My left speaker makes a strange noise (buzzing) when my mac starts up?

After logging into my MacBook Pro my left speaker makes a strange noise that lasts about 5-7 seconds then stops. No other problems with sound quality or further noises after start-up.
Problems arises both upon starting the mac from "off" mode and "sleep" mode.
Recent problem that started 2 weeks ago. Mac is aged 5 months old.
Any help or advice would be appreciated!
Thanks folks

    my eraphone of my iphone 4s white unlocked make strange noises during the call and still doing the noise like an interference or saturing the spekaer

    This is a common problem with iPhone 4s (and IOS 5)  There isn't ' anything you can do about it, so you're best bet is to go down to the store and get an exchange. If you have an older iPhone (3gs/4) roll back your update from IOS 5 to IOS 4.

  • Strange noise buzzing behind my Mac

    Lately my Mac has been making a weird buzzing noise from behind the screen. It might be the fan or something, but I hate to say it, but I hit the back of the computer and the noise stops. It only happens after my computer sleeps overnight or for a long period of time and then when it starts up, it makes that noise again. I have been reading other posts about this noise, but not sure if anyone had the same solution as me that hitting a certain spot stops the noise. It has nothing to do with how many programs are open or if a certain one is open.
    Has anyone had this problem and has anyone fixed theirs? I do not have the apple care warranty anymore, but not sure if there was an easier fix or if I should just take it in or if I just need to suck it up and do what I have been doing. Also, I am not sure if doing the hitting is going to damage my computer in the long run. Any help would be appreciated. Thanks.

    I wouldn't keep hitting it; that could be quite bad for the drive if it's spinning. Could be a few things, but sounds like it might be a bad inverter, but you should at least bring it in for diagnosis for which there is usually no charge. When this is happening do you notice any difference in the screen? The inverter supplies AC current to power the fluorescent backlight of the screen. The buzzing noise maybe not very different from a buzzing fluorescent bulb.

  • Satellite P200 makes some strange noises after closing the music

    I've got a Satellite P200 and the flash cards don't react and when Ive played some music.
    The computer makes some strange noises after closing the music?
    Help me please!
    grtz Wendy

    Hello Wendy
    Please don't understand me wrong but it is not easy to understand issue described in your posting.
    I have the same notebook model and everything works well. I hear music daily on Windows media player (mp3s) or listening online radio using Winamp player.
    At the same time I can use flash cards.
    What to say about strange noises? Who knows what do you mean exactly and how should we understand this?
    Please be so nice and explain us exactly what do you do and what kind of noises you can hear.

  • IMac 27" strange electric buzz when it is in stop

    I have a problem with my iMac 27", whent it is in stop makes a strange electric buzz.
    I have reset NVRAM and SMC but it's still there.
    PS sorry for my English, I'm italian

    At least get the free diagnostic test which the AS & AASP's offer.  This is the only way you will get confirmation of what exactly is wrong w/your iMac.  You can always come back here to tell us what the problem really is & possibly get some DIY (do it yourself) instructions and/or links.

  • Why does my ipad 2 make A strange noise

    why does my ipad 2 make a strange sound

    Without further information, it will be hard to answer that question. What kind of noise? Under what conditions?

  • Left speaker on macbook pro retina buzzing!?

    A slight buzzing sound can be heard from the left speaker on low frequency sounds, its not that loud but is noticable and quite annoying.
    Macbook is still under warranty, is it worth taking it into the store or is this not a problem they would consider for repair or for replacement?

    Take it in for replacement.  In time, the annoyance will become intolerable.
    Ciao.

  • My ipod touch makes a strange noise when makes the synchronization with itunes

    At first my ipod touch began doing strange noise in differents situations. Yesterday I try to solved it doing this: I connected it to itunes a made a restore. I thought it was solved, but today the noise came back.  I could identify when it happens. If the ipod is off and I plug the usb cable, itunes starts and the ipod turn on, then the first thing it do is connected to the wifi network, then syncronizations began and the strange noise is heard.
    Some idea?
    Do you think it would be neccesary to visit an apple store to solve it. My ipod is even covered by warranty.
    Thank you very much.

    Hey DerikK,

    P.s. it might start producing sounds after 5 min recharging..

  • Left speaker on MacBook Pro is static when using FaceTime?

    When I either receive or place a FaceTime call on my MacBook Pro, the left speaker cuts out audio and produces high static.  The right speaker is fine.  The receiving end can also hear the static feedback, but their two speakers work fine.  I have all my iOS devices setup to receive and place FaceTime calls (iPhone 5s, iPad, and MacBook Pro 15 inch late 2011).  If I place or receive the FaceTime calls on my iPhone or iPad, there is no problem. 
    I've tested the speakers, youtube, iTunes audio, streaming websites, netflix, etc... and all works fine on the MacBook Pro.  Just FaceTime.  I also went into system preferences and the speaker setup is correct (audio in and out - internal speakers).
    I've also restarted, reinstalled Yosemite...still FaceTime left speaker problem.
    I appreciate any troubleshooting advice and/or if others have experienced this problem.
    Thanks!

    Take it in for replacement.  In time, the annoyance will become intolerable.
    Ciao.

  • Hi, since doing the latest update my phone makes a strange noise everytime i send or recieve a text even when there is no text tone set?

    hi, since updating my iphone 3gs with latest software it makes a noise when sending/recieving texts even though there is no text tone selected

    Hi Thisslowgt,
    If you are having issues with your iPhone making unexpected sound signals, you may want to try some things to troubleshoot.
    First, quit all running applications and test again -
    iOS: Force an app to close
    Next, I would try restarting the iPhone -
    Turn your iOS device off and on (restart) and reset
    If the issue is still present, you may want to restore the iPhone as a new device -

    Thanks for using Apple Support Communities.

  • Why does my speaker make a humming noise?

    Its kind of a high pitched whine. It's there whether I am listening to anything or not, anytime I have the volume on. The higher the volume, the louder the hum. It's less than two months old.

    did you ever find out what was causing the problem? The same issue just began with my phone. the audio recording is fine for voice memos, phone calls, etc. but the video is just a buzzing sound

  • My ear pods make a strange noise when I'm not listening to music.

    My earpods make a ZZZZ sound whenever I'm not listening to music.When I touch my iPhone screen the sound increases.I've had this problem since I had my iPhone 5.Is this normal?

    AC/DC adapters come in different designs, and the higher current output of the iPad charger uses a different design than the iPhone (or iPad mini) charger.  Most adapters these days are "switch-mode" design for better efficiency, but I suspect that the iPad charger may be a linear design, such that one tap of the transformer is tied to the ground lead of the dock cable, and thus the iPad shell.
    You'd be shocked (pun intended) to know that the voltage on the iPad shell may be about half your line voltage ... it is about 40-50 VAC here in the US, or if you flip it around (since the US charger is not polarized) it may be only about 20-25 VAC.  But as I said, the supply is current-limited, and is well within international safety limits.

  • Strange noise appears when printing

    I am running into some issues when trying to print a post card I designed for a client. I created the card in photoshop cs5 with a resolution of 300. After creating it as a psd I exported it as a pdf and then printed it through acroabt x on a xerox 700 digital press using creo rip software. The print looks ok-ish until I look at it under loop. Through the loop I can see alot of digital noise around the text. I printed it again directly from photoshop and removed a background image that was behind the text and that cleaned up some of the noise. Although the text still a little noise. Can any one think of why that might be?

    thanks guys,
    Peter, I'll try your suggestions. As you see, everything looks fine on screen with the PDF. These little 'boxes' appear only when I print.
    "Also, make sure your transparency blend space matches your backgrounds." How do I do that?
    Ken, as you may remember from my previous posts, I'm new at this so forgive my lack of knowledge. Does 'banding in the gradient' mean you are seeing horizontal lines down the image? I don't get these on my prints but the text box holding the "Cello/Celli! A Celebration of the Cello" prints with the background of the box visible against the gradient behind it. I also get a similar effects below the blue box holding the 'time & place' info. both of these elements have a drop shadow applied.
    BTW, my PDF does show faint lines oulining the 'CC' logo text boxes. These don't seem to print but I want to be sure. The logo was created by grouping two text boxes and applying a transarency to them. Hey, now that I look at my print problem it seems as if these 'logo' text boxes might also be having 'compatibility' issues with the backgroung gradient?
    I don't know nutin. Thanks for the help!

  • Strange noise from my new mac pro

    Bit of a silly question: my Macbook Pro keeps making these short 'whooshing' sounds, but I just can't figure where they're coming from, or why they're happening. I notice these when I have just my browser and/or iTunes running. It's from some software (i.e., not a fan noise). Any ideas?

    Hello, thanks for the responses!
    x4...: Haven't tried using another account; my computer has only one registered currently (it's spanking new)
    I did try logging into safe mode - while I received no indication that it was on safe mode, all sound functions appeared to be terminated when I logged on after long-pressing Shift. Panicked in a small way there, ha ha.
    Bart..: Quitting email clients (mail, gmail, outlook on web) didn't help
    And nope - no one else logged into computer.
    All this said, the sound has stopped mysteriously right now. There's a good chance it'll start again though (it's done this before, with no connection to newly opened programmes or anything)
    Thanks, all!
