Lost sound driver after installing airparrot

I have a 2009 Macbook pro running mountain lion. I downloaded this program called Airparrot to stream my screen to my apple TV. While streaming it asked to download Airparrots sound drivers so I did. No im able to get sound on my TV while streaming and sound if I plug in headphones to the headphone jack but No sound trough my internal macbook speakers. If I go into system preferences there is no option for internal speakers.
I think when I installed Airparrots audio it deleted the internal speaker driver.
I tried restoring the system and still nothing
How do I get my internal speaker option back ??

  • Time Machine can't find external drive after installing Lion

    Time Machine can't find external drive after installing Lion. I have a Laice 1 terabyte external drive that worked fine with Snow Leopard and now no show ... tried connecting it to front port and Mac Pro can't see it. Also lost Office,Quicken, and Final Cut Pro  says: " You can't open application because Power PC apps are no longer supported" this is Not a good surprise!

    Does the drive work when just directly connected? If so, have you prepped the drive?
    Extended Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X 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 Installer menu (Utilities menu for Tiger or Leopard.)
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

  • HT3986 i installed win 7 on my mac book, and the sound driver was installed successfully, but i don't hear any sound, please help

    i installed win 7 on my mac book, and the sound driver was installed successfully, but i don't hear any sound, please help

    Is the volume muted? Click on the volume icon in the system tray to see if it shows as muted. If that's the case, I know of a workaround to fix this because if you unmute the speakers now, the condition will come back when you reboot your computer. I don't know the exact steps off the top of my head at the moment as I'm not in front of my machine. Check this first and reply if muting was the problem and I will detail the steps needed to fix the problem.

  • Sound Problem After Installing iOS 8.1

    Hello, after updating my iPad to iOS8.1 it started making weird noises, kind of the same ones you get while blocking it or getting a notification but with a little of a "robotic" twist. Restoring it seemed to had fix it until I tried to get the 8.1 again. I was just wondering if someone its having the same issue, and if so, whats the solution. Do you think that i'll be treated on the 8.2 version? I had the same problem with my iphone 4 once and couldnt get it sorted out.

    I successfully got my iPhone 6 messages sound by following Timothy Holt directions.
    Thanks Tim.

    What you have to do, and this appears to be essential after you update the OS, is to reboot your phone.
    1. Hold down the sleep/wake button and home button simultaneously.
    2. Let go when the Apple logo appears and the iPhone is booting up.

  • How come my mac isnt showing my external hard drive after installing os x maverick? and how to i fix that??

    how come my mac isnt showing my external hard drive after installing os x maverick? and how to i fix that??

    How do you mean it isn't showing the external drive?  If you mean on the desktop, click Finder on the menu bar, Preferences, General and check the boxes for Show these items on the desktop - make sure hard drives is checked.
    If you mean it is not showing in Finder or Disk Utility, make sure it is turned on, reboot and see if that mounts it so it shows up.

  • I lost sound shortly after iOS 6 was down loaded. Sound works headphones.

    I lost sound shortly after iOS 6 was down loaded. Sound works with headphones. When no headphones are plugged in and I try to use the volume control on side sound effects comes up but no sound is made. I get sound over main speaker when i adjust alert volume. I restarted and downloaded iOS 6 update with no results.

    Try this:
    1. Settings>General>Use Side-Switch To>Lock Rotation.
    2. Double-click the Home button and swipe Task Bar to the right.
    3. Make sure the button on the far left of Task Bar is not muted

  • Old videos lost their audio after installing iOS4

    My old videos lost their audio after installing iOS4.
    Quite frustrating. Any fix?
    (I am with iPhone 3GS).

    Do they still have audio in iTunes? Then, try using iTunes to "convert" them to iPhone-compatible format.

  • Satellite Pro L40 - Sound Driver after Windows XP SP3 Install

    Hi,
    I had bought the Satellite Pro L40 about 6 months ago and the speed of the laptop was too slow with windows Vista. So I decided to install an old copy of windows XP that I had bought earlier. I upgraded the windows installation to SP3 before installing all the drivers.
    Now all the drivers have been installed properly except the sound driver. I downloaded the XP version of the driver from the toshiba website but it did not work. So I though maybe the vista version would work, so I downloaded that. But that didn't work either.
    Can anyone suggest a solution where I can get the sound driver to work? Preferably without having to get the windows reinstalled again.
    Please help me out...!
    Thanks

    Regards,Tony

    No you can't use WMP to sync your iPod.
    You could take a look at Yamipod which allows you to manage your iPod without iTunes, but why not try and get iTunes working.

  • My computer sound is not working even the sound driver is installed

    HI,
    i'm using windows 7, my computer sound was working perfectly, recently i tried to update my sound driver using DRIVER BOOSTER, after the update there was no sound when i tried to play music an ERROR appears, then i uninstalled it, still not working, i went
    to DEVICE MANAGER, to check my SOUND DRIVER it says  '' This device is working properly.'' though i get no sound. 
    NB : my sound driver is 'Realtek high definition audio'.
    help me please.

    First you need to go find the correct driver for you computer. If it is a dell, or similar model go to the manufacturers website. If not then go to Realtek to download the proper driver by model number.
    Download the correct driver for your model soundcard.
    You need to uninstall your current sound card driver. restart your computer
    Upon restarting you can then install the proper driver by running the program you downloaded.
    P.S. Only get your drivers from the manufacturers, third party drivers, like Drivers Dot Com and many others are just BAD to put it nicely. They rarely have the correct ones and more often then not add extra programs to the driver packages.

  • No sound anymore after installing XP Home on Satellite Pro 4600

    Hi gents,
    I don't have any sound more after I have installed winxp home on my Pro 4600. I used the problem solve wizard but without any improvements. I have also installed the latest sound driver and bios.
    Looking forward to some replies, .............Harry

    He Eldorado,
    You teached me a wise lesson "first look to the obvious things". And yes it was the volume controller at the side (did not know there was one). But anyway problem is solved
    Thanks...........Harry

  • Why is there so much available space on my hard drive after installing Lion?

    I just made the decision to  go ahead and install the new operating system "Lion"
    I backed everything up to my Time Capsule and I have an older back up of everything on an external hard drive.
    Now I have two questions and one task.
    Why is there so much available space on my hard drive and where did my iPhoto library go after installing the new operating system?
    My task is to restore my most up to date iPhoto library which I assume is on my time capsule.
    How should I approach this task?

    Hi entresoft,
    I am not sure how to do this. I am not a very literate computer person but have a vague idea of what you are suggesting.
    If I do manage to figure out how to do what you have suggested will this restore my iPhoto Library and I assume maybe other files?
    Thanks!
