IMac - External USB Speakers

Why does new iMac not recognize external usb speakers when connected to the back of the unit.  It only recognizes them when connected to a usb hub or the additional usb ports on the wired keyboard?  I'm receiving distortion from dac which I suspect is due to low signal strength.

there is no such thing as usb speakers
all usb speakers being that usb don¨'t carry audio at all
are usb audio cards usb audio cards require drivers if the usb audio card model you own does not have
drivers included in Mavericks you need to install the drivers from the usb audio card makers site if they does not
support Mavericks with their drivers your speakers will not work

  • System preferences -Sound does not see external USB speakers

    The computer internal speakers are working OK but the problems come when I try to use external USB speakers. The previous volume problem of the imnternal speakers resolved itself.
    I have now purchased a new USB set of speakers (BOSE Companion 20) but now they will only work through the "headphone" slot at the rear of my Imac and then only thru one speaker.(right)
    I have reset the PRAM - anyway I followed all the instructions and it was not solved.
    In "Sounds" in system preferences the Imac cannot see the USB speakers - it only recognises the internal speakers for output.
    I think until "sounds" recognises the USB Speakers I will not get both speakers working.
    I insert the USB speaker wiring pin in the Headphones slot at the back of the Imac and as mentioned sound only comes thru the right USB speaker  -nothing works when I put the pin in the speakers slot alongside the Headphones slot.
    Any help apprecaited

  • Crackling and pulsating noise in external USB speakers

    How to eliminate crackling and pulsating noise in external USB speakers?

    i need to access the Roland's knobs while sitting at the Mac (am using them as monitors in recording etc), so there really isn't a good place to get them further away. By interface, do you mean the PreMobile? that's an interesting idea. I've now tried that (via the line out, the rolands have a single 3.5mm cable, no RCAs); it got rid of the static noise, but the still a loud hum, and the PreMobile apparently doesn't monitor ordinary system sound output (like iTunes). But this experiment does point to the iMac itself being the source of the static noise.
    The only AC-powered periphs in the loop are a couple hard drives and a printer (and a USB-powered Wacom tablet; the PreMobile is USB-powered as well).
    I've got the speakers plugged into same grounded strip as the mac and the peripherals, trying to minimize ground loop, but it doesn't help.
    Someone suggested a ground loop isolator gadget... anyone had success with those?

  • External USB Speakers Unrecognized After 10.5.2

    After installing the 10.5.2 update, my USB speakers (Logitech Z-10) are no longer recognized. I've unplugged them, logged in and out, and restarted multiple times.
    Is anyone else experiencing this or does any have suggestions?

    Where they plugged in when you ran the update? If they were, it's possible the driver was in use and couldn't be replaced. Can you unplug them and re-install the 10.5.2 update?

  • Connecting USB Speakers to 2013 iMac without Airplay?

    Have new 27" iMac (Intel i5 May 2013 build) and find no way to hook up external USB speakers.  System's preferences offers no external opiton beyond Airplay which I hope to avoid.  I don't know the distinction between USB 2 and USB 3, but wonder if my two year old speakers have an older version of USB connection and whether it will work.  Thanks for any help with this newbie question. 

    Thanks, BD.  I've been reading about target disk mode which sounds like it might be an appropriate solution for getting my photos and music to the new iMac.  If I understand it, it sounds like I would connect the old MBP to the new iMac with a Firewire 800 cable (with Thunderbolt adapter for the iMac).  The iMac would be running while the old MBP would be started up in Target Mode -- either by holding the T key while booting, or by restarting after selecting the Systems Disk in System Preferences>Mac HD>Restart.  The target MBP should come up in Target Mode and mount in the Finder on the iMac.  This should allow copying the iTunes Files from the MBP to iTunes on the iMac.  Similarly I've read this would enable me also to copy the iPhoto Library from the Pictures Folder of the MBP to the Pictures Folder of the iMac.  I'm nervous about whether copying is a simple drag-and-drop, or perhaps a multistage process that requires knowing where precisely to place the new files.  The process on the iTunes seems critical since I'm moving 125 GB.  Still, the concept seems like it might be relatively straight forward as long as I don't get confused about which computer is which, and whether I am dealing with the files themselves or the whole Library folder.  In the case of iPhoto, I believe I'm copying the whole Library from Pictures on MBP to Pictures on iMac.  On the iTunes, I'm not sure if I'm copying the files into the iMac iTunes, or simply copying the Library from MBP Music to iMac Music.  If you have any insight on Target Mode, it might help me decide whether that's the way to go.  Thanks for your replies.  It's nice to know someone out there actually understands this stuff.  Best, Dean

  • Samson Studio GT USB Speakers no longer recognized

    All,
    I have 2 MacBooks with Yosemite on them.  I have the Studio GT external USB speakers.  Now, what seems to be randomly, the speakers are not visible in system preferences under sound.  I follow the mfg instructions of, plug them into the wall, plug in the usb, turn them on.  The mac will recognize them.  This use to work but no longer.  Now, when I do that, there is nothing int he system preferences.  The power light is on the speaker and they have an input for a mic.  If I use the mic, the sound comes out of the speakers so I know the speakers work.  Also, since these do not work on both MacBooks, but did in the past, has me suspicious.  Both MacBooks are running Yosemite 10.10.2.  Not only is it not displayed in system preferences / sound but its not displayed in the system report.  Nothing appears to be plugged into the USB port but the speakers are.
    Any help is appreciated!!!!
    Thanks in advance.

    Hey there W_Ray,
    It sounds like these USB speakers aren't working correclty on either of 2 computers, not even if you power cycle them. Normally that would indicate an issue with the speakers themselves, but if you would like to, you can try troubleshooting for USB issues on one or both of the Macs with this article:
    OS X Yosemite: If a USB device isn’t working
    Check power and cables: 
    Make sure the USB device is turned on and its cables are properly connected.
    Check for missing software: 
    Make sure you installed the latest software for your device. Visit the manufacturer’s website for any updates.
    If the device is connected to a USB hub: 
    Make sure the device and the hub are the same speed. Connect USB 3.0 SuperSpeed devices to a USB 3.0 SuperSpeed HUB, USB 2.0 Hi-Speed devices to a USB 2.0 Hi-Speed hub, and so on. 
    If the device doesn’t have a power cord and is plugged into another USB device that doesn’t have a power cord: 
    Try plugging the device directly into your computer’s USB port  or into a USB device that does have a power cord. You might need to disconnect and reconnect the other device as well, if it has stopped responding. 
    If you have many devices connected to your Mac: 
    Disconnect all USB devices except the device you’re testing, an Apple keyboard, and an Apple mouse. Make sure that the device is connected directly to the computer, and that any hubs or extension cables are disconnected. If you can use the device now, the problem may be with one of the other USB devices or hubs you had connected to your computer. Try reconnecting them, one by one, to your computer. When you find the device causing the problem, review its documentation for further troubleshooting steps. 
    Verify that the device appears in System Information: 
    Choose Apple menu > About This Mac. In the window that appears, click Overview, then click the System Report button to open System Information. 
    In the window that appears, see if the USB device is listed below Hardware in the Contents list. If the device appears but does not work, review the device’s documentation for further troubleshooting steps. 
    Restart apps: 
    Quit and restart any apps that use the device. 
    Restart your Mac: 
    Choose Apple menu > Restart.
    Thank you for using Apple Support Communities.
    Take care,

  • Brand new iMacs & an external USB drive disappeared on one of them - help?

    I'm new to this particular forum & I just bought a 2.8 GHz intel iMac (my wife is picking up for me this moment) - my boss just bought a 3.06 GHz intel iMac a few days ago, he installed Parallels & then Vista Ultimate w/SP1. He has an external USB hard drive & it showed up mounted on the desktop. When Vista asked him (voices from the dark side) if he wanted to link the drive to Vista he said yes - that's when the drive disappeared & he said that he couldn't get it back & he said that he couldn't find it with the explorer in Vista either. He tried rebooting, tried reconnecting the drive, doing this w/o launching Vista, etc - but he said that it wouldn't come back. He is not experienced with Macs, only the dark side so he's not familar with the system yet. I have not seen his Mac yet. I'm at work, so I do not have access to a Mac, I cannot offer troubleshooting tips for this cold turkey w/o a Mac in front of me, as it has been over 5 years since I've seen a problem like this.
    That is why I'm writing this here, because I know that this is no doubt a simple fix for most of you. I can try to get him to come to this discussions site.
    I can't wait to fly my new Mac today - should I just go ahead and re-format (low-level) & install from scratch? Even though I've purchased Parallels also, which needs no partition, should I make a partition anyway, incase i want to also use the Boot Camp route on the other partition?
    Thanks 1.0E6,
    Gino

    Success - He finally did get it back after shutting everything down, powering down, pulling its connection, bring the mac back up sans Parallels/Vista, connect up the drive, drive showed back up, then startup Parallels/Vista.
    btw - my new iMac is a dream (2.8/500/24") - I changed the memory to 4 mb, low level formatted the Mac, installed the software & "wow-zer" compared to my older lapstand iMac
    btw2 - I had posted before to other forums (Airport, Mail), but this was the 1st time to this particular forum (intel iMac)

  • On 2011 iMac, External Altec Lansing speakers no longer work after upgrading to Mountain Lion. They DO work on a lenovo machine but not my imac

    On 2011 iMac, External Altec Lansing speakers no longer work after upgrading to Mountain Lion.
    They DO work on a lenovo machine but not my iMac. reset Pram - no luck. took speakers from wife's desktop, they
    do not work when jack plugged into my iMac - Sys Prefs "SOUND" only lists "internal speakers/ built in" as available options.
    I used my altec lansing speakers on 3 macs including this one for 5-6 years.....now with Mountian Lion I can only get internal speakers???
    Ideas? Any/All help would be greatly appreciated - been going nuts with this for 2 days now.

    Hi,
    When you start Messages fro the first time you are asked for an Apple ID
    When this is verified and entered it appears in Messages Menu > Preference > Accounts and is Enabled.
    The App should have also picked on on those iChat Accounst you had before.
    These should be Enabled if they were when you last used iChat.
    Exactly which "Accounts" are logged in can be seen in Message Menu > Accounts and will include the iMessage "Account" and Bonjour.
    In the Window menu you will see CMD +0 for the Messages window and CMD+1 for the "Buddies" window which is a combined list at this stage.
    Go to the Preferences > General Section and Untick the "Collect all accounts into one list".
    This will give you separate iChat type Buddy lists.
    You can check if that account/Buddy list is set to Invisible or if in the Preferences > Accounts > Security you have settings that will block some people from seeing you as On line.
    You are saying Buddies can see you as On Line which implies they are still sending to your AIM based Names (@Mac.com is a valid AIM Screen Name)
    I am not sure from your post if you are trying to iMessage their email IDs thinking they are Apple IDs and that they are using Messages as well.
    There is no Buddy list for iMessages side
    No-one can tell you are "On Line" until they have your details in the "To" spot in Messages with the correct iMessaged contact info (iPhone Number or Apple ID)
    Obviously an Apple ID can be an email or look like one.
    In some cases they are also valid AIM Screen Names as well.
    In the case or the @mac.com name you may have linked this Apple ID to iMessages as well.

  • 2.5" external USB hard drive not recognized by my iMac

    I have a small 2.5" external USB hard drive that my intel iMac will not mount or see. My 12" G4 Powerbook sees it fine and it is formatted in Mac OS Extended. My iMac is bootcamped and XP on my iMac sees the drive but not OS X Tiger on the iMac, (wierd) I have Tiger on both my Macs too.
    Why does the intel based OS X refuse to see this external 2.5 HD. It sees a 3.5" USB one I have but not the small one. I know it is software.

    Hey coby,
    Well thanks for the star. Not sure I deserve it.
    i then tried connecting the drive to each USB port again, and voila! i have found one it works in. I guess my computer's ports must be a little worn.
    Hmm well try looking inside and see if there's some smutz in there, if the contacts are dirty or bent or worn.
    i was starting to think i would have to go out and get a USB hub to give it some more power.
    Is it powered off the USB? If so that actually might be a good idea since that puts a lot of strain on the connectors. Even if it's self powered it might be a good idea since it would take the strain off an obviously flakey USB.

  • Can I use an external usb super drive on my iMac 10.6.8 ?

    Can I use an external USB SuperDrive on my 10.6.8 iMac the internal drive is not working at all? Thank you.

    The answer is no unless you are willing to modify a system file.  See this article.  Read the entire thing and the comments before deciding if it is the route for you.
    If it were me I'd go with Shootist's advice and get another brand--for the reasons he stated.
    I have a SuperDrive that I use with my 2012 MBA but with my late-2012 27" iMac, which does not have an internal CD/DVD drive and therefore will work with the SuperDrive, I use a 3rd party that is both faster and cheaper than the SuperDrive.

  • I want to dual boot Windows 8 on my 20-inch, Mid 2007 iMac, from an external USB drive.

    I want to dual boot Windows 8 on my 20-inch, Mid 2007 iMac, from an external USB drive. The internal drive is completely dead, it doesn't even show up in Disk Utility.  I'm running 10.8.2 from the external drive.  When I start Boot Camp Assistant, at the Introduction page, when I press the continue button nothing happens.  Do I have to have internal drive to run Boot Camp Assistant?  Can anyone provide me with the steps to dual boot, with his setup?  Thanks in advance!

    Hi maczimillon,
    Only follow these steps, it works for my:
    Open "System Information" and note your "Boot ROM Version" (some like MBP51.007E.B06)
    Navigate to "Utilities" in Finder and open the package contents of -BootCampAssistant.app- with right click. Duplicate the "Info.plist" file to the Desktop e.g. and open that with Text Editor.
    You must locate the keys "DARequiredROMVersions"and "USBBootSupportedModels"
    Add new strings with the information of your machine under booth keys (step 1), always respect the format, such as: <string>MBP51.007E.B06</string> for the frist key and <string>MBP51</string> for the second key.
    Save changes and replace the original plist file (it may ask you to enter admin pass)
    If you proceeded correctly you will see the checkbox "Create a Windows 7 USB install disk" enabled in Boot Camp Assistant.
    Then you can follow the usual Boot Camp installation using your WIN8 DVD iso image . The assistant program will proceed resizing your disk partition and installing necessary drivers for your iMac.
    I strongly recomends you to use thirld party's bootloaders like rEFInd (rEFIt) because of the Apple SMC versions of some old machines should not be able to boot properly from external devices like USB drives.

  • HT4889 Migration Assistant to update my new Mountain Lion iMac from an external USB hard disk drive, it is constantly saying that it is "looking for other computers". It doesn't find the external drive. Why is it looking for other computers?

    I'm trying to use Migration Assistant to update my new Mountain Lion iMac from an external USB hard disk drive. I told it to look for a drive, yet it is constantly saying that it is "looking for other computers". It doesn't find the external drive ... it just endlessly looks for other computers. Why is it looking for other computers at all, when I told it not to?

    Wow, the wording in Migration Assistant is misleading. I've never used it before, so I thought I would try to copy my files from the external drive ... my old iMac died, but I managed to get everything I need off it, using the 'cp' command in single-user mode. So I guess I'll just have to manually copy the files from the external drive to the new machine. I was hoping that Migration Assistant might help somehow, but obviously not.
    Thanks for the quick reply!

  • Will my imac superdrive work ok if i put it in an external usb enclosure?

    Hi!
    I have an optibay caddy to put in my iMac 27" so I can add a second SSD to my system... Question... Will OSX still recognise the superdrive and use it as normal if i put it in a slot loading external USB caddy?
    Thanks for any advice in advance.
    Mike

    It may. It could. It should in theory. But none of us can guarantee it will. You will just need to give it a try. I would get a caddy that is guaranteed by its developer to work with a Mac.
    Update -
    Looking on the Optibay site, I see that they include a caddy for your Superdrive, with the Optibay, to do exactly this solution. So that should definitely work for you. They have developed it to do so.

  • IMAC won't start with external USB drive

    I've been running Leopard for a few weeks now and decided to connect an external USB hard drive to use with Time Machine, it did the backup fine and seems to be working fine... however, every time I start my imac in the morning I get a gray screen that just hangs. I have to unplug the USB drive then reboot again.. that salves the problem.. but is annoying to have to do that each time.. I also noticed today that my ipod when plugger in via USB will not mount on the desktop.. I have to unplug the USB hard drive then plug the ipod in again.. that solves the problem..
    Anyone have this same issue..??? It seems to be USB related or Time Machine related.. maybe both..
    Cheers

    The Disks are formatted with Ntfs as i am using Bootcamp with Windows 7. So repairing disks would not work in Mac OSX, and is not needed as the disks are ok. I would be a strange coincidence that both disks would be corrupted at the same Time.
    I have tried three different other USB disks in the meantime and the Macbook could Boot up everytime with no problem. I found the answer in another forum. The controllers (USB to SATA) in the enclosures of the disks are not compatible with my Macbook, they are rather cheap WD disks and a lot of other users reported the same problem. ist might be possible to upgrade the firmware, but i will rather look for some other disks and try them first before i buy.
