High pitch screech when LAN is transfering data over network

I found this strange. But whenever data (large amounts) is sent through my puter over the network, the LAN chip or whatever makes a high pitch sound. What is with this?

Firewall enabled and for example opening a torrent with more than 100 peers made the northbridge screech and crashed the network after five minutes. Disabling the firewall helped a bit, removed the screeching atleast, but it's still lagging behind my old AT7-MAX2(VIA KT400) onboard LAN in 'performance'.

X-Fi Elite Pro: high pitched screech and blue scr

So far I have:-cleansweeped the drivers-cleared all temp folders-uninstalled all creative software-clean booted xp for remove, clean booted to install-tried installing the drivers on the cd, the web, and through windows update-adjusted my pc latency-installed new nforce drivers-installed chipset drivers, & display drivers- I only have one PCI slot, so I can't try another slot-disabled my onboard audio-checked irq's, windows doesn't report any conflictsWithout the drivers my system operates normally with no sound. As soon as I install any form of the drivers, the next time my computer starts, I hear a 'click' in the X-Fi, and the computer hangs indefinately with the HDD light on.Any help is greatly appreciated - completely unusable right now

Well after spending over a week and probably 20 hours trying to troubleshoot this issue I am about to give up. Thanks to those who have tried to help.
Current status is I have a fresh install of WIndows, no software installed whatsoeve other than the X-Fi software. I have been able to get my X-Fi to power on. It may even work for a little while.
However, without fail, eventually my system will lock up, sometimes producing a high pitched screech, other times BSOD and restarting (and then BSOD -3 more times while trying to boot).
It's just not worth it to spend this much time trying to get it to work.
If anyone has any additional helpfup information I would be most appreciati've. Thank you.
Again relevant system info
Nforce2, with AMD chipset - Geforce4 4200, XP service pack 2. I have disabled my onboard audio.
THanks again

WRVS4400N makes high pitched screech

As subject my WRVS4400N emits a high pitched screeching noise constantly (unless powered off). Does anyone else experience this?
I'm assuming it is down to hardware - can anyone offer a quick fix or is it an RMA?

If it is emitting a high pitched screeching noise constantly I believe it is a hardware problem. I think it will be better to call there tech support so that it will be replace it if it still under warranty.

Recently bought new macbook pro , transferred data over and thought microsoft office would work on new laptop. Icons are there , although don't have my key codes!! should i just buy new software package ?

recently bought new macbook pro , transferred data over and thought microsoft office would work on new laptop. Icons are there , although requires key codes and I don't have my key codes anymore as dog chewed the packaging!! should i just buy new software package ? I am told that this is a microsoft issue not a mac issue !! But all my other data on the old macbook pro transferred over even the icons for office for mac on the bottom app bar. only now I can't open any of my word or excel files without key code! I thought that there may have been something that could be done before having to bite the bullet and fork out for new software package.??

If this is Office for Mac 2011 then it will work on your new computer. Reinstall it. If you don't have the key code call Microsoft's activation line to get a new key code. Explain that you lost the original key code and want to install Office on your new computer.

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
Cheers,
Denny

OSS makes very high-pitched sound when turned on

I recently replaced ALSA with OSSv4 on my Arch install. The sound quality is much clearer, but when I start OSS it makes an extremely loud high-pitched sound.
I have determined that the sound is coming from input-mix, and I have temporarily solved the problem by checking "input-mix-mute" in ossxmix, but sometimes the mixer settings do not get applied when I boot, and I am forced to shut down my laptop to stop the sound. Do you have any idea why input-mix would be outputting this noise? I would really like to get rid of this problem.

Quick update - I brought my iMac to an Apple Store, and they identified the logic board as a probable culprit, suggesting a complete swap of the logic board for a cost of >1000 chf (700 USD) - so for now, I haven't fixed it but bought a electrical socket that I can turn off, which (sort of) fixes the problem.
Unfortunately 2 weeks later the screen decided to give up working, flickering and then pitch-black. Numerous phone calls and store visits later the ony option I'm given is again to replace the logic board. As the unit is over 2 years old and I did not purchase AppleCare, that leaves me between an expensive fit or buying a new one...

ITunes high pitch noise when in full screen on 27" iMac11,1

Hello,
When running iTunes 10.5.1 in full screen mode on Lion 10.7.2, I get a faint, high pitch noise coming from my speakers. If I run iTunes in a refular window, the noise does not manifest itself. I can switch back and forth between one full screen app and iTunes, and the noise goes on and off and only manifests itself in iTunes.
Has anyone else experienced this?

I think I've found a workaround. The problem doesn't only happen in iTunes, but also in the Finder's list view when in full screen.
The workaround is to use Shades, a small utility that creates a uniform black color mask over my screen. All I had to do was set the brightness of my screen to 100%, run shades and lower the "brightness" using that utility to something comfortable for my eyes.
I think the issue comes from the high frequency flicker that the LED back light uses when the screen is being dimmed. For some reason, the speakers pick up on it when in list view... Why only list view? Beats me.
Anyway, the Shades prefpane can be downloaded from the following URL:

I hope this helps.
All the best!

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:

High pitch squeal when turning up volume and an echo sound

I have never gotten good audio from my computer......any time I want to watch or hear something I have to turn it up to about 35 before I hear anything and then a deafening high pitch squeal happens that makes it impossible to listen to anything.....if I plug in my headphones there is so much feed back with a horrible echo sound that I cant stand to listen for long.....I want to know if there is anything I can do to get decent sound from this laptop. tia

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.

X-fi Extreme Music - Mouse making high pitched noise when moved

? Whenever I move my mouse my headphones make a very high pitched noise. I moved my mouse to all usb ports and it still happens, cant change my IRQ in bios and vista has them all locked out from being changed. I also have my X-fi as far away as possible from my video card. I have no idea whats doing this but i need some help.
Specs are as follows
P5Q-PRO
Q6600 @ 3.48GHZ
4GB Mushkin @ 078
X-fi Extreme Music ***Lastest [email protected]

I've never had pictures of the mod, as it is it wouldn't show up vey well in a photograph, not to mention that every front panel board is different from one manufacturer to another. Mine came with my Gigabyte Aurora case, but Gigabyte probably didn't manufacture the circuit board itself.
I had the noise problem when I first tried out my new Bose headphones with it and knew I needed to fix it. The main issue is the metal mounting studs that attach the board to the case front cause a ground loop with the grounds coming in from the sound card, as well as the motherboard USB headers. Having all these grounds just connected together like that is the root of the problem. By far the worst issue is the studs being connected to the foils on the board. Scraping the foil off the board where it makes contact with the studs will probably fix most of the noise. Next, cutting a gap in the foils between the incoming grounds from the sound card and USB headers will clean up more noise. If properly done, and all plugs removed from their headers, there will be an OPEN connection between any one ground wire and another, as well as there will be an OPEN between the chassis (case) and any of the ground wires. The ground wires coming from the headers should show a good connection to their appropriate socket ground on the front panel, but again, an OPEN between each other.

High pitch whine when recording audio & voiceover in iMovie

I have read other posts on similar issues but found no resolution
Issue:
When recording video in iMovie there is sometimes a high-pitched whine which renders the video useless.
The problem was intermittent ... annoying but I wokred around it by re-recording the video enough times to finally get a "clean" copy.
Now I am recording voice-overs for some clips and the awful whine is present in ALL the voice-overs.
I have tried the "trick" of using brighter light. No joy.
I have tried adjusting the microphone settings. No joy.
THis is an older macbook ... so I can't trade-in for a new one on warrantee.
Is Mac's internal microphone defective? I have read enough other people have similar issues to think this.
I am doing educational videos. My initial joy at being able to record a video on my macbook is changing to despair as I have wasted hours of time on tech problems like this.
Anyone have a real fix?
Is the built-in camera and mic just shoddy junk which doesn't work well?
Thank you

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 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.

High pitch ringing when recording voiceover

I just started getting a ringing when recording voiceovers. Any idea why?

I am using a Blue Snowball mic. I am also using Sony MDR-7502 headphones. There is a constant high pitch ringing.
In the past I've done voiceovers in FCP with this mic and no headphones without any problems. Since I tried to use the headphones (I bought them today) I'm getting the what I guess is feedback. Even when I unplug the headphones and plug the speakers in, as in previous set up, I am continuing to get feedback. (if this is feedback). This didnt happen before.
Any ideas? I've tried monitor on and off. Turned off my external hard drive. Checked automatic level control. I cant figure this out. I am new to setting up an evironment for recording other than my previous set up so maybe its something basic. You mentioned doorbells and phones. Does that mean nothing metal near the computer such nail clippers or hard drive? Do I need a shockmount? Is that the problem?
