Speakers have stopped working after the flash BIOS updated for Windows 8

I had recently changed the OS of my HP Pavilion dm4t-2000 for Windows 8. After that an update of the BIOS flash me suggested by HP Support Assistant, speakers have stopped working. I tried to reinstall the Audio Codec, but it does not work. Could someone help me please?

jaikvk,

Go into Device Manager and uninstall the sound and restart the computer. This will reinstall the driver once more.

Also, it could be a bad installation of the BIOS; You can go to HP.com and re download the update of the BIOS.

Let me know if it helps.

    Open the Device Manager and check if no yellow exclamation point appears. If you can see this yellow sigh perhaps the sound card driver is not installed correctly.

    In addition, please plug the headphones to your laptop and check if you can hear anything through the headphones.

    the stoppage of work - has indicated that there is no connection to the Internet, the PrintToGoLog.txt had much more detail).

    Other users of similar problem after a reported BB playbook KB2992611 updates has been applied,

    Thanks for the info, this will help others with the same question.

    That KB was for all windows systems, but was mainly for Win Vista business.

    You can reset IE in Internet properties, program tab, or download another or do a system restore to November 10.

    Firefox is not affected because it is not incorporated in the system as IE.

  • My device audio stop working after the installation of update security for Windows 7 for x 64-based systems (KB2286198)

    Hi, since Windows Update automatically installed this patch my audio device stop working. It does not appear in Device Manager. I've restored the system to a previous point and works now. I have disabled the automatic updates of Windows, but I really appreciate if Microsoft Support could check this because at some point, I will need to continue the update of Windows (because of several security mistakes!).

    Thank you!

    I restore my system to an earlier point and did not work! After several hours of searching for a solution in the web I realized that (fortunately!) I had a copy of the registration precedent and do a comparison, I noticed that some missing case book lines:

    In

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HDAUDIO\FUNC_02 & VEN_14F1 & DEV_5051 & SUBSYS_103C30D6 & REV_1000\4 & 38993660 & 0 & 0002\

    The 'Control' key with a string value 'ActiveService "=' Modem' was absent.

    Also in

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HDAUDIO\FUNC_01 & VEN_14F1 & DEV_5051 & SUBSYS_103C30D6 & REV_1000\4 & 38993660 & 0 & 0001

    I added a 'Control' button with a string value "ActiveService" is"ksthunk".

    Finally, I restart my system and Windows again recognizes my camera and the driver installed!

    Of course this solution depends on the machine you have. I have a HP Pavilion dv2000 with Conexant High Definition SmartAudio 221.

    I hope this helps someone!

  • DNS stopped working after the latest Vista updates

    Yesterday my Vista Home Premium has been updated by Microsoft through the automatic update process. After the update and reboot network stopped working. I was able to trace this DNS no longer works. I was unable to solve the problem until I supported updates, after which the system returns to normal operation.

    Now, of course, updates want to be reinstalled, but I don't want the network to fail again. Any ideas?

    Change how to get updates:

    http://www.bleepingcomputer.com/tutorials/tutorial140.html

    Understand the Extras in Windows Vista and Windows Update info is at the link above.

    Right click on those you don't need > UAC prompt > it hide.

    Never install party hardware driver updates 3rd through Windows updates.

    Go to the manufacturer's website, instead.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Download updates but let me choose whether to install them - if you select this option, Vista will download the updates on your computer, but not install them automatically. If you want to install updates, then you must install them manually. You should only select this option if you have a reason to not install updates automatically. Only advanced users should use this option.

    Check for updates but let me choose whether to download and install them - if you select this option, you'll be alerted when there are new updates available for download and install. You can then choose to download and install the updates that you want. This option should really be reserved for people who know exactly which updates they need, or those who have little access to the Internet.

    See you soon.

    Firefox extension: 'TrueSuite 5.2.500.16' stopped working after the last update of firefox (30.0), although subject: said plugin activated.

    I tried to reset firefox and search for similar problems, unfortunately found nothing.

    It is also weird empty space before the address in the address bar

    other extensions and addons seems to work very well.

    Firefox 30 spent some less commonly used "Always turned on" plugins "asking to activate. To check and change this to TrueSuite, you can use the page modules. Either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click on Plugins. Then on the right, check the setting on the right side of TrueSuite.

    Any difference?

  • When and what can expect to happen to my computer after the end of support for windows XP?

    What is Pageheap?

    The answer to your direct question, when you think that say you, is a Google search away.

    -It is not supported to Microsoft for an operating system you probably have to worry.

    It is your own ability to stay static, I want a computer faster, better equipment, a new printer, scanner, camera, etc.

    The manufacturer of the software or hardware that you use every day will probably abandon Windows XP well before the April 2014 date when Microsoft stops by releasing the same critical patches for Windows XP.

    Their new printers will have only Windows Vista drivers, maybe just Windows 7.

    Their new scanners, cameras, etc. will be the same.

    I don't see the major software companies (AutoDesk, Apple, Adobe, etc.) continues to produce products that would work on Windows XP, Windows Vista and Windows 7 and what comes next in 2014.

    Everyone always loves to find a single entity to blame for their reluctance to change with technology - but usually it's just the changing world overall - not a single instance of it.

    Having said that - there are many people who still use Windows 98 twelve down on the line.

    They can't see certain things on certain web pages, cannot use certain devices, they might be able to pick up at their local drug/warehouse, even store and using the latest versions of major software packages are probably a lost - cause but they do very well in their microcosm.

    So - it mainly depends on you and your ability to do not change.

  • HP ENVY laptop - 15-ae178ca: Second monitor stopped working after the automatic update of HP

    I use my laptop with a second monitor (HP Pavillion 22xw) connected by HDMI. It was working fine until yesterday (including yesterday it worked), when a message from automatic upgrade HP was shown to informing him that the system needs to be restarted. After that, my second monitor stopped working. The system will not identify it more. I tried another cable, I rebooted several times, I tried to update the specific Intel graphics driver, I tried to uninstall and install manually another (I can't get this one done, because when I run manually downloaded driver there is a message saying that I need to contact the manufacturer). Please notify that I need my second monitor is fully functional!

    Thank you for visiting the Forums from the HP Support! The forums are a great place where you can find solutions for your problems, with the help of the community!

    I understand that you have a problem with the display and wanted to help you!  I see only after an update, the external monitor no longer works.

    Given that this problem happened recently, have you tried to perform a System Restore, to define the notebook to its previous working state?  If this does not work, have you tried to update the drivers of graphics Chipset and BIOS on the HP website directly?  You can find the drivers for you product here: drivers - HP's ENVY for laptop - 15-ae178ca

    Please post back with the results.  Let me know if this information helps you solve the problem by marking this message as 'accept as Solution', this will help others easily find the information they seek.  In addition, by clicking on the Thumbs up below is a great way to say thank you!
