His default intermittently T430

The sound is a fail intermittently on my T430.

Close and open the lid for access and return after hibernation sometimes restore sound. When it does not restart the machine usually restores sound. But the sound does not again after an indeterminate period.

Opening of Ubuntu Linux in Virtualbox now displays the message "some devices audio (PCM_in, PCM - mic) could not be opened."

I would appreciate any advice.

As this problem appeared out of the blue, I suspect an update of Windows.

Loss of windows 8 "audio" Googling update highlights a recent update
KB2962407. Uninstall this update solves the problem.

Of course, I now wait to see what other problems this unistallation
causes :-)

  • My his default keeps beeping while I'm on my lap top

    My his default beep warning while I have on my lap top How to find why he do this?

    The noise occurs even if you are not using the computer, or only when you use it?  It happens all the time or can you assicate with any activity you perform?  The frequency with which the sound does happen?  It occurs during playback of a song or other audio file or do that make it go away?

    Right-click on the Volume icon in the notification area of the taskbar and click sounds.  Browse the list of sound events (if necessary), and then click Test for each of them to see if you can identify it as the sound that you hear - then we can have some clues as to why it is being implemented.  It could also be quite, but if it's a common event then this process may discover.

    Try a boot minimum http://support.microsoft.com/kb/929135.  If the problem goes away then it's just a matter of tracking down the culprit at the origin of the problem.   Follow the procedures described in the article.  Once found, remove, delete, disable or uninstall.  Once remember to put Vista in normal status, as described in the procedures. If the problem occurs in clean mode then just restore the system to normal and reboot - this solution will not work.

    Start in safe mode and see if the problem is here.  A result allows us to narrow down the search for the cause.

    I hope this helps.  Let us know if you find it (or if you do not have) and what happened in clean and safe mode.

    Good luck!

    You can try to remove all the current drivers first and then installing those latest. I suggest that also consult you the site Web of Conexant for latest drivers, as is the real manufacturer of the sound chip.

    If this does not help, you can also try to disable all audio enhancements, see:

    Hello Brian

    This path is not easy to say why this happen and why your laptop is blocked. From time to time to check regularly stop and don t stand-by option use for an extended period of time.

    We don t know what additional software do you use and what is running in the background.
    If you have noticed this problem a few days ago, try to roll back BONE several days back just to see if the problem persists.

  • How to get my computer default to Microsoft using Windows 8.

    Hello! I am trying to set my default settings of the computer to Microsoft, I can use my Microsoft email and send a video webcam. I went into the control panel and went in select default and changed computer for Microsoft and press OK.  But then he said he wet his default values in windows media player and when I went in my webcam to send my email it says that it has not been implemented for email. So, why it does this? It takes a few minutes to Setup? Any input would be greatly appreciated!

    You may or may not know that Windows Vista was the latest OS to come with a desktop e-mail program.  Windows 7 and 8 do not come with any successor to the Windows Vista Mail program.  Instead, you can get it as a download in the Windows Essentials page option.  Of course, Windows 8 has a rudimentary basic e-mail application, but it is designed for the Tablet/phones and the lamp.  If you want something that compares to the program post Vista (for example the possibility to send e-mails from office based programs such as your webcams), you'll want to get the free download of the essential elements in this link before you move forward.  Then it will work fine.

  • Tecra 8000/windows98se register

    I have a tecra 8000 which has a default intermittent starting
    When his absentees for awhile. Next time you start it has errors on the windows registry and stop to repair the registry, once it starts successfully, it is ok, including reboots, unless you leave for a few hours or overnight. Someone has an idea of what could be the cause

    Hello

    It is not easy to say but is obviously an entry in the registry is damaged and may not be readable or understandable to the OS. After that it must be written again. On this path, it is not possible to give you an answer why this happens. It is possible that some application that runs on your unit to this entry.

    Sorry but I can't give you more information about this

  • Mail problem in trying to reply to a message in El Capitan

    Hello!

    Since the upgrade to El Capitan, my mail is sometimes a bit unstable. His latest problem is that when I click on reply to an email, an empty message appears and cannot then be closed by clicking on the red button. I have to close Mail and reopen it. I can then close this message, but I find myself with a message in the drafts folder, which should also be deleted. I try to answer again and sometimes the message opens correctly and other times, I get another empty message and must go through the same procedure. If she continues on several occasions, I restart the computer and it works normally. This is a default intermittent and very annoying. I ran the first aid in disk utility and my OS and Mail seem to be the latest versions, so I don't know what could be the cause, or how I could solve it. Does anyone have any ideas of what I could do to fix this please?

    Thank you

  • Hijacked home page. Tried to reinstall the browser

    My pc has been infected. Adware and others. Some extensions have been added to the browser. I uninstalled them. I have also quarantined just guilty possible. I tried the suggestions on the Q & an area. There is no add-on which could be the cause. I deleted all. I also uninstalled firefox.
    I have re-installed and it's the same thing.
    Whenever I opened the browser before uninstall, a new open tab which showed an error page. I have attached a picture.
    Now, when I open the browser, he did what it took to do: display windows and tabs from last time. But when I open a new tab, the problem is still there. It is not load the default home page, but the error page in the image as an attachment.
    I really expected everything should be back to normal after you have uninstalled the bloody browser.
    I ran a boot time scan with my anti-virus just-downloaded and analysis online.

    Edit: the browser keeps closing on its own. very annoying. I'd appreciate any help.

    Hello

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • Click the menu button

      click Help

      then select restart with disabled modules.

    If Firefox does not work, you can start Firefox in Mode safe as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.
