions.

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

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.

High pitch whine noise from speakers and other issues

I just got a 2010 Mac Mini and transferred all of my data and apps and accessories from my old Mac Mini which was running 10.6.4 (2007 I think). One of the accessories is a Griffin Firewave. I had to get a new firewire cable to attach the Firewave since the new Mac Mini has a firewire 800 port. On the old Mac it worked great, I was able to run 5.1 speakers with no problem. With the new Mac things aren't so nice. I get a high pitch whine through the speakers. The whine will go up and down in volume with the volume control on my sound system (Klipsch Promedia 5.1 Ultra) as well as with the Mac volume control. I can increase the gain in the Firewave app which will increase the volume of what I want to hear without increasing the volume of the whine, however it will cause the audio I want to hear to distort. The other issue I have is that when I put the Mac to sleep it seems to cut all power to the firewire port, causing the Firewave to turn off and lose its settings. I believe this to be a bad design on the Firewave's part but the old Mac did not shut off the power to the firewire port when going to sleep so this was not an issue. So my questions are, does anyone else have problems with external sound cards having a high pitch whine noise and is there a way to prevent the firewire port from turning off when the Mac sleeps?
BTW, I have tried reinstalling the Firewave driver (several times) and I've unplugged and re-plugged the firewire cable at both ends. I have both the Mac and the sound system plugged into a line conditioner so I doubt it's dirty power. I do realize that the Firewave only claims support up to 10.5 but it was working without issue on the old Mac Mini on 10.6

I have the same problem. I have an early 2009 Mac mini and get the whiny noise from my powered speakers. The volume of the whine noise tends to change smoothly up or down, and often does a stuttering effect along with it. It stays there for up to a minute or so and then eventually goes away. It always seems to happen at random times.
I've heard this same sound effect coming from a podcast that I was listening to on my iPod Touch. It seems that the interviewer was recording from a Mac mini as well, though not sure. The sound in the recording was exactly like what I hear coming from my Mac mini. I often thought that this was a problem with my speaker system, but was surprised to find that others are experiencing the same kind of issues.
