No audio after windows update

this goes for the hp a1320n as well as the a1324n and probably for more. these models have a realtek high definition (hd) audio device with front panel inputs/outputs.
i had an issue where i lost sound after some windows updates. there seems to be multiple scenarios that i believe are all related. ultimately what would happen was that i would attempt to get sound out of the speaker, either by playing a song, or just trying to configure windows sounds, or the realtek sound manager test program and no sound would eminate. it looked like it was playing the sound, but nothing audible.
i tried the usual uninstall/reinstall of drivers - same. i tried reloading various operating systems as well. i could get it working, then after some windows updates, i would lose it again. of course, hp "tech support" was no more help than a 6 year old who has been shown a picture of a computer.
what i realized today was that when i had something plugged in both the front and the back, i got sound! wtf. anyway, i read some posts that suggested disabling the "auto-jack detection" - same. i uninstalled the driver, shut down, removed the white aux cable and green input/output cable from the motherboard, rebooted, let windows detect the driver - still no sound. however, when i shut down, reinstalled the cables then booted windows without messing around with the driver again, alas i had sound! f'ing windows and hp. i've been working on this for about a month now. hope this helps for anyone else who's experiencing similar issues.

If WU breaks your audio again, it is probably a new Realtek driver that is installing from there. I would turn off driver updating in WU. You can also use Device Manager to rollback the driver which works most of the time.Uninstalling it and rebooting only installs the newer one again.

Dell Latitude E6520 fails to boot after Windows Updates

Hello,
I have a Dell Latitude E6520 that is not starting up after Windows updates. It installs updates and requests a reboot, after which it blue screens at the splash logo and reboots again. This goes on indefinitely. The only way to repair it is to boot from
a recovery disk and run:
dism /image:D:\ /cleanup-image /revertpendingactions
This is after running dism /image:D:\ /get-packages and noticing that several updates are still in an "Install_Pending" state. These are the kb's that are pending:
kb2982378
kb2978742
kb2977629
kb2976897
kb2973112
kb2972211
There were other updates, but those showed as installed. I would post the WindowsUpdate.Log, but I do not see a button to attach a file and the log is very long. Here is what I think is relevant towards the end of the log:

SP 2010 - Getting "An unexpected error has occurred. " message when accessing Sharepoint site after windows update - Windows 7 Home Premium

Hi,
I am new to SP 2010. I have installed Share point 2010 server (trial version) on my Windows 7 Home Premium Laptop by following the below link.
http://msdn.microsoft.com/en-us/library/ee554869%28office.14%29.aspx
Everything went fine and was able to see the new sharepoint site after completing configuration wizard. SP2010 Central Admin also worked fine.
However, after windows update, sharepoint site is not working. I was able to see the site working for more than a day before windows update. SP2010 Central Admin is still working. Executed "PSCONFIG" after
update but still no good.
I saw a warning "The Security Token Service is not available" in Central Admin and did some research to fix the issue but nothing worked.

Windows Update Error 800B0109 after Windows Update Agent 7.6.7600.320 Installed

Hi, I have this error message when running windows update, it happened after Windows Update Agent 7.6.7600.320 installed.
Any idea how to resolve this?
Thank you.

Hi，
Please make sure that your antivirus application does not scan the files in the
%windir% \SoftwareDistribution directory on any computer on which Windows Update Agent is installed.
You can also temporarily turn off the antivirus application and check the result.
Or run the following commands, and press Enter after each command:
Net stop wuauserv
cd %systemroot%
Ren SoftwareDistribution SoftwareDistribution.old
Net start wuauserv
Try to install updates again.

Profiles being reset after windows updates?

Hi All
I'm having issues with Outlook 2013 SP1 resetting our users profiles after Windows Updates have been applied. Their profiles are being reset whilst their previous profiles are being renamed to "BACKUP of <profile name>".
Office 2013 x86 has been deployed via VL Media onto Win7 x64 machines and we are distributing the ImportPRF registry key via GPO (set to Update) in order to customise the profiles on first run. (basic email account and attaching a default PST file)
It appears that after windows updates are applied outlook is triggering the first run process again and therefore resetting the users profiles back to the standard set in our PRF.
We used this method to configure Outlook 2010 and for the years of deploying Office 2010 we never had any issues. Can anyone suggest what might be going on here or what might have changed in Office 2013?
Thanks

I do not see much about coloum 14, but I am guessing this file is stored somewhere and its corrupt. Update.xul suggests that it is the update file. Do you still have this in your downloads folder? There are two places for update and for a clean reinstall:
[http://www.mozilla.org/en-US/firefox/new/] in a private window will give you a new install or you can choose from here: [https://www.mozilla.org/en-US/firefox/all/]
This is what the file should look like; [http://hg.mozilla.org/mozilla-central/log/7a2edc5171e6/toolkit/mozapps/extensions/content/update.xul] If you can copy and paste that file from a working browser we can see the issue, but it will just look the same as the error.
if you can replace the contents of the file locally with what it should look like it will fix the error, but who knows if there are other errors. May be best to delete the updater and save all the profile folder contents.

I want to backup my pinned tabs and my bookmarks as they have been lost several times after windows updates

several times after system crashes and sometimes after windows updates my pinned tabs have disappeared. How can I back up the pinned tabs and bookmarks??

Firefox stores the bookmarks and the browsing history in the places.sqlite database file..
There are 10 rotating daily JSON backups (bookmarks-####-##-##.json) in the bookmarkbackups folder within the Firefox profile folder, one for each day that Firefox is started.
*http://kb.mozillazine.org/Backing_up_and_restoring_bookmarks_-_Firefox
Pinned (App) tabs and tab groups are stored in the sessionstore.js file.

Though I wish to be ready for Windows 10 installation, I need to have operable PC for my work.(This is Win7 sp1, home eddition) It would be great if anyone could assist me on this. Thank you, Piko.

I have this problem. It happens without any warning.

No sound from laptop speakers after Windows update installed Realtek HD Audio

Laptop is HP6626US with Windows Vista 32 bit SP2.
I had an error with Windows Update which was recently fixed. When I ran the update Realtek HD Audio was installed, among many other items. I now have the red circle white X by my speaker icon and do not get any sound out of internal speakers.
The Driver version is 6.0.1.6662
Direct X version 11.0
Audio Codec ALC 268
In Device Manager Under Sound, video and game controllers Realtek HD Audio is listed with Unimodem Half Duplex Audio Device if that is helpful.
Help Appreciated.

Hello,PaulM25.
I see that you're having an issue with the sound on your notebook. Typically this means the Drivers don't exist and can also be considered as a hardware issue.
I have a couple of questions for you before we get going.
This is your notebook (HP Pavilion dv6626us Entertainment) correct?
Did this issue occur after you updated the audio drivers?
Now, you can go ahead and try these steps to resolve the issue.
Please completely remove the drivers for the Audio Device in Device Manager and “Control Panel – Programs and Features”.
Reboot the computer.
Please check if the device will be installed automatically after the computer starts. If not, please go to Device Manager and then navigate to the Audio Device, right click on it and choose “Update Driver software”
If the issue persists, please try to manually install the device driver which comes with the computer to see if it works. (You can also go to HP website to install the drivers. If you cannot find it, please give me the detail information of the device or the computer, such as brand, model, etc., I will help you search for the proper driver.)

I have an HP Pavilion G7. Four days ago Windows pushed out an update and audio worked afterward. Next day (three days ago), HP had an "important" update that kept popping up so my wife downloaded that update and installed. Since then, no audio from the PC or working on my external speaker.
I did a system restore rolling back one week - no change.
I reinstalled the HP audio driver - no change.
No audio now, totally DOA. BTW, the slider bars do show audio being processed but not heard.
I'm guessing the Windows update or the HP update (whatever they were) directly caused this.
Any help appreciated.

I would check the Windows updates and HP updates.
You can see when tMicrosoft Windows updates were installed by accessing Programs and Features and then selecting view installed features. Uninstall them one at a time.
You can check on the HP updates by accessing the log that is in the HP Support Assistant to see what was installed.
Best regards,
erico

Bad sound in my x-fi audio after windows upd

I have accidentally downloaded this @ windows update on tuesday?
Creative - Sound - Creative X-Fi Audio Processor (WDM)Creative Sound sofware update released in June, 2007?
After that all my sound options were gone and i have a terrible bad sound.
Is there anyone who can help me to solve is this problem?
I am running win xp

If you need to remove entries from the registry it's not as bad as some people make it to be. You do have to be very careful because it can disable your system. First go to the Device Manager and uninstall your sound card. Go to Start Menu and click on RUN, enter "regedit" and hit OK. Click on the + tabs by My Computer then HKEY_LOCAL_MACHINE.
Make?a backup copy?by going to the FILE tab at the top and select the Export option. Name the file HKEY_LOCAL_MACHINE and save?it to your desktop. You can use this file to restore your registry to?it's original state?if needed.
Now click SYSTEM and then CurrentControlSet then click on and highlight Services. Go back to the top?and under the Edit tab select Find. Enter "Creative" in the box and then click on the Find Next tab. This will find any reference to the word Creative. Any time you find a reference delete the folder that the reference exists in. Go back up to the Edit tab after each time you delete a folder and click the Find Next tab and it will search for the next reference. Do this until you find all references in the Services folder. This should remove all the drivers for your Creative sound card but will also remove any drivers for ALL Creative products on your computer. If you only have the sound card this won't be a problem. Close the Registry Editor and restart you computer. You should be able to reinstall your card with the original CD or the driver of your choice. If you don't use the CD you'll have to tell Windows where to find the drivers. Restart your system a couple of times to make sure all your services load and it runs as it should. When your satisfied that all is Ok you can delete the file you saved to your desktop. ?Just be very careful what you delete and you will be OK. If this doesn't work you may have to format the hard dri've and start from scratch. Good luck.

Plz help, "device not detected" after windows updates?? I have so

I have An Audigy 2 ZS, and have the latest drivers. It has been working PERFECT, LAST NIGHT I had like 0 WINDOWS UPDATES, i dont' know if any of these had anything to do with this. But, I just now went to the icon in the task bar, and went to change SPEAKER SETTINGS to switch to HEADPHONES as I ALWAYS DO, I was surprised when the "unable to change the sound device to your selected device", you press ok, and it comes up TWO MORE TIMES, Right after each other.
I DO HAVE SOUND, FOR NOW. I have read other mentioning this error, but I didn't seem to find any answers. I can't go to speaker settings, or Surround Mixer,
OK, NOW I tried to go to GRAPHICS EQ, and an error came up that said "THE AUDIO DEVICE SUPPORTED BY THIS APPLICATION IS NOT DETECTED, THE APPLICATION WILL EXIT"
What is going on?
I went to device manager and it says that the device is working properly, and I DO have sound.
I DON'T get it. And I'm not likeing this. This is starting to worry me.
Does ANYONE know what is going on.. PLZ?

Thanx for the reply. I just now fixed it. I'm not totally sure what I did. Earlier I had uninstalled the device from Device manager, and then restarted, and it installed the drivers from the CD. It didn't fix it. So, I ran the LIVE update here at creative.com and downloaded the version I had before, I guess because when i had ran the update before I uninstalled the device the update wasn't there.
But, it started to update, and said something it had to restart the pc in order to install the update, and after it installed the new "creative audio console" it now works.
the whole thing was strange since I dind't lose sound at all. Just couldn't access settings.

No sound working after windows update

My notebook restarted itself to make updates, once i logged on i found that the sound is not working on music files, web pages etc. other than the windows sound. The other thing i noticed is that the mute button will not go off or on? i tried to troubleshoot but nothing..
I found that left clicking my sound icon and cliking on playback devices and then left clicking speakers and headphones and clicking 'Test' led to a pop up;
"Device in Use
The device is being used by another application. Please close any devices that are playing audio to this device and try again."
I have checked everywhere but i can't find the device being used anywhere?
I'm not willing to lose by Beats Audio. Help?!..
