Buzzing noise when connected

When I connect my touch to my computer (this happens with Mac and PC), there is a very short buzzing sound that last just a split second that comes from the device. I'm fairly certain it wasn't doing that when I first got it. I can't tell if it's from the internal speaker or something mechanical. Since the touch has a flash drive I assumed there would not be any moving parts.
Is this happening with anyone else's?
Should I be worried about it?
Thanks.

Are you sure its the Touch speaker? With my iPhone the wifi makes various sounds that bleed onto my computer speakers. And sometimes I thinks its the iPhone.

Slight Buzz/Hum When Connected To Mains Adaptor

My MacBook is making a slight buzz/hum at the top left of the keyboard (by the esc key) when connected to the mains adaptor. It seems to be in the area of where there the magsafe connector is. Assume its the power 'board' or whatever its called making the noise.
The buzz seems to come and go, especially when the hard disk is accessed.
Just wondered if anyone ekse has experienced this or if I should be raising a support call as the MacBook is only a month old.
Regards

I believe it's a CPU whine you're refering to. Try
opeining Photo Booth and see if the noise stops.
The noise is still there.
I've reset the SMC as well.
The noise is only slightly noticeable and ONLY there with the power adptor connected.

Constant electical buzzing noise when off. Normal?

I have a W520 that makes a soft electrical buzzing hum, kind of like a florescent light bulb. It does this only when I turn off the machine, and the hum changes pitch every 2 seconds, but it is constant. The only way to get it to stop humming is if I turn on the machine, or remove and reinstall the battery.
The computer is new. I bought it direct from Lenovo and just received it on 7/14/11. It has been making this noice since I got it, but because this is my very first laptop, I don't know if the noise is normal.
I called Lenovo tech support and upgraded my drivers as advised, but this hasn't solved the problem, so I was told to call Post Sales Department on Monday to see if I can get a replacement W520.
Has anyone ever experienced this with their W520? Is this electrical humming noise normal? I have confirmed that it is not a fan noise, or a hard drive noise. There is no movement or vibration in the machine, it just likes to hum all the time when it's supposed to be off. Our IT guy at work thinks it may have a bad connection somewhere that is causing capacitor noise.
My W520 is a model 4270. Core i7-2720QM, Quadro 1000M, 8 GB SDRAM/500 GB HDD, running Windows 7.
Thanks.
Solved!

Thanks. I got a return authorization and shipped the computer back to Lenovo today. The post sales dept is going to give me a refund when they get the computer, and once I get the refund, I'll have to order a new W520.
Hopefully, the new W520 will not have the buzzing noise problem.
I'm really glad that the post sales dept allowed me to return the computer instead of having me send it to a depot for repairs. I wish they could have just exchanged it for a new one, but because it's over 21 days from the order date, they have to give me a refund instead.

Buzz/hum when connected to krk studio monitors

ok so i have an imac (3.06 ghz intel core duo). i had a klipshe 2.1 speaker system connected with no problems. then i bought a pair of krk rokit 6's studio monitors and just have a whole lot of humming now. so far ive connected headphones to my imac and no hum.... connected my ipod to the krk's and no hum..... connected my krk's to my macbook pro (while it was plugged into the same outlet as my imac) and no hum..... bought a m-audio fast track and connected the krk's through that to my imac and still it hums.... what gives? please help. thanks
shawn

Shawn, I am getting a 1 KHz whine through Behringer Truth monitors using M-Audio USB Fast Track Ultra audio/midi interface with an iMac i5 27-inch with LED monitor. The whine occurs continuously from the moment I open Logic Studio or iTunes, when the output is routed through the Fast Track Ultra. The whine does not occur when I use the imac output to imac's speakers. I also get an electronic scraping noise when I use the blue tooth connected magic mouse. I have installed ferrites on the monitor speaker wires with no reduction in the whining noise or electronic scraping noise. I have also ordered the USB with ferrite collar to see if the connection between audio/midi interface and the imac is the source of the noise. I am considering a Hum-X, as well, but I am getting into serious money taking stabs at a problem for which there ought to be plenty of competent technical support. The fact that this whine is at 1 KHz and not lower suggests that I am not suffering a typical ground loop. I am a former Pro Tools user who never had a hum or whine from my Digi and G4, which I am seriously considering recomissioning so I can make music again. I am spending way too much time and money making educated guesses and trying to diagnose a problem that all but kills the utility and purpose of this new system. I too am calling on all great engineers to step up with a diagnosis and solution.

Odd buzzing noise when on BOTH AC & Battery

My PowerBook has a strange "buzz" that sounds like white noise (or crickets, like my old G5 used to) when it is plugged into the adapter AND with the battery in. When the notebook is on just battery or just AC power, there is no noise.
What is my problem?

Hi, I had the same problem, at least symptoms. Changing energy usage to low worked fine, but I use graphic intensive software so I need the high performance output. I posted the below information on a separate article as well, but I wanted to share it in case anyone has the same problem and wants a possible better fix.
--- previously posted---
I recently had a loud screeching buzzing noise, not the very faint hard drive or fan sound, but a loud annoying sound. After searching hours online, I found an answer for the problem. (in my case at least)
If you have any speakers plugged into the same energy source (i.e. powerstrip), that may be the problem. I unplugged a set of Sony speakers I had running along the same chain of AC powerstrip outlets, and the noise was gone. The article I found was here: (look for the post by "ST" about midway down this page:

Buzzing noise when iPhone 4s vibrates

My new 4s buzzes loudly when the unit vibrates. It is not the sim slot or door as the noise exists with the sim and door out of the phone. The buzzing is almost as loud as an audible tone and quite annoying and distracting. Anyone else with this issue?

I have the same problem. Even holding my finger on the bottom right corner eliminates the buzzing noise. I think that the screen could be slightly loose.
I don't mind this when it's in my pocket, but the alarm gives me a bit of a shock in the mornings now.
And I don't really want to exchange the phone, because it's perfect otherwise. I definitely don't want to end up with a faulty screen some of the people here are reporting.

Macbook pro making buzzing noises when using google chrome

I have had a Macbook Pro for at least 3 years. I have always used Google Chrome(in fact as I am writing this it began making this noise while using Safari) to use Google Drive to work on my homework to do other things as well since I find it easiest to use for school. Recently my computer has started making a very loud buzzing noise near the fan areas when I use Google Chrome and it worries me. It had that problem before, but when I took it in before I thought the problem had been fixed. Now 2 years later it is making that noise again and it only goes away when I put my computer to sleep. I am unsure as to what to do about it and it worries me because it is getting to the point where I can't even use my computer to work on it.
Please help or give some advice on what to do.

Open the bottom and use a can of compressed air and clean out your fan for dust and possible plastics stuck near fan blade. It will help and if needed replace fan https://www.youtube.com/watch?v=Mu6tKVqdgGI

Buzzing noise when fast forwarding live tv

After pausing live tv, then fast forwarding, it's started to make a buzzing noise whilst forwarding then stops when playing. It doesn't do it when rewinding.
Anyone else experienced this?

Yes I've been getting this since the new update. Buzzing whenever FF or RW on demand, recordings etc, even sometimes when changing between adds on 4oD. It sounds like something to do with the hard disk. I've just put it down to an ageing box reaching the end of its life, sad really but I suppose 2yrs is what we should expect from these types of products.
How old is your box?

Loud buzzing noise when I play music and watch videos. Happens through speakers and headphones

Hey guys would really appreciate your help.
I bought a HP laptop in January which started to make buzzing sounds when playing audio from iTunes and YouTube as well. I thought the laptop was faulty so I returned it.
I then got an exchange and instead got a hp-15-d051sa and it does the same thing! I have looked everywhere on these forums to resolve this issue and one source said to uninstall the HP assistant but my laptop is still doing it. It happens on both my speakers and headphones.
Any help will be much appreciated because this has happened on two brand new HP laptops so I'm sure this is happening to other people as well.
Regards,
N

Same with me nothing has changed. However what reduces it for me is if you change your battery settings to high performance. But it still does it, you will just find it will do it less.

HORRIBLE BUZZING/HUMMING WHEN CONNECTING SYNTHESIZER TO GARAGEBAND?

Hi! I want to connect my synthesizer to garage band so that I can use it as a live instrument when recording. I have a MobilePre USB from M-Audio. I just sent for an Imic, and I just bought a guitar cable adapter today from Griffin. Ok, when I use the M-Audio I get a horrible hum. I've tried different wall outlets, different volume settings, nothing works! When I plug directly into the computer using the guitar cable adapter I get a buzzing sound. It's the same kind of sound you might get through a guitar amplifier when you are playing live. It's infuriating!! If I would have known that this was going to happen I would have never invested the money. Is this what happens with all instruments that have their own power? Will the Imic get rid of the buzzing? DOES ANYONE KNOW WHAT I CAN DO PLEASE? HELP! Thanks, Jim.
Power PC G5 dual processor Mac OS X (10.4.3)

try plugging it into an amp, and see if you get the same results. With the Mobile Pre, you didn't need to get an iMic or that cable stuff. The Mobile Pre is a better usb interface than the Griffin stuff. If you still get the noise through an amp, then try a different cable. You shouldn't be getting that with any instrument. There's a problem somewhere in the chain. You'll have to test each link in the chain to try and locate it. Do you have other instruments you can try?

My Macbook Pro with Remakes funny noise when connected to power supply cable and no other response. The best description of the sound I can give is the buz the computer makes on startup. Sound goes on and off while connected

I am new to the Macbook community. I own this Macbook since 10/2012.
My Macbook Pro 15 with Retina Display suddenly totally stopped responding. No display, no activity on keyboard. When I connect power supply cable, the Mac makes a noise as if it is starting up, but this lasts a second and this sound comes and goes the whole time the power cable is connected.
Any advice?
Thanks!

Nasty Buzzing Noise when using external charger

I've got a travel charger made by iWantit (iPod & Nano compatible) that I've always used to charge my nano when out and about. When I connected my Touch to it the screen showed a flashing charging icon in the top right and the Touch started buzzing erratically as if it wasn't happy. I should add that I'd had a low battery warning message just before doing this (less than 20% I think it said). My question is can I safely use this travel charger to charge the touch or does it have different specs to the other ipods for charging?

I suppose what I really need to know is whether charges have damaged any ipods. Maybe I should film it for YouTube so everyone can assess the threat level for themselves.

Buzzing sound when connecting my new airport express to bose system

I recently purchased the new Airport express with the purpose of streaming my music from itunes to my bose system. As soon as I connect my stereo to the Airport express a loud buzzin sound comes out even if the stereo volume is low.
I've tried the same cable plugged straight from the stereo to my ipad or laptop and this buzzing sound is not there at all. This only happens when I connect the stereo to the new Airport express.
Please help, before I have no option but to return it.
The device firmware is up to date.

Temporarily, plug a pair of headphones into the audio jack on the AirPort Express and test to see if you still hear the buzzing.
If no, then the Express is operating correctly. The issue is somewhere else....either an intermittent connection in your audio cable, or the jack on the Bose system is defective.
If you still hear the buzzing when you test the AirPort Express with a pair of headphones, the Express is defective and will need to be returned.

HT1338 buzzing noise when i adjust my brightness?

Is there an easy solution to fix the noise from my brightness adjustment?

Hello TommyJon,
Welcome to the HP Forums! I hope you enjoy your stay!
I understand that a buzzing sound is produced when the "W" key is pressed. This is normally a hardware failure, and I would contact HP support for assistance.
