27" intel imac audio isn't working

I recently had my 27" intel imac logic board replaced.
But when i got it home i noticed that there was a start up sound but all other sounds were disabbled. Atleast they look disabled.
When i press the sound key(f12) there is a small icon indicating that there is no audio available. I thought that it might be some drivers they forgot to install, so i did a system update. still no sound.
My second guess is that they forgot to attach some sort of audio cable.
any advice would be much appreciated.

thanks for the reply.
unfortunetly under the Built-in Output, none of the mute boxes are checked.
the source is set to "digital out" which doesn't seem right, and there are no other options for source which also seems wrong.

  • My user account on my iMac G5 isn't working correctly?

    Hello all,
    I recently downloaded a program called "Secrets" on my iMac G5. This program tweaks some simple settings such as changing the dock from the glassy 3D to the 2D black dock. After tweaking a few things to what I thought would help my computer faster, I restarted it. Everything was working well, but when I logged in I noticed some issues. The top right part of the transparent bar wasn't loading. The bar itself was, but the time, ethernet icon, and bluetooth icon were not. I ignored this, as usualy it took a decent amount of time for it to load. However, then I tried launching Safari. The icon bounced as usual, but nothing happened at all. I tried loading system preferences, it clicked, but nothing happened at all. The same goes with everything else. Even attempting to click on shut down wouldn't work, it would just click and nothing would happen. I attempted to boot into safe mode, same results. I fimally found something that seemed to work, I logged into the guest account and from there, everything was working perfectly, which brought me down to thinking this is a user account related problem, probably because I installed that program "Secrets" on my main account only. Is there anything I could possibly try to get my main account working again? If not, is there some way I could transfer my programs from my old account to a new created one? (I tried, but I was told I didn't have sufficent permission to access my main account's "Applications" folder.)
    Thanks again for reading my problem, and I hope I could get some help.

    Hi Nick,
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • 27" iMac audio in not working or am I doing it wrong?

    Fortunately I am not experiencing any display issues on my quad-core iMac, yet... However, I am trying to use the audio-in port and seem to be having problems. When I input an audio signal (analog, like from an iPod headphone jack) I can see the "meter" bouncing in the Sound System Setting panel. However, I do not hear the music on the iMac's speakers.
    I do not see anything that says the port is digital only and I have the audio input and output set correctly. Is there something else that needs to be configured to hear the sounds on the iMacs's speakers?

    You will need a little app like Linein from Rogue Amoeba. It is a freebie!
    LineIn is a simple application for OS X to enable the soft playthru of audio from input devices. In simpler terms, you can use LineIn to play sound coming in through a microphone or any other device plugged in to your Sound In port, just as was once available with OS 9's "Play input through output device" option.

  • After installing Lion on a 2007 iMac, audio no longer works.

    All the audio options in System Preferences are greyed out. Message says no audio devices are detected. It's as if Lion can't see them. How do I restore audio?

    I am not sure any Mac every had a sound for plugging/unplugging USB devices.
    You may be right. It's only on Windows that the sound is created and heard.
    I know that since Tiger on this MBP, when I plug in my external scanner, I never heard anything.
    And plugging in my Blu-Ray recorder also does not make any sounds.
    I cannot speak for anything but my Mac laptops, however. Desktop Macs might make a sound.

  • My macbook's audio isn't working.

    If I turn up the volume, all I can hear is a loud buzzing sound. It does it with headphones too. I have no idea what to do or what could be wrong with it. I give online music lessons via skype, so I need to fix it asap. Any help would be much appreciated.

  • Intel iMac + USB Printer

    Hi,
    My HP Deskjet 845c Printer no longer works with my new intel iMac.
    (previously it did work with Powerbook G4 1.67, also running 10.4.6)
    I checked the Apple support document :
    http://docs.info.apple.com/article.html?artnum=303057
    for printers supported with intel macs & this printer IS listed as supported.
    I've also followed the steps described, including reseting the print manager.
    I AM able to print a test page, using the HP Driver utility via Printer Setup Utility.
    This works fine.
    However, if I attempt to print anything else (textedit, photoshop, preview) i get a badly garbled printout, letters large or streched & broken up onto several pages.
    I'm confused why the test page works fine from Printer Setup, but anything else is junk - Any ideas?

    it has the lastest drivers for the HP printers, yours included. I hope it'll work.

  • Intel Imac Unexpectedly shuts down...

    I work for a company that has bought several Intel Imacs and most are working fine, but we have two that while the user is working will just immediately power off, and then start back up (I have configured energy saver to restart on power failure). Both of the troublesome machines (like all the computers here) are running on UPS boxes, so we are not having an issue with power.
    Both macs have been fully updated with OS X 10.4.9 and all other system updates.
    Are there a string of bad power supplies that are causing this issue, or is it potentially something else? These machines were just installed in the last week. Any help will be greatly appreciated.

    Next you should check the ram modules as one or both modules may have become disloged during shipping. Use this article to help you reinstall the ram.
    http://docs.info.apple.com/article.html?artnum=303084
    If your handy with a screwdriver you can do this your self! Make sure that you reinstall both modules pressing firmly and seating them into place then close the two plastic eject levers and replace the cover. If this does not solve the issue I would give Apple a call. There has been a few reports of power supply issues but as you know Apple will make then good or replace them!

One 1/8" circle at bottom right and a tiny circle at top right.  The fading on and off light on area surrounding the screen isn't working anymore either.  Has anyone else had similar problems?  Any solutions?  Thanks!

  • Emagic mt4 and intel iMac does not work with 10.4.5

    Hi there,
    after updating my iMac on 10.4.5 my MT4 does not work any longer. It is still shown in the system profiler! But that`s it! After I`ve installed the latest driver (emagic v1.7), it was not shown in the audio/midi preferences. On my G4 with 10.3.9 it is still working properly. I have tried to use it with Garage Band 3, while I am waiting for Logic Pro 7.2 . It worked in the begining, but now the USB connection on the MT4 does not light up, but the midi devices. My question is: Do I need a driver using Logic Pro 7.2 with an Intel iMac? Includes the update the driver for Emagic MT4?
    thanks a lot for any reply, experiences and clues

    Hi Glyn,
    I will try to get some driver information of apple. Emagic is apple now, so who else could that know?! I use an m-audio fw audio-interface. For that m-audio got a driver and it works by now. Fortunately! I will tell you if apple got a clue.
    Thanks for reply ( So I am not the only one in universe with that problem!)

  • Has anyone got HK iSub v1. to work with Intel iMac?

    System preferences does not see the device at all. Have tried different ports with and without USB hubs both through a Series 1.0 and Series 2.0 with no luck. Any suggestions? Or is it time to retire the thing? Pity though it sounds great and still looks good!
    Any advice appreciated.

    I had the same problem and got it straightened out at the local Genius Bar! Did you transfer your folders from a previous Mac on your Intel iMac? The prefs transferred over too and may be corrupt.
    1) Create a new user and give it admin privledges
    2) Under "Library", drag and drop the Audio (which may not be necessary) and Preference folders onto desktop.
    Log out and restart.
    Log back in as yourself and let it fly! By dragging the Prefs folder onto desktop, at restart your iMac rebuilds the Prefs and overwrites previous corrupted Prefs.
    Now I need to figure out why my Sony CyberShot isn't recognized on my USBs! Maddening!

  • Intel IMac sometimes don't launch Audio Instrum

    Hi!
    Recently I purchased a Intel IMac 1.8 and an M Audio Midi One interface. As it's a very new machine, I decided to install the OS using the DVDs that came with the IMac, and then search for the upgrades at apple. Well, after installing everything, including LP7.2 full version and LP7.2.1 upgrade, I've noticied that sometimes some audio instruments don't launch, and when I try to close the project, logic crashes. Does anyone know something about it? I'm trying to work mainly with audio instruments, and I really can't get a job.

    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

  • Intel iMac sound only works out of one speaker, but both headphones...

    Hello.
       I've run into a very interesting problem with the sound of my 20" Intel iMac's sound. Ever since I moved into my new appartment, my Logitech computer speakers have only worked out of the left speaker. The strange bit is that if I plug any pair of headphones into the same jack I get perfect sterio sound. I've check my sound preferences to make sure the sound is balanced, checked multiple pairs of headphones (that are all known to work perfectly), multiple pairs of computer speakers (that are all known to work perfectly), I even plugged in my M-Audio fast track USB audio interface with the same results (left channel only with speakers, sterio with headphones) Another weird thing is that I tested both pairs of computer speakers with my roommate's 20" Intel iMac (same model) and both worked just fine.
      I feel like I've run the gambit of things I could do to eliminate a faulty component. Do you think I have a faulty jack? something wrong with my software/hardware? I'm completely stumpped...anyone have any ideas?

    You've done a lot of testing such that it sounds like the jack and plug combination of the Logitechs and the iMac are just a hair short now, and the move is the only thing that changed. Can you compare the headphone plug and the Logitech plug side by side for length? Is one of them a straight plug and the other a 90 degree such that it can't get all the way in now? I'm sure you've tried pushing it in extra hard or wiggling a bit. One guy on here awhile back sent pix of his headphone port and the one right beside it on the back of his iMac, and the headphone one was recessed slightly deeper into the iMac's body.

  • Periodic iChat audio dropouts over Airport on Intel iMac

    When chatting with iChat, an audio dropout occurs exactly every 5 minutes on my new Intel iMac. iChat's Connection Doctor shows total loss of receive audio signal quality (and a halving of the receive bit rate) for about 5-10 seconds. Then normal operation resumes for 5 minutes and the problem repeats. This only occurs while using iChat over Airport. I can also force this audio dropout behavior at any time by clicking on the Airport status icon on the menubar. I wonder if others are having this problem or is this an isolated problem with my computer?
    It took me a while to recognize that this wasn't a network problem causing occasional audio dropouts. My wireless D-Link router isn't the culprit as my G4 iMac and G3 laptop don't exhibit the problem through the router. Also, when connecting from the Intel iMac to any of the other nearby Macs using a computer to computer Bonjour wireless connection (thus eliminating the router) the dropouts do occur. After connecting, the dropout always occurs at a random time between 0 and 5 minutes but thereafter it occurs at exactly 5 minute intervals. If I click on the Airport status icon to force the audio dropout, the next dropout will occur 5 minutes later.
    I also have a new Intel Mac Mini which doesn't exhibit the periodic audio dropout problem but does have a similar audio dropout whenever I click on the Airport status icon. The dropout lasts longer on the Mini - about 15 seconds average before the audio signal quality fully recovers. Because the periodic dropout doesn't happen on the Mini, it isn't really an operational problem, but it is instructive to note that only the Intel Macs exhibit this particular behavior.
    In troubleshooting the iMac, I have turned off all timing related items that I can think of including, Mail (check manually), Set Date and Time Automatically (OFF), all sleep, hard drive and screen timers OFF, all iCal reminders OFF, etc. I have also turned all Dashboard Widgets OFF, corrected permissions, tried a different user ID, reset the NVRAM and SMC. I have even tried setting the iChat app to open as a Rosetta app . Nothing has solved this problem yet.
    The iMac is a dual core 20" with 1.5 GB of RAM and the Mini is a dual core with 512 MB of RAM. Both are running Tiger 10.4.5 Wireless signal level in all tests is 100 percent.
    Thanks for any help.

    OK, I have my Intel iMac connected to the Internet via an Ethernet converter. What this means is that the iMac is connected via Ethernet cable to the Ethernet converter, which, in turn, communicates wirelessly with a wireless router.
    This seems to clearly solve the wireless connection audio issue as the Intel iMac thinks it has only an Ethernet connection. There is no audio dropout after five minutes or so, but there may be other Mac to Mac connection issues related to Intel Macs.
    I'm going to run with this connection for awhile to see if there are other problems, but this seems to be a good workaround for the moment. I'm using a Buffalo Technology WLI-TX4-G54HP Ethernet converter, which costs about $60 USD at most online vendors in the US.
    Although $60 may seem like a lot of money to spend on an Apple-created problem, using the Buffalo high power device is almost surely going to provide significantly better wireless range. This increased range advantage may be enough to offset a large part or all of the $60 cost.
