Hi,
Have you tried to enable the Speakers in Playback devices as follows:
1. Right click speaker icon (right hand corner)
2. Select Playback devices
3. Right click Speakers
4. Enable it and set as Default
5. Click Apply/Ok

  • Internal speakers not working after upgrading to Maverics

    internal speakers not working after upgrading to Maverics

    There are many possible causes for this issue. Take each of the following steps that you haven't already tried.
    1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
    2. Run Software Update and make sure you have a fully up-to-date installation of OS X.
    3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
    4. If you've installed a software equalizer called "Boom" or anything similar, update or delete it and restart.
    5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
    6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select the Output tab. If the Mute boxes are checked, uncheck them. Move the Volume sliders all the way to the right.
    7. If a red light is coming from the audio-out port, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by your warranty.
    If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
    8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
    9. If you have a MacBook Air, turn off Bluetooth and restart.
    10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
    11. Reset the NVRAM.
    12. Reset the SMC.
    13. Reinstall OS X after backing up all data.
    14. Make a "Genius" appointment at an Apple Store.

    When I unplug Apple headphones from my MacBook Pro sond from internal speakers not work, and system soud preferences displayed: Output: optical digital out port only

    If you see a red light in the audio output port, then the internal switch is stuck.  Insert the earphone plug a few times and see if you can trip the switch.  If that fails, insert a cocktail stirrer and the like and jiggle it around inside.  If that fails, take it to an Apple store and have the technicians at the genius bar do it for you.

    Hi,
    Try the following.
    Download the IDT Audio installer on the link below and save it to your Downloads folder.
    http://ftp.hp.com/pub/softpaq/sp45001-45500/sp45073.exe
    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, plug in the AC Adapter and start the notebook.
      When Windows has fully loaded.  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.

  • Headphone Jack Glowing Red, Internal Speakers Not Working...

    Hey, I have a 2.0GHz White MacBook (almost a week old), and I just recently came across this problem (this morning, actually). I usually have my MacBook connected to some external speakers through the headphone jack, the internal speakers are pretty terrible. Anyway, last night I left the computer on playing music as I fell asleep, this morning I woke up and the computer must have some how come unplugged from the AC power, as it was dead. I plugged it back in and everything was fine (I mean, it had to charge up, and the battery 'health' in iStat Pro was down to 93%, also not sure what this means... But everything else was fine). Then, I unplugged my external speakers and the jack was glowing red, I believe there's an LED inside. The internal speakers would then not work.
    I did a quick Google search and discovered that this problem had been experienced on MacBook Pros. Someone recommended plugging in a set of headphones, I did so and then unplugged them and the internal speakers worked for a moment. I plugged in the external speakers again, and they worked (and work) fine. The problem is with the internals, they don't work, and plugging in my headphones again has not solved the problem, and the light is still on when the jack is not occupied.
    Any ideas?
    [edit] As of this writing, they are currently working, after plugging in the headphones again and unplugging them, however, the light still blinks when I do this, and there is a bit of a hesitation between the headphone being unplugged and the internal speakers kicking in... (longer than normal, I know there was always a slight delay, but this is a few seconds of blinking light and no sound).

    you can fix this by "cleaning" the audio jack. the computer thinks that a digital output is connected. if you go to sound under system preferences, and it says digital output rather than internal speakers, then this is the problem.
    I used a tightly rolled up piece of toilet paper to clean the jack. I twisted it up, stuck it in the jack, and then moved it around for a while. the red light went off and my internal speakers started working. someone else used a toothpick.
    also, before i fixed this, i couldn't turn the volume up or down (unless i was using headphones) and the volume level screen that shows up on the screen had a circle with a line thru it...like the no smoking signs, but small and just under the volume bars.

  • Why the iPad internal speakers not working with some applications and key sound?

    My iPad1 ' internal speakers not fully functioning. It is working with music and video, YouTube , but not working with applications such as games.
    Also with key pad sound .
    Please help me in this regard.

    If you lose sounds for keyboard clicks, games or other apps, email notifications and other notifications, system sounds may have been muted.
    System sounds can be muted and controlled two different ways. The screen lock rotation can be controlled in the same manner as well.
    Settings>General>Use Side Switch to: Mute System sounds. If this option is selected, the switch on the side of the iPad above the volume rocker will mute system sounds.
    If you choose Lock Screen Rotation, then the switch locks the screen. If the screen is locked, you will see a lock icon in the upper right corner next to the battery indicator gauge.
    If you have the side switch set to lock screen rotation then the system sound control is in the task bar. Double tap the home button and in the task bar at the bottom, swipe all the way to the right. The speaker icon is all the way to the left. Tap on it and system sounds will return.
    If you have the side switch set to mute system sounds, then the screen lock rotation can be accessed via the task bar in the same manner as described above.
    This support article from Apple explains how the side switch works.

  • Ipod touch 4G problem--internal speakers not working.

    Ipod 4g internal speakers failing after one month. Ipod was "rebooted" which helped for a few hours, then restored, which helped for about 1-2 hours, each time internal speakers worked for a while then stopped, Now rebooting useless, I suspect that restoring it again will allow internal speakers to work, but that takes 2-3 hours.
    We can use the earphones via the jack, but want to use the internal speakers.
    Have the latest operating system (version 4.3.2), and exclusively sync with itunes on Mac platform.  3 other ipod touches (3rd gen) in house work perfectly. The sound is on, bluetooth is not enabled (no bluetooth devices in home anyway and have never set it up on this ipod touch).
    Any ideas besides spending 3 hours restoring each time the internal speakers fail?  I have used air to blow out the earphone jack but that didn't help either. One application (line up 2) correctly indicates when the earphone jack is used and when it is not in use.
    Will be getting a call from apple tomorrow, I suspect that will need a new ipod touch 4g.

    you've exhausted all of the troubleshooting steps then it really needs to be replaced if it's still within the warranty.

  • IPod 2nd Generation Internal Speakers Not Working - HELP PLEASE!

    A couple of days ago my ipod's internal speakers stopped working, the volume control dissapeared and no sound was coming out. Now, when i have my headphones in, music will be playing but every so often they will cut out and again, the volume control bar will dissapear. I then have to remove the headphones and put them back in. I've tried resetting the ipod and turning it on and off, no change.
    Any help to solve it please? or is this the end of my trusty ipod?
    Ashlee

    Welcome to the discussions,
    try to restore "as new ipod", don't use your backup to get your settings back to your ipod, it may contain the corrupt files causing this problem.
    Make sure you transferred your purchases and synced your contacts/calendars before you start.

  • Macbook air internal speakers not working

    My macbook air is nearly brand new, and suddenly the internal speakers are not working.  I have checked and it is not on mute, the speakers are turned up (F12), and I have shut down & restarted. Any suggestions on how to fix this?

    Hopefully one of these steps should solve the problem.
    1. System Preference > Sound > Output > Internal Speakers
        Highlight  Internal Speakers
        Make sure that Mute is not enabled.
    2. Remove the headphone.
        If you see red light in the headphone port, plug the headphone
        in and out of the port 5 or 6 times to flip the microswitch inside.
        Sound output may be stuck in the digital mode.
    3. Reset PRAM.  http://support.apple.com/kb/PH4405
    4. Reset SMC.     http://support.apple.com/kb/HT3964
        Choose the method for:
        "Resetting SMC on portables with a battery you should not remove on your own".
    5. Applications > Utilities > Audio MIDI Setup
        Audio Devices window
        Side Bar
        Click the Built-in Output.
        Under Mute any of the boxes checked? If so, uncheck it.

  • HELP! internal speakers not working

    Hi! I was using my headphones, and when i disconeccted them, i can't hear anything . I go to system preference-sound and this is what i see...
    There is not a red light in the headphone port.

    Use the program Audio Midi Setup and make sure that the internal speakers are selected as an output device.
    If that doesn't work you can reboot while holding down the option-command-p-r keys at the same time until you hear it cycle through a second time, hopefully followed by the start up chime. That will reset the PRAM.

  • Audio jack and internal speakers not working!

    So my internal speakers no onger work and when I put in my Apple iPhone earphones there is a high pitched sound and they become very hot to the touch. This happened when they were in my ear, not cool. I love my computer and I would hate to give it up for a German keyboard (I bought my computer in NYC and now I live in Switzerland) or not having it for an extended period of time. Comments? Suggestions? Help? Scheisse!

    hi neuroanatomist,
    thx for your suggestion
    I read about it, but it doesn't really work for me (or maybe I wasn't able to have it work)
    So there is no actual fix to this?

  • Internal Speakers not working on Equium A110-276

    Hi
    I bought this Equium A110-276 a few months ago. I understand that connecting external speakers disables the internal speakers automatically. I have been using external speakers for quite some time, but now when I disconnect them the internal speakers are not working anymore.
    Any ideas what I should do to get my internal speakers working again?
    Many thanks.

    Hi,
    usually the socket where you connect your external speakers uses a sprung metal contact to disconnect the built in speakers when the plug is pushed in. Removal of the plug from the external speakers should then allow the sprung contact to return to its normal position which will return power to the built in speakers.
    It is possible that the plug from the external speakers has bent the sprung contact so that it no longer completes the circuit for the built in speakers. You will need to dismantle you nnotebook to get access to the socket to check.
    You could ask your local authorised service partner to check for you so that you don't invalidate your warranty.
    regards,
