No sound: no audio output device is installed. no choice of audio device in Device Manager.

I started my pc windows 7 today like any other day, and he has not played the music to start. Then I looked at the volume icon in the corner and there was a big red X on the speaker symbol. I go over it and it displays the message "no audio output device is installed". I was confused, so I went to check the Device Manager and there is no sound Devices(or whatever it is called) tab. I then restarted my computer 3 times and still have no sound. I would try a system restore, but I can't choose restore points after the first start I did this morning. My sound card is a card for the Asus M2N - SLI. Any Suggestions?

Hi j03d03190,

  • Do you see unknown devices in Device Manager?

Step 1

It seems that the Audio drivers are deleted or removed from the computer. I tried to check for audio drivers for your card mother M2N SLI and could not find drivers Audio in Windows 7. However, I suggest to download the Audio from Vista drivers from the Asus site and install it and check if that helps you solve the sound problem. Access the link below and download the Audio drivers for Windows Vista and install it.

http://support.ASUS.com/download/download.aspx

Step 2

You can also run Windows update on your computer and check updates and install and check it it helps you to install the audio drivers and to solve the sound problem. Access the link below and follow the steps to install Windows updates.

  • No Audio output device is installed and no "Sounds" not listed in Device Manager.

    I turned on the computer yesterday and immediately noticed the Red "x" of white/circle on the "speaker" icon. Roll the cursor over the icon gives me the message "no Audio output device installed. I have already read through the forums and tried some of the suggestions offered without result. Here's a quick deterioration of the situation. I am running Windows Vista Edition Home Premium service pack 2 on a Dell Dimension DM061 (32 bit). No updates have been downloaded and the system was not put into hibernation. I tried restoring the system without result. The Device Manager shows not yet "Sound, video and game controllers" to watch the drivers or disable them. He has not disabled or disconnected devices to display. To the best of my knowledge the soundcard is part of the motherboard with this system, so I've no idea what driver I could find. Any suggestions would be greatly appreciated. Thank you

    Hello

    I was hoping that the main issue was in the BIOS but it is also why I posted links to Dell
    Support and their forums because he may be known issues with your model.

    Check this click - Device Manager - anywhere in the area in white/white - and then VIEW - chech to see the
    Hidden - devices you can locate the audio device it?

    -----------------------------------------------------------------

    If necessary:

    Try an InPlace upgrade or repair Installation to see if your audio device can be reset.
    If so it would probably be a good idea to update or re - install the latest drivers.

    You can use another DVD that aren't copy protected but you you need to own
    Product key. It must be the same version 32 or 64 BIT Vista OEM. Also the system
    machine to usually sell the cheap disk since you already own Windows. Don't forget to make a good
    backup or 3 (security in redundancy).

    ==============================

    If those don't help you probably need a real computer store (leeks and pics
    at a Best Buy or other department stores) or Support of Dell.

    ---------------

    Another possibility if there is a problem with the hardware with the audio device:

    Car sound can be turned off in the BIOS and card USB sound a speedboat can be used
    that is not expensive.

    Use your favorite search engine search - sound card USB or USB its adapter.

    I hope this helps.

  • Satellite L300D-243 - no audio output device is installed

    Hello

    I look for a similar problem in the forum but have not found anything that's been resolved.
    I'll try to explain how my problem came.

    My sound is fine until when a few days ago I tried to lower the volume and then all of a sudden it froze.
    Came a message that his unit has stopped working.
    I restarted the laptop, but it has not started at all, nothing on the screen, just the fan runs at slow speed. I figured it by removing one of the plates of ram and then with the possible one began almost success except he was not an indication of a sound, just the message "no audio output device is installed", and an 'x' on the taskbar icon sound.

    In Device Manager it is not anything related to an audio device High Definition Audio Controller except under the menu system devices.

    So what do you think, is this a hardware or no problem and is it fixable.
    Hope someone can give me an answer.

    Thanks in advance!

    Have you read this thread:
    https://Forum.Toshiba.EU/showthread.php?82746

    Open the Device Manager.
    Then expand the sound, video and game controllers, click on the Realtek High definition Audio choose: turn OFF, then turn ON.

    If you can not find Realtek HD audio device (this is the sound card), so I recommend you click on view and choose 'show hidden devices '. Perhaps the sound card appears in the list...

    In addition, visit the Realtek driver page and download and install the latest Realtek HD audio driver.

    Hope that it could solve the problem

  • No Audio output device is installed, no sound in Device Mangager Toshiba Satellite Vista

    I have the dreaded red X on the Volume control, "no Audio output device is installed", no. Sound Devices in device Mangager / Toshiba Satellite L355D-S7901 running Vista-32. FixIt seem to fixit, or find.

    The solutions that I have seen and tried on the Web just walk me through the first steps of the three solution and then drop out of cyberspace. I heard sound on this machine before, briefly, and then she returned to the non-cooperative State. I saw a few techno-jibberish once on the drivers are properly installed, to ensure that they are saved and enter into the registry and remove, from repair, screw up as much as you can before throwing the PC to the wall because you don't know what they speak and are to afraid to taste the risky proceedures, restore cannot help , or something.

    What happened, what is the solution of 4th or 5th person has told and Toshiba wants hundreds of dollars to diagnose, and then just says that the computer must be replaced if they are too lazy or too ignorant to investigate and solve problems or reveal the real solutions. Reinstall the correct drivers does not work, there is no folder Sound and the game in Device Manager controller. I'm tenatious.

    I also have a USB Port that Windows doesn't recognize after him malfuncitoned, why? FixIt can't find it, can't fixit. I suspect someone stuck the wrong connector on the USB port and fried something - can't rip out and replace it? I came back home, limited, vision limited, duration of limited attention, limited by the reckless lack of "Technicians" to help. I guess you are supposed to be able to pay and pay and pay for computer assistance, or die with your computer.

    I just want this computer works correctly, as long as it costs, so I can go on the problem in my life.

    Torchured!

    And there are the Toshiba Forums you can ask

    Or you can backup your data and reinstall the operating system

    You don't say if you have a Vista DVD that accompanies it.

    Otherwise, you have a recovery Partition to reinstall Vista from

    Under sound, click on manage audio devices

    Under playback (tab)

    Choose speakers you have in your output device

The Device Manager there is not even a sound, video, game controller section. Sometimes when I put into hibernation and back on I have sound and everything works fine (except when I run itunes and it stops again), but I say that I have no audio device again to restart the laptop. I have the vista updates this. All ideas

    Thank you

    I had the same problem with my Compaq F700 series laptop. His was a work day and does not not the other. I couldn't use most of the patches because they need to have the tab of sound, video, game available and also lacked this tab.

    I tried to do system restore and rolling it back, but the problem has not been resolved. What finally worked was restoring the system to a MUCH earlier date, as one month before the problem. When finished restoring the sound was still not fixed. HOWEVER, the computer OS (WINDOWS 7) necessary to re - install a bunch of updates and after the updates have been installed, everything worked. I suspect that the original problem was a bad update (I.e. has not installed correctly) and one to ride the system goes back to a time before the bad update and then re-installing the update was the fix.
    That said, if the restore option does not or cannot be I would try searching through the Add/Remove programs in the control panel to uninstall the updates of the system, and then restart the computer and let updated them, re - install.
    Good luck
  • I have no sound on my computer and a message stating: "no audio output device is installed" what shout I do to solve this problem?

    I asked the same question yesterday and your answer have no sense to ask whether the sound is embedded or on a sound card. I don't know because I'm not a technitian. This problem has happened twice before you don't have not helped me and then either and I ended up paying $750.00 for each visit to repair. This is the third time it's happened and I don't have a $750.00 to fix the problem. So what's left for me to do repair the damage?

    Always include your version of Windows.

    Right-click computer or my computer, devending on which version of Windows you have.  Select 'manage '.  When the window opens (you may need to tell UAC to allow him to), select "Device Manager" in the left pane.  Expand "audio, video and game controllers".  Do you think your sound device it?  If you see, there a yellow triangle with an exclamation mark inside?  If this is not the case, what do you see in this section?
