I have a HP Pavilion dv6 that has suddenly stopped playing any kind of audio. How do I fix this?

I have a HP Pavilion dv6 that suddenly stopped playing any kind of sound.  That's with earphones plugged in or not.  The microphone indicator in sound setup indicates that it is listening to external sound, and when I play system sounds, the speaker icon in the volume mixer indicates that the hardware thinks it is playing sounds, but nothing is coming out of the laptop at all.  I thought if it were a speaker not working internally I could fix it with earphones or external speaker but that isn't working either.  
Any ideas?

Hi,
Try the following.
Open windows Control Panel, open Windows Update, select 'View update history' in the left hand pane and then select 'Installed updates' link in the following window.
Locate update KB2962407, right click it and select Uninstall.  When done, restart the notebook, open windows Control Panel, open Windows Update and select 'Check for updates'.  You'll see the update you just uninstalled being offered again - right click and select 'Hide Update'.
After this you may or may not need to delete and reload the Audio driver - if you do, the procedure for using recovery manager to reinstall Software and Drivers is detailed in the relevant document on the link below.
Recovery Manager - Windows 8.
Recovery Manager - Windows 7

    This has nothing to do with your pictures. As long as LR works, nothing happens. The CC app merely has lost an entry in the installer database. Would a reinstall fix it? Sure. Is it necessary? Not really (until the next version or update). So unless you have too much time to spend or something isn't working, I'm sure you can find more interesting things to do with your tiem. Otherwise use the cleaner tool and get to it:

    If it is the same app for the iPod and the iPad (universal or iPod/iPhone app) and not a iPad only app, the only way is to restore the iPad from the backup of the iPod.  That will wipe out all the app data currently on the iPad though.
    If the iPad is an iPad only app, then there is no way.

  • My Mac has suddenly stopped playing my DVDs including a DVD it played fine only 3 days ago. Does anyone have any idea what could be wrong and how I could fix it? Thank you.

    My Mac has suddenly stopped playing my DVDs including a DVD it played fine only 3 days ago. I insert the DVD and wait for the player to start automatically but after 10 minutes, nothing is happening and it sounds like the disk has stopped spinning. I've now tried with four different DVDs (all store bought and so perfectly normal disks). The Mac doesn't eject the disk or anything it just doesn't seem to respond to it being there at all.
    My main confusion is why this suddenly happened today when it was perfectly fine last week.
    Does anyone have any idea what could be wrong and how I could fix it? Thank you.

    Reader XI has suddenly stopped loading any images in pdf's.  Any idea why?

    I tried to got to edit to follow the suggestion of ~graffiti I found that the "Show Large Images" was already checked.  I since have found that if I download the .pdf file and then open the download everything appears as it should.  Previously, when I clicked on the emailed .pdf file it would automatically open without having to download the file.  I'm not sure why it is requiring the extra steps of downloading the and then opening the downloaded file before the images with appear.  Any ideas why the extra steps are now required?

    Hi Will555uk,
    Thanks for visiting Apple Support Communities.
    If your iPhone is restarting unexpectedly, I recommend starting with step three in this troubleshooting guide:
    iPhone: Hardware troubleshooting
    http://support.apple.com/kb/TS2802
    Will not turn on, will not turn on unless connected to power, or unexpected power off
    Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
    Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    After at least 30 minutes, if:
    The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
    The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
    Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
    If the display turns on, go to step 4.
    If the display remains black, go to next step.
    Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
    If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
    Best,
    Jeremy

  • HT201210 I am trying to update my ipad 2 but it keeps telling me that it isn't eligible for the requested build how can i fix this problem

    I am trying to update my ipad 2 but it keeps telling me that it isn't eligible for the requested build how can i fix this problem

    This device is not eligible for the requested build (Also sometimes displayed as an "error 3194")
    Update to the latest version of iTunes.
    Third-party security software or router security settings can also cause this issue. To resolve this, followTroubleshooting security software issues.
    Downgrading to a previous version of iOS is not supported. If you have installed software to perform unauthorized modifications to your iOS device, that software may have redirected connections to the update server (gs.apple.com) within the Hosts file. Uninstall the unauthorized modification software from the computer.
    Edit out the "gs.apple.com" redirect from your hosts file, and then restart the computer for the host file changes to take affect. For steps to edit the Hosts file and allow iTunes to communicate with the update server, see iTunes: Troubleshooting iTunes Store on your computer, iPhone, iPad, or iPod—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > The hosts file may also be blocking the iTunes Store. If you do not uninstall the unauthorized modification software prior to editing the hosts file, that software may automatically modify the hosts file again on restart.
    Avoid using an older or modified .ipsw file. Try moving the current .ipsw file (see Advanced Steps > Rename, move, or delete the iOS software file (.ipsw) below for file locations), or try restoring in a new user to ensure that iTunes downloads a new .ipsw.

  • I have an iphone 4 and do not appear the weather in central notification ios7. how can I fix this?

    I have an iphone 4 and do not appear the weather in central notification ios7. how can I fix this?

    I figured it out.  You have to have location services turned on specifically for the native weather app.  My husband already did and that's why his was working.  In the previous ios, I chose to disable location services to save battery and had the widget set to show weather for my home city regardless of where I was.  Now that doesn't appear to be an option.  Hopefully it won't drain my battery too much.

  • Pavilion dv7-1232nr dvd rw drive doesn't recognize some dvds how can I fix this problem?

    My pavilion dv7-1232nr dvd rw drive doesn't recognize some dvds how can I fix this problem? I am running Win 7 home premium 64 bit.

    If these are new original DVD, you should bring your system in for alignment. If they are copied DVDs, the drive that made them may be out of alignment and your good drive can't read the bad copy.  There is also another issue you may be talking about. Many DVD movies are assigned a country code and will not run on a machine from another country.  This was intended to prevent piracy.

  • Itunes gets to 99% then stops, does any one have any suggestions as to how I can fix this?

    When trying to download Itunes 10.5.1 the download reaches 99% then stops after a while it will say download has been interupted. I have tried using another browsers, disabling firewall and I have followed all the steps or uninstalling and reinstalling as suggested on the website. If anyone has any suggestions as to how I can fix this it would be much appriciated.
    Many thanks

    Disable your firewall and antivirus software. It can cause problems with the update process. Kaspersky is especially bad for this.

    How to burn an iMovie to DVD without losing quality?  I have iMovie 10.0.5 and iMac 10.9.4 mountain lion. I do not have iDVD. After iMovie goes through the encoding process, quality is horrible. How can I fix this problem? I have tried the apps BURN and DVD Creator for MAC. I need to finish this DVD asap and becoming more and more frustrated. Why would Apple give us iMovie and not provide us an app to burn it to a DVD and / or take away the iDVD?

    Why is there no iDVD on my new Mac? How do I get it and how do I install it?
    https://discussions.apple.com/docs/DOC-3673
    To burn a DVD with iDVD from the latest version of iMovie, you have to export the movie using the Export button and select 480p as the size. Open iDVD and start a new project, then drag that exported movie file into the iDVD menu window, avoiding any drop zones you see.
