No Audio device

I use a desktop Pavilion a1587c with XP Media Editon computer.

I just installed a NVIDIA GeForce 640 video card to replace the origional dead card.

It seems that audio HDMI card caused my card onboard Realtek HD audio stop.  I have no sound, the speaker in the taskbar icon has disappeared, and the page of sounds and Audio devices says no Audio device.  In Device Manager, under sound video and game controllers it appears as unknown.  The Device Manager also shows that no driver is installed.

I disabled the audio part of the NVIDIA card and tried to restore my audio card, without success.

Restoration of the pilot indicates that he has re-installed the driver, but it still does not work and no driver show in Device Manager.

I downloaded the drivers from the HP site, but trying to install gives me a BSOD and instant reboot.


Go into the BIOS and enable the audio embedded.

  • NCAA games go to bad audio device, even when I say o/s otherwise. How to replace Firefox?

    I guess that's a FF issue, since everything else seems to work OK. I have a USB headset plugged into the USB hub under my desk. I use the properties of the Audio devices > Audio in the control panel (XP Pro) to switch between the headphones and speakers of the laptop.

    The problem is that I can't sound through Laptop speakers playing games via Firefox NCAA without unplugging the USB headset physically. I hate to crawl under my desk to do it. If I tell the OS what speakers to use, do not change it. I should be able to force audio to speakers for computer without physically disconnect them. I use my laptop to a large number of web conversations with my helmet, but I don't want to physically disconnect when I what to listen without headphones.

    No sooner had I posted my complaint that I discovered that other applications have the same problem, although I said otherwise. And FF works fine if the USB headset is activated as the device by default until I start FF (or tab maybe the FF). Maybe the 'problem' is the operating system, if it does not notify a change of aircraft FF. Or, maybe the problem is FF, if it does not acknowledge the notification from the OS.

    In any case, I now have a work-around that seems compatible with other applications on Windows. However, any other ideas would be appreciated always. I think that changing the operating system's audio playback device must notify immediately and performed by all applications using the headphones/speakers/whatever, regardless of when the application started.

  • Motherboard integrated audio device missing randomly after turning on the computer.


    Old location:

    I recently changed my laptop Elitebook 2540p motherboard. When I installed windows 7 Enterprise 64-bit on my computer the computer lists not all audio devices in the Device Manager page. I checked the bios for all faulty settings and they are all good. Theres no yellow mark in the list of devices is and all the drivers appear to be installed.

    New location:

    Installed windows 7 and computer again found / installed normally audio devices. I tested computer for hours to read the audio data from it and everything worked well. I restarted computer several times / re installed the battery on the computer. A reboot the computers audio button mute fast under the screen seems to be orange and the speaker sound in windows icon has been marked as X I have check the list of devices in Device Manager and there is no audio device listed (no sound device at all). Once I restarted computer and before the computer started downloading windows I pressed the mute button and it turned blue. Then I went to windows and audio devices / audio devices has been registered and work / sound working again.

    Old location:

    I have motherboard integrated IDT audio device.

    When I try to install audio drivers from hp for 2540p site I get "your system does not have the minimum requirements for this patch." And the Device Manager does not list all IDT audio devices.

  • No audio device on the laptop

    Thank you.

  • Portege R700 - Win7 - cannot find the driver for USB Multimedia Audio Device

    Are there any Windows 7 drivers for the "USB Multimedia Audio Device" found on a R700 with the Toshiba Hi Speed Port Replicator II (PA3916U-1PRP)?

    In "Devices and printers", there is a device in the section called a + USB Multimedia Audio Device + Unspecified +. Windows 7 can not find the drivers for it. Audio seems to be working through the port replicator.

    The only related issue I've seen is that sometimes, when I press the "eject" button, Windows complains that a device is in use and the ejection is defective. This is very similar to that reported as ' [Undock R700 question P3838 |]»].

    In my case Windows tell me an application to use it or the device in use. I strongly suspect the audio device.

    I have not found a solution so eject manually despite the failure or sleep it and then eject manually. I didn't notice the two approaches being necessarily better.

    HI PeterH,

    Just a simple question: do you use the preinstalled version of Windows 7 at Toshiba and you have most unknown devices in Device Manager or just this USB Multimedia Audio device?

  • No audio device installed Satellite L300-28R (PSLB8E-12T018GR)


    My English isn't the best, unfortunately. Maybe someone can help me.

    The following problem:

    A Satellite L300 ran without problems until now with windows 7 (32 bit). I had then increased PC speakers of this came of trust with a USB flash drive that will serve as an audio interface for mailboxes. He has been infected by the first recognized by Win7, installed, and I could use Ihne. But then the sound card integrated (Realtek HD Audio) is disabled. Now, when I remove the USB audio interface I have no more sound. There is a lack of complete the "Realtek HD Audio" entry in the audio control.

    In the Device Manager is not an entry ' Audio, video and game controllers' also appear longer. The interesting thing about the HD audio driver, but he is always installed correctly. It is found but no entry for more video, audio, game controllers, and if I was in the toolbar the look of speakers just click on it a red cross when he get up "no audio output device installed."

    On this, I tried to uninstall the system USB audio drivers (no problem) has restarted. Not always the same sound problem.

    That's why I completely uninstalled all drivers audio and tried Windows 7 default drivers. The same problem. I uninstalled the audio drivers, this time I tried the drivers Toshiba, same problem.

    Fact is I can remove all the drivers, reinstall, which happens without problem and the error message, then it is same because "drivers have been installed, the machine can be used now" I click on what there is also my drine Realtek HD Audio. But then I opened the Soundsteurung he wrote me, "No audio device installed" it's almost as if the onboard sound has been disabled in the BIOS, but unfortunately there is no entry exists, since the BIOS is usually something to bend parameters.

    I have integrated sound card in my vemutung the BIOS from a USB audio interface is disabled, I would now like to 'hidden' bios unlock options and manually activate the sound again. Unfortunately, I do not know how do I unlock the BIOS.

    Is there anything else maybe ideas, suggestions or solutions? Have already the system is set up with new same problem, the drivers are installed, the device is detected and marked as ready, but not input in the audio control and no entry in the Manager of devices for "audio, video and game controllers".

    Once had a similar problem with my desktop where I could pass without any problem, but the onboard sound in the BIOS again, unfortunately, what with the Toshiba BIOS Lite is not the case.

    Hope someone can help me here, slowly I won't now, so that a new installation was not, I see the problem with the BIOS setting.

    Answers in German would be nice

    Greetings and thanks

    Hi mate

    To be honest I'm not quite sure what the problem might be m.
    Your ad is also a bit confusing.

    First of all, the BIOS is not similar to the BIOS that you can find on desktop PC and as far as I know there is no special option to enable or disable the sound card.

    So I think that in your case, it s BIOS not deliver.
    I think that its Windows operating system that makes some disorders who knows maybe the registry is confused up similar facts is that you should see some yellow exclamation points in device if Manager driver would be absent or you should see an unknown device in the devices list

    The latest Realtek audio driver could be downloaded directly from the Realtek page, but even if the Realtek audio driver is not installed Win7 standard driver should recognize the sound chip and sound must be detected during the operating system installation.

    I think you should try to install a driver from Realtek but if this won't help you, then you should try a new installation of the OS. Get it back you would help define the laptop back to factory settings and I think it's the fastest solution in your case

    My product number is G6R97UA #ABA.

    OK, it's exactly what I thought it was in the first place... the Intel HD Audio chip.

    Try to manually install the driver that I posted as follows.  If you have not deleted the file I posted, go to Device Manager and click on the audio device HD requiring the driver.

    Click the driver tab.  Click on set to update driver.

    Select her browse my computer for driver software option and navigate to the folder of the driver that was created when you ran the file.

    This file will be located in C:\SWSetup\sp72370.

    If you have deleted the file, download and run again the driver, close the error window and follow the procedure above.

    I see the hardware ID you posted as supported in the driver file, so it should work.
