No Sound HP Pavilion dv9925nr Notebook PC

About two days ago, I lost all sound to my laptop.  I am getting the following messages at startup:  Could not find Conexant audio device, application cannot run properly and No audio output device installed.  I have not made any changes.  This seemed to have began after a MIcrosoft update.  I have downloaded the Conexant driver from the HP website to no avail.  There was a point where I did have sound but it didn't last very long.  One other observation,  I am missing the Sound, video and game controller link in Device Manager.  I'm at my wits end and need assistance in diagnosing/correcting this problem.  Is this an indication of a hardware error?

i had the same issue. my laptop is not detecting the hardware so i cant update or anything. ive tried restoring to a previous date, a few days before the problem started, but it did nothing. i had installed some updates for the audio and the graphics card and the internet modem and for the BIOS from the hp website. the audio came back for a few mins twice and one time it tried on its own to install an update for the high definition bus but it want able to do it and the audio died again. I've tried all of the suppourt sites and hp site but they have no hellp for it. i think im gonna have to take it somewhere to get fixed

  • No Sound from Pavilion 15 Notebook PC

    HP Pavilion 15 Notebook PC updated  to Windows 8.1 as recomended by the installed HP Support assistant
    There is now no sound from the internal speakers but when connecting external speakers to the output jack they give sound.
    I've followed various sets of instructions to update drivers / roll back driver all have failed.
    The drivers installed are currently Realtek High Definition Audio Version 6.0.1.7071
    Any body got any ideas?

    Hello peakay, welcome to the HP Forums.
    It appears that you have no sound from the internal speakers on your notebook, that external ones work fine. I will try to help you with this.
    I would recommend trying the steps in this document: No Sound from Speakers (Windows 8).
    If you need further assistance after this, pleas provide the model and product numbers for your notebook.
    Thank you for posting on the HP Forums.
    I worked on behalf of HP.

  • Speakers disjointed and lagged sound - HP Pavilion dm4 Notebook PC

    Every now and then my laptop faults when playing videos/music. The laptop is a HP Pavilion dm4 Notebook PC with Intel Core i3-2330M @2.20GHz
    Basically sometimes when playing a video/music the speaker is distorted and laggy. Usually when watching a video this is also laggy. The computer seems to run really slowly and trying to move the mouse or type it takes a few seconds for the letters to appear.

    I would think that with 6GB of RAM you wouldn't be having lagging issues either...
    Especially since it is under warranty, let HP look at it and see what they say.

  • Sound quick launch button doesn't work when i installed windows 8 in my hp pavilion dv3z notebook

    When installing the audio driver, was it installed by following the prompts or in compatibility mode as outlined here?
    Based on the Software and Drivers page for this unit, the unit was not tested and certified for Windows 8.  This means that some functionality may not be the same since the unit was not designed for Windows 8.  See this site for information and to find out if it has been tested for Windows 8.
    If the sound driver has not been installed in compatibility mode, then I recommend using the Windows 7 64bit driver found here and using the linked steps above to install it in compatibility mode. 
    Let me know what happens.

  • No sound after installing windows 7 on HP Pavilion dv1710us Notebook PC

    I recently helped my uncle install windows 7 on his HP Pavilion dv1710us Notebook PC
    and there was no sound after installation.. i downloaded several drivers for the realtek high definition audio driver (R2.39, 38, 37, etc)
    then i tried the original driver from the HP drivers page and installed it.
    usually when there is no sound, there would be a red X on the volume icon, but when i installed the original driver from the HP drivers page, there was no more red X.. Thinking that the sound was fixed, I tried to go on youtube and watch a video... i see the green bar moving up and down on the volume slide, but then i can't hear anything.
    So is there any realtek high definition audio driver compatible for windows 7 on the HP pavilion dv1710us?
    Is there something I have to do, like right click on the application and then change compatibility settings?
    thanks in advance.

    I got it to work with windows 7 32 bit. I just went to hp website to support and downloads section. Type in your model number, then select windows xp as the operating system. Then download the audio driver and save it to your desktop. After the file is on your desktop you need to right click on it and click properties, then go to compatability tab and tell it to install as windows xp service pack 3. Hit apply then install. Hope it works for ya, worked for me.

  • Lost all sound on my HP Pavilion dv6 notebook

    I have a HP Pavillion dv6 notebook with a Widows 7 operating system and have lost all sound. Any suggestions as this is a 6 month old notebook?

    I had the same issue last night after an automatic BIOS update.  I read about 7 pages of posts that seem to deal with the same issue and found a combination of actions that seem to have restored my audio functions completely.  I posted the solution and it resolved the issue for at least one other user who commented back.  It it works for you, please also post that it worked for you.  I suspect there are alot of users out there that have or will be experiencing the same issue.  It would be nice if HP would post the appropriate solution, it seems to have been going on for awhile.
    1. Through 'Device Manager / Sound, video and game controller' I uninstalled my audio driver (IDT High Definition CODEC) and also deleted the driver software for the device.
    2. Through 'Programs and Features' I uninstalled the IDT Audio Software (vers 1.0.6418.0) that was installed with the BIOS update.
    --> This forced a reboot.
    --> When my system rebooted it automatically searched and found the appropriate audio driver -- now I've got audio and Media Center works fine...
    Hope this helps you.

  • Sound Playback Issue with IDT High Definition Audio Codec HP Pavilion dv6 Notebook PC

    Since i bought this laptop, every time i use skype or the Windows Sound Recorder, i hear static that drastically increases in volume. Uninstalling the IDT High Definition Audio Codec prompts my computer to automatically install the driver again, this usually fixes the problem, but after restarting my laptop, the problem returns.
    Does anyone know a permanent fix to this issue?

  • Laptop no sound HP Pavilion g6t-1d00 CTO Notebook PC Windows 7 64bit

    laptop no sound HP Pavilion g6t-1d00 CTO Notebook PC Windows 7 64bit everything enabled. I don't want to try to install wrong code from forum searches.

    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/sp55001-55500/sp5503​6.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 and plug in the AC Adapter.
    Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 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 - it will automatically load an audio driver, but just let this complete.  Then 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.

  • Product name: HP Pavilion 15 Notebook PC Issue- No sound

    Product name: HP Pavilion 15 Notebook PC
    Product number: F9T46EA#ABU
    Hi ,
    I have no sound on my computer, beside the speaker symbol in the toolbar is a red 'x'. When I press this it says detecting problems and then it says- 'Problem - one or more audio services isn't running' and then 'not fixed' beside that.
    I investigated to see which audio service it was that wasn't functioning and it turns out that Windows Audio Service  is failing to run.
    How do I resolve this problem?
    Áine

    Hi,
    Open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers.  Right click the IDT device and select Properties.  Click the Driver tab and then click 'Update driver'.  Select 'Browse my computer for driver software' and then select 'Let me pick from a list of device drivers on my computer'.  Left click 'High Definition Audio Device' once to highlight it and then click the Next button to install it.
    Has this made any difference?
