External speakers buzz when charger is connected

My Cambridge Sound works speakers have a continual buzz, but only when my computer is plugged into its power source.
Any solutions?

I have the same problem with speaker buzz in my mini. I changed from Cambridge Soundworks speakers to KRK Rokit 5, but the buzz persists. I took my mini to an Apple store, but was told there was no problem. I doubt that one could hear the buzz in the noisy store.

  • External speakers buzz when FW HD connected

    I bought couple of external firewire Fantom drives to store my mp3 files but when connected to the PB they cause the speakers (external, powered) to emit a buzz that sounds like they pick up the HD spinning noise. It doesn't happen with iMac or any other hard drives I have (including older Fantom). Length of the cable, position in chain (if chained) or the placement don't seem to matter. Any insights?

  • Speakers buzzing when laptops on

    speakers buzzing when laptops on? Hello,
    I have logitech x-530 speakers and they buzz when the laptop is turned on. These speakers are connected to my desktop PC and work fine when the laptop is turned off, as soon as the laptop is turned on they buzz all withing the /4 volume range but it fades out the louder you turn the speakers up.
    Has any one any idea of this? as it has done it with various sound cards, motherboards, cpu, ram, and routers so I am guessing they are not the course.
    I just replaced the motherboard, soundcard, cpu, router less then a month ago but was doin this befor then as well. But seems to be louder now then it used to be
    my specs now are:
    logitech x-530speakers
    creative soundblaster x-fi xtremegamer fatalty pro sound card
    gigabyte MA790GP-UD4H motherboard?
    amd phenom II 940 cpu
    nvidia 9800 gtx+ graphics card
    2 sticks ddr 800Mhz OCZ fatalty ram
    netgear DG834N router (modem)
    not sure if any the computer parts are the problem, the laptop is also connected threw wireless its not on the wireless N network but can be changed if that may help.

    Hi there,
    I've a bit of a bizarre issue, and I'm wondering if anyone has any suggestions...
    I recently acquired a set of Mackie MR5 reference monitors, and am running them through a Tapco LINK.usb audio interface. They work great, with the exception that +anytime there's something move on the screen, they make a horrible buzzing sound+. The greater the movement, the more they buzz (or hum or whatever you want to say). Everything from moving the cursor back and forth to moving an entire window back and forth. Even if I turn the speakers down (via the audio interface), the volume of the buzzing remains the same. I booted the iMac in to Windows, and the sound is the same, so it is not an OS issue. I thought it may have been the video card making the noise (from within the computer), but the sound is definitely coming from the speakers.
    Here's the punchline: if I run an extension cord from across the room and plug the speakers into it, the buzzing becomes substantially quieter. It's still there, but it becomes very faint. This leads me to believe that I'm dealing with a power issue in the computer, but am now uncertain what to do. I unfortunately cannot run this 50' orange extension cord across my studio for any amount of time.
    Any suggestions would be greatly appreciated.
    Thanks!

    Neal,
    Have you tried another mouse??? Maybe that is causing the issue...
    Also, are you plugged into a 3 prong grounded outlet?

  • TS1550 What about when using the "Time Capsule" HD as the external disk, especially when it is connected by ethernet cable? I'm having trouble getting it to work at all. Don't need it to work as anything else, other than a ethernet connected Time Machine

    What about when using the "Time Capsule" HD as the external disk, especially when it is connected by ethernet cable? I'm having trouble getting it to work at all. Don't need it to work as anything else, other than a ethernet connected Time Machine backup. Already have a wireless network that works fine so no need to mess with it. We get the internet via cable company and their modem is upstairs and the Time Capsule is downstairs in the basement. The latest error message was about it could not backup as it was already in use (should have written it down before clicking OK and moving on.

    See if this helps...

  • IPad makes beeping sounds when charging while connected to mac

    iPad makes beeping sounds when charging while connected to mac

    First off, I suggest using the charger that came with the iPad and plug that into a good wall outlet. USB ports often do not supply enough power for efficient charging on an iPad.

  • Inbuilt speakers buzz when volume is maxed?

    When i turn the volume up on my 13" MBP, the speakers will buzz, slightly like distortion. Only when noise is being played through them.  There is no buzz when headphones are attached... how do I fix this, and/or will it be covered under the one year warranty it came with.  Also, if I buy apple care, will it cover anything if it breaks? like software and external problems? (like the speakers, or cracked screen etc.)

    Hi m,
    These speakers are small and not intended for playing loudly. No one here can give you an answer as to whether Apple will consider it a warranty issue, so the best thing to do is contact Apple. Buying an Apple Protection Plan does not cover physical damage (a cracked screen due to impact, dropping it, spilling on it, denting it, etc.).

  • Charging error message when charger not connected

    My phone woke me up an hour early today with an error message that I was using the wrong charger for my phone.  I am using the original charger.  The message keeps repeating even though no charger is connected.

        I'm sorry you're receiving this message mspammij. Are there any issues with the charger or charging port on the phone? Is either damaged? Did you start to receive this message when you downloaded a specific application?

  • Buzz when charging

    I really want this problem SOLVED
    Problem> as mentioned in title . Buzzing sound ONLY when charging . When charger is removed, no problems in audio at all. 
    Bought this ultrabook in Singapore (envy 4 1209tx). I am currently residing in Germany and spoken with the Hp Support in Germany, they will be sending me a new charger with 2 pin. I personally think its not the problem with the charger unit at all because i previously have a HP pavillion and  it was functioning properly even with the 3 pin charger.
    Lots of thread mentions this problem but almost close to none have been solved. HP what are you doing about this??

    Hello asper2,
    What is your product number and operating system?
    Thanks!

  • External speakers "pop" when mac mini is asleep

    I've got some Creative 5.1 speakers plugged into my mini, only using the left and right speakers. When the computer is asleep, the speakers make a popping noise that lasts through the computer waking up and until I change the volume on the computer. As soon as I change the volume, the popping stops until the next time the computer goes to sleep -- then it starts back up again.
    Any clues on how to fix this? Thanks!

    The problem is in the design of the speakers.
    The amplifier circuit works any time the speakers are on. When there is no music, it amplifies the noise that is present. Some circuits have leaks and collect electricity until it builds up. Once it reaches a high enough level, the capacitor discharges and you hear a pop.
    The mini should send no signal when sleeping - you can check this by disconnecting the speaker - but leave it sitting in the back of the mini. All of the cords at the back of the computer emit electricity - expecially the power cord. Having the speaker cable next to the other cables - it acts like an antenna and picks up noise. You might have luck shielding your speaker cable if this really annoys you. Otherwise, you need to get a better amplifier in your speakers to filter this noise or reduce the leakage current.

    Hi Sandy,
    If you set EXTPROCS_DLLS=ANY in the listener and then restart the listener, does it fix the problem?

  • Chirping when charger is connected what is it?

    iiPad 2 has chirping sound when plugged into charger, and battery charge icon shows AC wall plug symbol. The chirping eventually stops and the iPad charges.  Is the wall charger having a problem?

    It should only chirp once. If it's doing it a lot then your connection might not be good, you can see if it's not fully seated in your device. Or there could be an issue with your charger.

  • Mdr-1rnc Buzzing when charging

    I bought a pair of headphones [Mdr-1rnc] back in May of this year 2014 but have been having problems with them 
    If USB and audio jack are plugged into same system e.g. a laptop then there is a loud audible buzz. 
    When I spoke to support they said that the problem was with the device and that they would not be able to repair it.
    Has anybody else experienced this problem?

    Hi godzillalad,
    Welcome to the Sony Community!
    Sorry for the late reply. Please perform the following troubleshooting guide:
    1. Kindly check the connections in both ends.
    2. Try to plug into different USB socket
    3. Try to use different USB cable.
    If the issue still persist, I kindly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/.

  • Why doesn't my iPad2 chirp when charger is connected?

    My iPad2 stopped making the chirp sound when plugged in to charge.

    Right under the volume rocker switch is a little switch that can be either rotation lock or all mute. Perhaps if you have it muted then it doesn't even give the charging chirp

  • Strange issue with external monitor, only working when external speakers plugged in (using Thunderbolt to VGA adaptor)

    Hey – I am having a very strange issue with my external monitor; where it only works if my external speakers are plugged in and connected.
    I am using a late 2011 Macbook pro, running Mavericks 10.9.4, along with an MBox 2 (USB Audio Interface), and two powered speakers (KRK Rokit 5). This setup has had no issues. I have just acquired an external monitor (Benq T2200HD), which I am using with a thunderbolt to VGA adaptor (a cheap Chinese knockoff adaptor).
    To start - I plugged the monitor in with the thunderbolt adaptor, and it powers up and works fine. However, there is a nasty buzz coming from the speakers. I did some research and it looks like a simple ground loop issue. I did a bit of troubleshooting, and this is where things get weird.
    What I found is - If I unplug the MBox, the monitor loses signal from the computer (displaying ‘No Signal Detected!’). Further, if I keep the MBox plugged in, however unplug both the cables from the MBox to the speakers, the monitor loses signal. It doesn’t matter if the speakers are turned off, however they need to be plugged in (or the monitor loses signal). Weirder still, I can unplug the MBox, however the monitor will work if I plug in the speakers through my macs headphone jack.
    Simply put, the monitor only works if there is a direct connection between the computer, the speakers, and the power source.  What is going on here? Is the monitor grounding through the computer port, to the speakers (I don’t know how this works, is this possible?). Could it somehow be the cheap VGA adaptor I am using?
    Some other information:
    - Everything is plugged into the same multi-box for power. I have tried plugging things into separate sources, and the result is the same.
    - If I unplug the thunderbolt adaptor, then the speaker noise disappears straight away.
    - The ground noise doesn’t appear in my headphones, which are plugged into the MBox.
    Any information would be great – am I missing something here, or is this genuinely weird?

    Well, I went back into Best Buy to test on 3 other laptops (2 Asus, and their floor model for this Sony). It seems to be doing the same problem so at least I was able to rule out broken hardware issue on my particular laptop.
    Here's what I did to test:
    Since I couldn't really install Adobe Premiere on their machines, I used the DVIO software (http://www.carr-engineering.com/dvio.htm) and a 5 min clip I captured.  I transferred onto their machines, hooked up my Sony D8, and attempted to play the video.  It would play for 15 seconds and then stop and jitter with a loud noise (like it does on my laptop).  I even tried changing each machine's firewire driver to the legacy one and same results.  I pulled a brand new 4 pin to 4 pin firewire cable off their shelf and still the same problem.
    I think I've nailed it down to Win7x64 bit Home Edition not playing nice with Firewire driver.  Very annoying.  I can't find any concrete evidence of this from other users on any of the forums that have my particular problem, but from my own testing, it's all I can conclude.
    I have 2 other things I can try:
    1.  Opening the laptop and looking at the firewire to maybe find appropriate driver (ugh, I don't want to have to open this thing up).
    2.  Upgrading to Win7x64bit Pro and possibly testing with XP on the new MS Virtual PC (http://www.microsoft.com/windows/virtual-pc/).  I can't do it with my Home edition apparantly.
    Who needs to view video on an external TV anyways....sheeesh...(scarcasm).
