No audio device installed HP z600

I have a HP z600. Currently, I don't have speakers installed. However when I plug my headphones I hear no audio. That or not I have also have plugged headphones I get the red x by the speaker icon in the status bar.

My system is HP Z600, NVidia Quadro 2000, Windows 7, 20 GB of ram, no speakers with the exception of the headphone is plugged in Device Manager, I have 4 instances of the HD Audio, NVidia drivers. I tried to uninstall and reinstall. drivers. I tried to update the drivers. Ive tried to install the driver from realtek. Nothing has worked. Any help is appreciated.

Just a thought, but I know that you can disable the audio embedded in certain types of BIOS (I dunno if that's all). I ran into that here at work %

I hope this helps.

  • 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

  • Re: Satellite U300 - no audio device installed

    Rercently I lost audio and one audit result is back there is no audio devices installed.

    Remove the audio driver, clean the registry and restart. Download a [pilot |] if it does not it, there may be OS or hardware related issue. Then, you should to restore factory settings. If t still exists, there is a malfunction of the sound card

  • No sound - get the error no active mixer device or no audio device installed

    Original title: downloads for devices sound cards/audio/active mixers
    Hello, I got my laptop crash currently and when I came back, I have no sound except for the beeps. I can't hear CDs or audio files on different Web sites. I can livestream and see a video, but not hear. I plugged headphones and have the same results. I get the error codes are no active mixer device and there may be no audio device installed. I have a windows xp operating system. I don't know where to go to start a download for sound cards.
    Thank you.


    We can try to install the drivers manually. It seems that every time that your device has crashed, someone reloaded Windows without having to install the device drivers.

    Let's start by trying to install the audio driver first. This one we might have to do it manually, but the others should be automatic. This gives a test:
    1. go to: and download the 7zip archive manager
    2 download, register, and install the utility on your computer
    3. once the utility installed, go ahead and re - download the audio driver package
    4. save the package on your desktop (or somewhere easy to access)
    5. once the package downloaded, find him, do a right click and choose "extract here...". "or something similar in nature. Basically we will extract the contents of the package and install it manually
    6. once the content is extracted, click START
    7. in the menu START, right-click on "Computer" and choose "Properties".
    8. in the upper left corner, click on Device Manager.
    9. find your Multimedia Audio Controller, right click and select 'Update Driver'... »
    10. click on "Browse my computer for driver software".
    11. click on the button 'Browse' at the top
    12. place where are the files extracted from this driver package
    13. Browse in the folder extracted and select the listed file. If there are several of those who choose an and and if it's just, the Setup will continue. If this is not the case, the installation program displays and error and then you just go back and try the alternate
    14. from there, the installer should walk you on the rest of the steps to manually install the driver package
    As far as your other drivers go, I would recommend going to the bridge site and looking for a driver of Modem for your computer model. The audio driver should be supported at this stage, and the Ethernet driver can be a joint wireless adapter you have. You may need to find a driver for it on the site of the gateway, OR if you bought the adapter you need to go to the device manufacturer's Web site and get you a driver there.
    Let us know what happens

    No audio device installed! Help, please! No sound! I've tried EVERYTHING!
    If the new version of Itunes is out, version 10, and I decided to upgrade. After the upgrade, however, I have lost all sound. The low speaker has that a x I googled this problem for hours and all possible solutions do not work for me. When I go into my device manager, I don't have even a tab that says 'his', which does not help. I have no driver installed, so there is no way to uninstall it and then reinstall the driver. I also tried my services and then go to Windows Audio properties to make sure that the startup type is automatic and is listed like that.  Honestly, I feel like I've tried everything! I tried a lot of things but there are so many, I do not remember all. I tried something via the Recovery Manager and that no longer works. No matter how many times I reboot my computer, this problem is still evident. Someone help me please! If it is useful to know, my laptop is a HP Pavilion dv6000.

  • There is no audio device installed in Windows 7

    Recently, after that my father could not turn on the protector of windows he was afraid he had a virus on our computer. It turns out that it was simply because we are under windows 7. MSE runs under windows seven. It does not recognize the name of the driver removed from the computer and audio. After that I realized why the Defender turned we tried reinstalling the audio driver with mixed success. There is no sound on our computer and the program appears in the Manager for devices with a warning triangle. When I open the program the master volume down without any apparent way to raise it. By clicking on the button mute or dragging the roller on the meter is not do. The audio store is no help and the computer repeatedly says there is no audio devices installed by clicking on the when I try to adjust the system volume or manage audio devices via the control panel. We have a Dell E6540 and our CODEC IDT audio driver.

    Original title: Audio problems

    I found a solution to the problem. The compiter was pluged into a hub. After performing a clean boot, I uninstalled all audio ports via the hub. After doing this, I was able to install the driver. Windows Defender has not executed because MSE is the security system by default on windows 7.

  • Satellite A300 - no Audio device installed


    During the last week, I had trouble with my audio.
    The first incident occurred then that I was browsing the internet, and suddenly an error pops up and off my sound. When I checked for audio devices it says there where not installed and when I checked the Device Manager there is also none installed. I then uninstalled the driver/software from my computer and reinstalled them, but yet the drivers were not recognized. Instead, it there was only a HDMI output driver that would say that he plays sound, but none would come out of my speakers.

    Then I had abandoned all hope and played a video (no sound) when all of a sudden sound began to play off the speakers and all the audio drivers have been recognized.

    Then happened the same incident as the first, and now still can't solve this problem.

    Also mistakes keep coming by saying "Soundchanger.exe" does not work.
    Any help would be great! I uninstalled and reinstalled all the correct drivers and always use system restore, but the sound still doesn't work.


    Has this happened with Windows Vista preinstalled Toshiba?
    If yes then I would recommend restoring the operating system using the Toshiba HDD image or the recovery disc.
    I think that it is necessary if the pilot of its installation or update didn't help.

    The new installation of the OS would also be useful to check if this is a hardware or a software only problem.
    Usually after the new installation of the OS, the sound should work fine. But if you this sound issue still appear then a hardware problem could be the reason for that, as mentioned by Akuma.

    I had some problems of sound, but only after the installation of XP_ _Win. Some MS patches that are part of the SP3 has been installed no. and therefore the sound n t function.
    So I deleted the audio driver, installed SP3 and after reboot the new, I installed SP3 and the sound worked again
