Lost all sound to imac

Was having intermittent sound issues with iMac prior and after a while, there is no more sound. Hardware profile does not show any sound hardware. Garageband says missine core audio drivers. Any idea?

Well it could be a number of things. We really need more information to be able to help:
- What system are you running?
- Which version of osx are you running?
- Have you got the latest updates?
- Do the cron scripts run regularly?
- Have you tried repairing premissions?
- Have you run the hardware checker on the os x dvd1?
- Have you run the disc checker on that cd?
- How long has the problem been there?
This should help the folks on here to help you more.

  • Lost all sounds on Imac can not deselect mute all computer sounds

    I can not deselect mute all computer sounds on my Imac with Lion I went into preference and for output the only thing I can select is headphones is there away to get the built in speakers back on this drop down list?

    Hello, long shot, but...
    Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there, some things will change it for their own use, then not set it back

  • I have a HP Pavilion dv7-1444 running Vista 64 bit. I have lost all sound.

    I have a HP Pavilion dv7-1444 running Windows Vista 64 bit. I have lost all sound. There's a red x next to the speakeer icon on the bottom right of the screen. I have reloaded drivers, checked Device Manager, tested sounds, HP Support Assistant says I have the latest BIOS installed. I tried a one prong earphone in the two prong headset and got no sound. The mute button and the volume slider don't work either. 
    Please help me if you can.

  • Lost all sound on my HP Pavilion dv6 notebook

    I have a HP Pavillion dv6 notebook with a Widows 7 operating system and have lost all sound. Any suggestions as this is a 6 month old notebook?

    I had the same issue last night after an automatic BIOS update.  I read about 7 pages of posts that seem to deal with the same issue and found a combination of actions that seem to have restored my audio functions completely.  I posted the solution and it resolved the issue for at least one other user who commented back.  It it works for you, please also post that it worked for you.  I suspect there are alot of users out there that have or will be experiencing the same issue.  It would be nice if HP would post the appropriate solution, it seems to have been going on for awhile.
    1. Through 'Device Manager / Sound, video and game controller' I uninstalled my audio driver (IDT High Definition CODEC) and also deleted the driver software for the device.
    2. Through 'Programs and Features' I uninstalled the IDT Audio Software (vers 1.0.6418.0) that was installed with the BIOS update.
    --> This forced a reboot.
    --> When my system rebooted it automatically searched and found the appropriate audio driver -- now I've got audio and Media Center works fine...
    Hope this helps you.

  • TS1702 I lost all sound in my game apps why?

    I lost all sound on all my game apps why?

    Hi,
    Try the following.
    Download the IDT Audio installer on the link below and save it to your Downloads folder.
    IDT Audio Installer - Windows 7.
    When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers.  Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
    When complete, shut down the notebook, unplug the AC Adapter and then remove the battery.  Hold  down the Power button for 30 seconds.  Re-insert the battery and plug in the AC Adapter.
    Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu.  Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter.  Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
    Let Windows fully load - it will automatically load an audio driver, but just let this complete.  Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation.  When this has completed, right click the speaker icon in the Taskbar and select Playback Devices.  Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.

  • HT3986 Lost All Sound in windows 7 on my macbook air

    Well, recently i just installed windows 7 on my mac using bootcamp, but i lost all sound on windows (works on OSX), and the "f"  keys dont work.. (f1-f12)
    What could i do for this :O ?

    As this is almost a daily question, take a look at other threads.
    See what audio chip you have in Device Manager, then find - download - manually install that after you have installed the Apple drivers.

    Have you got notifications muted ? Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

  • Lost all sound on Windows 8

    i have lost all sound on W8. hvae checked plugins and they are all up to date. have never had good sound on this computer (Pacbell Easynote TE) anyway and am considering getting speakers. However i recently downloaded Windows Movie Maker as was having problems with videos taken on my phone that were taking long time to attach on e-mail (i have gmail), if they semed to big for normal 'attachment' . Have also started using their (gmail) Google drive to see if that would help speed things up, but didn't, so tried to load Cloud etc. I think that somewhere in all this the sound went, but it's a minefield (for me anyway) to try and work out. I have done the obvious and checked the Volume levels and they're all supposedly on and set at highest. Any help greatly appreciated. thanks

    Wellthis is strange, i have now checked the videos i mentioned above and now have sound, be it all very low, but that has always been the case with this pacbell since i got it. Also checked some others on Facebook and they have sound too - why would that change overnight??
