Pavilion DV6 no longer plays any audio. I am a Windows 7 user Premium 64 Bit OS...any solutions?

I am running a HP Pavilion dv6 Notebook PC with serial number: {Private Information Removed} and product number: A1U59AV#ABA.
There was a bios update automatically performed on my machine on the 30th of Oct. and since then, my audio has not worked.
Please advise.

Hi,
Try the following.
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 f10 as soon as you start the notebook 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 and then check if you now have audio.
If you still have no audio, open windows Control Panel, open Administrative Tools and open Services.  Check that the following services are all showing as Status= Started and Start-up Type= Automatic
Audio Service
Multimedia Class Scheduler
Windows Audio
Windows Audio Endpoint Builder
If you need to make a change to any of the above, just right click the service and select Properties, then in the dropdown box next to 'Start-up type',  select Automatic and click Apply to save the change.  Then click the Start button.

DP-K

    My videos on iPhoto no longer play ... the message reads OSStatus error -54.    anyone any idea what this might mean?

    Hi Terence,
    FWIW...
    I just restored my entire iPhoto library from Time Machine.  I'm running Yosemite.  After opening iPhoto for the first time after restoring the DB, it asked me to confirm my library location.  Then it proceeded to update all the thumbnails.  After this was completed, I observed what the OP reported: all photos work normally, but all videos were a.) missing thumbnails; and b.) yielding this error code when attempting to open.
    HOWEVER.  Doing a Reveal in Finder showed the videos on disk, and they were playable.  After quitting iPhoto and restarting it, it *again* said it was updating thumbnails, and now all the videos both have the thumbnails and play correctly from within iPhoto.

  • Flash Player 11.2.202.228 no longer plays my audio flv either

    Audio flvs that previously would play fine no longer play. I get "NetStream.Play.Failed". This occurs when progressively playing over HTTP, i.e. starting NetConnection.connect(null) and then NetStream.play("http://url_of_my_flv");
    Regular RTMP playback still works.
    So, I've seen two posts with similar issues in the last day or so:
    http://forums.adobe.com/message/4307125
    http://forums.adobe.com/message/4308222
    However the fix mentioned in one is not useful since I don't use FLVPlayback component.
    Any ideas?

    Hello,
    This issue was resolved using Adobe Media Encoder, see this forum post for more infromation.

    Ok, here is my ugly perl script I used to re-encode my flvs so that they work.  You need to have ffmpeg and ffprobe in your current dir, specify the directory that you want to re-encode, and create a dir 'processedaudio' where it will put the processed files, and also have an image button_blue_play.png in your local directory.  Basically, it makes a video out of the png of a few seconds longer than your audio (I found that necessary, to prevent cutting off), then adds the stream to your .flv. (it skips files that already have a video in them, and writes a list of those to 'videolist.txt')
    use File::Copy;
    $dir = $ARGV[0];
    opendir LOCALDIR, $dir;
    @dirlist = readdir LOCALDIR;
    close LOCALDIR;
    open(VIDEOSFILE,">videolist.txt");
    foreach $file (@dirlist) {
    if ($file =~ /flv/) {
    print "got file $file\n";
    $thisfile = $dir . "\\" . $file;
    $newfile =  "processedaudio\\"  . $file;
    `ffprobe $thisfile 2> test.txt`;
    open(INFILE,"test.txt");
    $havevideo = "false";
    while ($line=<INFILE>)
    if ($line =~ / Duration:/) {
    #print "line $line";
    $duration = $line;
    $duration =~ s/.*Duration: //g;
    $duration =~ s/,.*//g;
    @myarray = split(":",$duration);
    #print "minutes $myarray[1] seconds $myarray[2]\n";
    $durationseconds = $myarray[1] * 60 + $myarray[2] + 6;
    if ($line =~ / Video:/) {
    $havevideo = "true";
    close INFILE;
    print "duration $durationseconds\n";
    if ($havevideo =~ /false/) {
    unlink("tempvideo.mpeg");
    `ffmpeg -loop 1 -vframes 60 -r 29.97 -t $durationseconds -i button_blue_play.png -qscale 5 -an tempvideo.mpeg`;
    `ffmpeg -i tempvideo.mpeg -i $thisfile -sameq $newfile`;
    } else {

  • Need help getting Adobe OnLocation CS3 to work with windows 7 64 bit. Any ideas?

    Need help getting Adobe OnLocation CS3 to work with windows 7 64 bit.  The program installed ok and the S/N took.
    The program does record video and audio HDV M2T.
    The problem is video doesn't display or play back on the monitor component @ 16:9 or 720 p.  4:3....
    The scopes respond as do the audio components when recording. (with a blank monitor component).
    The video does play back on my system no problem.
    Any ideas?

  • TS3918 I am experiencing this problem on Windows 7 64 bit.  Any suggestions would be appreciated.

    I am experiencing aniTunes reinstall problem on Windows 7 64 bit.    I have uninstalled the iTunes product and reinstalled 11.02 for windows 7 64 bit but can't get iTunes going again.  The first error message I get is: "The file "iTunes Libirary.itl" cannot be read because it was created by a newer version of iTunes".  The next error message I get is:  "There is a problem sending the command to the program."  Any suggestions on what to do next would be appreciated. ( I would have posted this in Windows area had I been given a choice.)

    I believe that message can sometimes be a sign of a corrupt library file, unless of course you've tried to downgrade to an older build of iTunes. Restore it as described in this post.

  • Can't delete any of Apple's Software Windows Vista 32 bit

    Hi all,
    a while ago I tried to update iTunes because it could no longer recognize my iPhone.
    Everytime I tried too, my computer crashed within a minute. Now I tried to delete iTunes and the same thing happens. Then I tried to delete any of the other Apple software like Safari, Quicktime etc and the same thing happens. Whenever I try to remove or instal any other software I have no problem at all.
    I currently have 10.7.0.21 installed concerning iTunes.
    Does anyone know how to solve this problem because it is driving me crazy and it is hurting my business.
    Greetings John

    Apple directly does not respond, but there is a new team here " apple specialists" they Suppose to respond to questions un answered for more then 24/48 hours. Unfortunately it may look to them as you have answered your own question, so you may be out of luck on that. Me personally in situation like yours use that utility to uninstall.

  • Macbook Pro MA609 (ati x1600) + Windows-7 64 bit. Any chances?

    Hello,
    trying to install W7 - 64 on MBP with Mobility Radeon x1600 video and have "standart VGA display". 3.1 update didn't help.
    Did I miss something or I won't have it running anyway?

    I'm looking into running Windows 7 64bit on the exact same MBP you have, so I'm curious as to whether or not you've found a solution yet outside of the forums.
    Do you think it might be that the bootcamp 3.1 update is only for Windows 7 32bit and not for the 64bit version?

     2. Operating System installed (if applicable) 
       Windows 7 64-bit
     3. Error message (if any) 
         Fingerprint scanner shuts down. After an hour or so, the fingerprint scanner shuts down. I've owned this laptop for about 3 months and it has only started recently. Could someone tell me how to keep the fingerprint scanner always on?

    I have the same problem with mine. I called HP support and they made my update bios along with updating the finger print scanner drivers. This seemed to work for a week then it started shutting down again so my problem is still unsolved aswell.

  • Hp Pavilion dv6-6c35dx Windows 7 beats audio problems

    Product name : Hp Pavilion dv6-6c35dx
    Operating System : Windows 7 Home Premium Service Pack 1 64 Bit
    I'm having a problem with some of the sliders in my beats audio options. The sliders in the graphic equalizer section work just fine, but the ones to the left of it - bass, treble, center, etc - have no effect on the sound no matter how I adjust them. Below is a picture of what I'm talking about.  This problem seemed to happen shortly after I needed to reset my pc back to factory settings. I've gone to the drivers section of the hp website and got the HD IDT audio driver for my model called "sp58131" and installed it but all it did was reset the sliders, the problem still persists. Is there anything else I can do?

    Hi Vivi,
    I understand you are having issues with your HP Pavilion dv6-6c35dx Notebook and Beats Audio. I would uninstall the driver from the device manager and any others that might be in the Audio. Then reinstall it from here.
    Hope this helps.
    Thanks.

  • Can no longer play audio files embedded in a PDF

    I can no longer play embedded audio files in PDFs in version 11 for Windows XP (though I could on an older version). The audio will not play on my Mac either. How do I fix this?

    I should add that these are mpgs of a television series. They were made with QuickTime Pro 7.6.2 or .3 just before the new iTunes and Snow Leopard came out. I can open them with either QT X or QTPro7 on the Mini and they play fine. I don't know where to point the finger since they play through iTunes fine on the PPC Leopard Mac and not the Intel Snow Leopard Mac. It could be how the new tunes works with the OS but those kind of hooks are harder to find than they were back in the old OS7,8,9 days. I'm not meaning to be an old bloke longing for the old days cause i love the magic of technology.
