All of a sudden my sound isnt working.

 I checked speakers and they  are not muted and sound at 100% How can I fix this? It's probably something silly, but I can't figure it out?

This is what I just did and my sound is back! "try a Hard Reset as follows.
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."

    Try double tapping the movie clip itself when inserted in the timeline and ensure that sound is on on the actual clip on the movie time line.

  • I took my Pavilion dv6000 apart and now the sound isnt working

    So here is the situation...
    My fan has been making noise so I wanted to clean out all the dust from inside my Pavilion dv6000. (But that isn't what i need help with right now.) So after I took it all apart and put it back together, I had this problem with turning the computer on. I think it had to do with this little ribbon cable that wasn't going in the spot where it had to be (it was connected to the power button chip.) I finally got that ribbon where it was suppose to be, and tried to turn it on. It still didnt start. The battery light would go on when it was plugged in, but nothing happened when I pushed the power button. I finally decided to give up and clean the finger prints off of it so I could bring it to my IT teacher tomorrow. While cleaning it, it all of a sudden turned on. I dont know what happened. It just turned on by itself. I mean, I could have pushed something while cleaning it, or maybe something was loose and tightened while i was cleaning it. But anyway, I finally got it to turn on. Now while doing homework, I notice the sound isnt working. I really dont want to take it apart if i dont have to becuase this is the last week of school and I need these practice tests that I put on my computer. I was wondering if there is anything I can do to possibly fix my audio without taking it apart. I was thinking if i check for the latest driver maybe that would help, but i have the latest driver and the sound still doesnt work. So does anyone know how I can fix this without taking it apart? If not does anyone know how I can fix it if i do take it apart? (for example, things to check to make sure they are connected or tightened?)
    Thanks for your time and help, I really appreciate it.

  • Since updating to iOS 6, my 4th gen iPod touch, and my 3rd gen iPad has sound in and out. Sometimes it's on, and then all of a sudden, no sound. I've tried everything from restarting to fully resetting each one starting fresh, but nothing. Please help.

    I have exactly the same problem. I have tried almost everything and I am nowhere near an Apple shop as I am working in Africa.
    Did you manage to find a solution? Help please if possible. Regards Az

    All of a sudden my iTunes stopped working, and I get the following error messages:
    1. the program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem
    and
    2. iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 126).
    Now I've checked the forums and followed the advice of uninstalling all Apple applications, rebooting, and reinstalling iTunes.
    This is not working. I've tried installing as Administrator but doesn't make any difference at all.
    There must be a way to fix this? I'm not a tech geek but I want to avoid having to take my laptop back to factory settings to sort this out.
    Thanks

    Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.

  • My phone was sitting on the table, with nothing turned on, and all of a sudden it sounds like there is air coming out of my speakers.

    My phone was sitting on the table, with nothing turned on, and all of a sudden it sounds like there is air coming out of my speakers.  It does this for 1 minute straight, then will stop. When I pick it up, then set it back down, it does it again.
    HELP!!!

    No nothing will show up on the screen.. If I push the 'home' center button it continues doing it, same with the sleep/wake button.
    I thinking it may be static out of my speakers --but I don't understand why all of a sudden it is dong this. I have had no problems with this phone, until now.

    Download/install an app is a know possible solution.
    3. Install another app from the App Store
    If all user-installed apps are not launching, it could be an Apple ID authorization issue. Download and install an app that isn't already installed on your device to reset this information.
    Note: If you have installed apps using multiple Apple ID accounts, you may need to perform this step for each account.

  • All of a sudden no sound - please help

    Hi,
    I'm running Vista Ultimate 64-bit version with a X-Fi Titanium Fatalty Pro card and all of a sudden I noticed I don't have any sound coming from my speakers anymore and when I in iTune for example press the play button to play a song the play button changes to a pause button indicating the play button has been pressed but I don't get any sound and the time counter showing where in the song I am is not moving but just stays at 0 seconds into the song. When I press the pause button it returns to a play button again. I haven't changed anything in my system when it comes to drivers etc before this happened, it happened all by itself sort of speak. The only thing I could think of that might have caused this is if some automatic Microsoft updates for Vista 64-bit got installed affecting the Creative drivers for my sound card.
    If I go into Vista's?sound settings I see my X-Fi Titanium Fatalty Pro card in there and it is reported to be?working but if I click configure and then press the Test button which normally cycles a tone between my speakers (I have a 5. speaker system) same thing happens as in iTunes ie the play button goes into a stop button indicating?it has been pressed but no sound?is coming from any speaker and then when I press the Stop button it returns to a Test button again. I have also checked in Device Manager for any problems but no exclamation marks or anything else strange in there - everything looks normal.
    I have tried re-installing the drivers?but still same problem, I have also tried removing all the Creative drivers all together running in Safe Mode in Vista and then reinstall them once again but still no go. The only way for me to get sound from my X-Fi Titanium Fatalty Pro card right now is by unstalling the Creative drivers and instead use Windows Vista's built-in drivers identifying the sound card as a 'High definition audio device' and this way the sound is working just fine with sound coming from all speakers. Of course I could stay with using Vista's default driver since this is working but it would still be nice to be able to use the real Creative drivers for my card and I by not using them I guess I'm also missing lots of other functionality I get with using the real Creative software and drivers.
    Anyone else seen this or has a clue what might be wrong?here?
    Thanks in advance for your input guys!

    Sounds similar but still not the same issue I guess because I have the problem regardless what application I'm using, I don't even get the internal Windows sounds when I have the Creative drivers installed.
    Feels strange not more people have the same problem if it's caused by a Microsoft update so maybe that's not the case after all...can't understand though what might have caused it if not that?since I haven't done anything to my computer's config lately and this problem with the sound happened from one day to the other...hmm...

  • TS1398 My ipod touch will not connect to our wifi all of a sudden. It has worked fine for 6 months and now just has stopped connecting. I have done all the trouble shooting tips available. Any other ideas?

    We bought this itouch for our daughter for Christmas (2011), It has worked fine all this time until now. All of a sudden it will not connect to our home wi fi. All the other ipods/iphones/laptops and desktop are connecting fine so I know it is not the router itself. I have tried all the standard troubleshooting tips (forgetting the network and resetting it on the ipod, turning it off an on, plugging it in and updating the software, we even restored it completely from itunes as a new ipod). It lists the network as available but then when you try to connect it just sits there with the little circle icon thing spinning, trying to connect but never does.Please help!

    So you also rebooted your router correct?  Does the iPod still connect okay to other networks?

  • Is my airport broken? My wireless has stopped all of a sudden! No solution works!

    hi, I need help please. After working fine for years my wireless connection on my desktop which is on snow leoperd 10.6.8 has stopped connecting all of a sudden. It works fine on my macbook pro and my iphone. When I turn it on I get none of your preffered networks available, I find my network and when I type in the password for my network I get connection timeout. In diagnostics I have.....
    Airport failed
    Airport settings failed
    Network setting failed
    It has connected a couple of times randomly but goes off when I try to load a page,
    I have tried loads of solutions from forums like....
    deleting networks and creating a new one
    changing channels and even tried deleting the system preference files from the library but still no joy.
    I just want to ask for any other solutions before I have to take it 50 miles to the nearest 'genius centre' to get it looked at.
    Could my airport be broken?

    Look at iOS Troubleshooting Wi-Fi networks and connections  http://support.apple.com/kb/TS1398
    Also try this - Turn Off your iPad. Then turn Off the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.

  • Zen & Win7 - all of a sudden it doesn't work anymore???

    I have the old Zen 6GB and I used it with Win7 since April 200 - never had any problems.
    Now some hours ago I wanted to transfer some files, but all of a sudden, the player is no longer recognized.
    Win7 wanted to install a driver, didn't find any and now the only thing I get is a Code 43 error.
    I rebooted Winows, I cleaned up the player, I formated it - nothing works. I tried it on another computer (XP) - there aswell it doesn't work. So I guess it's the players fault.
    What the .... is wrong suddenly and where can I find a driver for this player?

    I just tried as descripted in this link - same problem.
    Player itself seems to work, I can just check if the radio is working as I formated it several times yesterday.
    I plugged it into every single USB port I have - always the same error 43. Other USB devices (hard disc, mouse ect) work properly in the same port.
    Isn't there just any driver I can download?
