No audio device installed after upgrading to windows 7???

after upgrading to windows 7 audio is not working error audio device not install driver error...

Hi,
You will need to identify your CPU and chipset. CPU-z is a free and safe utility that can do that for you.
If your system has an Intel chipset with disccrete or onboard graphics or an NVIDIA chipset with onboard graphics, then the drivers are here at this Realtek download page.
If your notebook is an AMD CPU and NVIDIA chipset, with a discrete graphics module installed, then the driver for your Conexant CX20549-12 will be here.
Post you results here in your thread so others rsearching for the same information can benefit from it.
Best regards,
erico

Beats audio Panel Missing after upgrading to Windows 8.1 and installing HP Reccomended Drivers

I recently upgraded to Windows 8.1 on my HP Envy H8-1450. The Beats audio Panel Disappeared and only shows IDT.
I uninstalled and re-installed the HP reccomended audio drivers several times....no luck.The sound does not sound as it did under Windows 8...actually it is crapy.
Please help.....Thanks.

lacadan,
Did you reboot your PC after installing the IDT codec in Device Manager?
I have upgraded from Win 8 to Win 8.1, have the same driver (6.10.6491.0) as you, and also have a fully functioning Beats Audio Control Panel in Control Panel.
When initially removing the incorrect Beats audio codec in Device Manager you should also check completely remove the drivers from your system, reboot, and Win 8.1 should install the correct version of Beats. You then have to reboot your PC again to complete the installation of Beats.

I have lenovo edge E531 with 8gb ram, intel core i5-3230M 2.6GHz, GeForce 740M

hi sotim01,
Thanks for posting!
1. Uninstall all components,
Open Device Manager and Uninstall your Conexant audio under Sound and ganing controllers (make sure to place a check under delete driver software for this device)
2. Open Control Panel Uninstall a program and highlight the dolby component and an Uninstall button will appear.
3. Open your C: drive and Delete any folder that says drivers if non then continue with the next step
4. Download this Driver for installation
Conexant Audio Driver
Install it and continue
5. Open Drive C: now and you should have the Drivers folder back.
Open that, Open Connexant Open Dolby Gui, then you should have Dolbyaa for Advanced audio.
Restart your PC and there you go!
Let me know your findings
Cheers!

No audio devices detected after upgrading to office 2013

Hey everybody,
I have an employee that has done an upgrade from office 2010 to 2013 and now his Lync will not detect any audio devices. The devices are detected by windows and other programs like Skype and Webex but not Lync.
Things we have tried:
1. Restarting lync and the PC itself
2. Unplugging and replugging the devices.
3. reinstalling all USB drivers
4. Made sure that the Windows audio and windows audio endpoint services were running
5. Updating software
6. turning off the power saving mode on the USB hubs
7. Reinstalling Office
This has been a real annoyance. we are thinking of switching back to 2010 if we cant fix it soon. any thoughts? Any advice would be helpful.
Thanks,
Alex

Hi,
Please try to remove the WiDi software/USB, restart Lync 2013 and then test the issue again.
Please also try to uninstall NVIDIA drivers and then reinstall them.
Here is a similar case below, and there are a lot of settings will cause this issue, you can check with it:

Driver for Officejet 4500 Wireless all-in-one will not install after upgrading to Windows 8.1

Upgraded to Windows 8.1 on Pavilion g6. Officejet 4500 Wireless all-in-one still prints but won't scan. Downloaded full feature driver. Installation quit giving error message 'file cannot be found'. Tried 'chat' sessions with no resolution
This question was solved.
View Solution.

Hello bob5e,
I am sorry to hear that you are unable to install successfully on your Windows 8.1 with your Officejet 4500 Wireless. I can see that the installation quits on you, giving you an error message. I am going to recommend trying a couple of things to hopefully make the installation successful.
1. First of all, try installing by using The Printer Install Wizard for Windows which finds the correct driver for your unit and installs it.
2. If that does not work, please try this next troubleshooting document step by step.

I hope this helps!
Good luck

HP Deskjet F2120 all in one printer driver not installing after upgrading to Windows 7

I have a HP Deskjet F2120 all in one printer. I was working fine in Windows Vista Home Premium 32 bit.
Once I upgraded to Windows 7 Home Premium 32 bit the driver is failing to install.
I have tried all the solutions provided on the HP website but none of them worked.
I also wrote a mail to HP support but they replied that its out of warranty hence they will not be able to help.
If some genius can help me I will pray for him/her that all his/her wishes come true.
Thanks you in advance.
Imroz Baig

I just got my HP Deskjet F2120 working in Windows 7. Here's how:
Insert the setup disk in your CD/DVD drive. Choose to view the files in Explorer. Scroll down to the file "Setup," which is identified as an application.
Right-click the file and select "Properties." Click the "Compatibility" tab at the top of the resulting window.
Check off "Run this program in compatability mode for:" and choose "Windows Vista" from the pop-up menu.
ALSO check "Run this program as administrator" at the bottom of the window.
Press "Apply," then "OK."
Now you can double-click the "Setup" file and run the software installer.
It will 100% work inshallah...

Vaio Care won't install after upgrade to Windows 10

Upgraded to Windows 10. When the desktop came up Vaio Care was uninstalled and then reinstalled automatically. When I opened Vaio Care I noted I had a duplicate link for the program accelerator under the premium tools so I uninstalled Vaio Care and ran a registry cleaner and then downloaded Vaio care again from the software and driver page for my Windows 7 - VPCEB11GX. When I attempted to install got a message that it was the wrong software for my operating system and noted I need to install Vaio Care for Windows 8.1 64 bit. Can you please direct me to a download link for same? Thanks.

Sound no longer works after upgrade to Windows 8.1

System:
Operating System
Windows 8.1 64-bit
CPU
Intel Core i5 3330 @ 3.00GHz
23 °C
Ivy Bridge 22nm Technology
RAM
8.00GB Dual-Channel DDR3 (11-11-11-28)
Motherboard
LENOVO MAHOBAY (SOCKET 0)

Audio
ASUS Xonar DGX Audio Device
I sucessfully upgrading to Windows 8.1 and everything was functioning after the upgrade. However, after the first time I restarted my system after the upgrade the intergrated soundcard no longer worked.
I attempted to remove and reinstall the RealTek audio driver, downloading the newest 8.1 compatible driver from the Lenovo support site.
The drive refused to installed, either via the executable or by manually installing the driver through a device manager upgrade.
So I attempted to install a stand alone soundcard, to no success.
In device manager this is displayed for both the integrated motherboard audio and the new Asus sound card:
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code
52)
If I disable the driver driver signature enforcement, neither audio option works. Instead I get this error in device manager:
"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.
(Code 39)"
Attempting to update the driver in device manager, Windows tell me I am on the most up-to-date, recommended driver, yet at the same time refuses to
allow it to function.
Extremely frustrating.
Any help would be greatly appreciated.

I have also attempted to clear out the registry Upper/Lower Filters to no success.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}
At that registry key, in the right window, is there, under "Name", either an UpperFilters orLowerFilters value?
If so, for each of the UpperFilters and/or LowerFilters value, what is listed under "Data"?
There could be an improper entry at one of these values which may be causing the problem.

Drivers missing for Envy 6 after upgrade to windows 8

There are a few missing drivers shown on the device manager after Upgrade to windows 8 for model: Envy 6-1006TX.
The four items are:-
1. PCI Device
2. PCI Simple Communications Controller
3. Unknown device
4. Unknown device
I try to find it on the support and download page on the product support but could not find.
i even go to HP Support Assistant website to try download the support assistant for window 8, but the links is not working.
Can anyone assist ? Thanks

Enter the Device Manager in Windows 8 by holding the Windows key and tapping the x key once. In the menu that is invoked, select the Device Manager. Right-click on the unknown device and then select the details tab. See the following image. I arbitrarily selected a device as an example.
Post the image by using the snipping tool. The snipping tool can be found by using the Windows key + x and selecting search. Type in "snipping" and the snipping tool link will appear for you to click on it and use as in the following image.
Post all that is before the &SUBSYS in the top PCI\VEN alphanumeric string and I can use it to see if the manufacturer of the device has posted a Windows 8 driver. Sometimes the success rate for finding a driver is greater at the manufacturer website.

No Audio Output after Upgrading to windows 7; Soundblaster Card is installed

After upgrading to Windows 7 Ultimate (64-bit), I found that my speakers (which are built into my HP w2207 monitor) are not recognized. In the notification area I have the speaker with a red x in it, and it says “No Audio Output Device is installed”.
I have a HP Pavilion D4890Y with the Sound Blaster Audigy X-FI 24-Bit Xtreme sound card. I tried looking in Device Manager, and found “Multimedia Audio Controller” under Other, which states no drivers could be found.
I tried following some of the advice online, and downloaded the latest Realtek High Definition Audio drivers, but and the download seems to run successfully, but I don’t notice any differences. When I reboot as prompted, I’ve still got the same error.
I then tried forcing the Audio Device to use a Realtek driver, but Windows protests (saying it’s not sure it’s compatable with my device, and I end up with “Realtek High Definition Audio” under “Sound, video and game controllers”, but it has a yellow exclamation point. If I click properties, the device status says “This device cannot start (Code 10).” If I try to update the driver I get the message that it cannot find the driver software.   If I uninstall the driver I’m back to the original problem (multimedia audio controller under original devices, with no known drivers).
I also tried downloading various files from the Creative site, but it’s not clear which one to use, and the 4 or 5 different ones I tried (including their recommended beta version for Windows 7), when each of them opens it says it can’t find any supported devices.
Suggestions? Thanks!
This question was solved.

Hi,
"If the driver is a previous revision install it using the TROUBLESHOOT COMPATIBILITY tool that is part of the Windows 7 OS.
To use the tool, uninstall any drivers for the sound card you show listed in Control Panel/Programs/Uninstall Programs  list.  Delete the Device from Device Manager.
Download the revision of the driver from www.creative.com  website to a folder you've created and placed on your desktop.
After the driver is downloaded, navigate to the "setup.exe" of the driver and Right Click - select Troubleshoot Compatibility  ----
Let the compatibility tool select a possible solution then use its suggestion of TRY RECOMMENDED WINDOWS SETTINGS, if it does not find a solution it will submit only CUSTOMIZE SETTINGS and let you install it as you designate."
The preceding information comes from a Microsoft Windows 7 forum regarding an issue similar to yours.
the information you provided did verify that it is a sound blaster XiFi Extreme card as checked against the Vendor / Device list.

erico

USB device keeps disconnecting/connecting after upgrading to Windows 8.1

I have a device(Pedal for Sim Racing) connected via USB, everything is working fine in Windows 7 and 8 but after upgrading my machine to Windows 8.1 the device keeps disconnecting and connecting for like every 2 seconds. But after I open the Property Sheet
in Game Controllers panel the disconnection issue was gone, if I reconnect the device the issue persist. Other people who have similar device also encounters the same issue after upgrading to windows 8.1. The issue persist with or without the device driver
installed.
Any idea, what might cause this?
Best regards
mark

I'v got this exact same problem with my Win 7 desktop. I've also got pedals and wheel but don't see it as different than all the other USB devices. I'm using a bunch of USB, but no hubs, including 3 external storage hard drives. But the momentary
disconnect appears in all devices as best as i can see..even my long time trouble free head phones..keyboard..and all. Sometimes the sound goes away and if I unplug and replug them the sound comes back, and other times I have to exit and re enter the
game. I also get video crashes ..maybe not related.IDK..and have to restart all, because I've got three black screens in Eyefinity. For years my system was trouble free and its just slowly started getting worse. I've thought it had to do with system "sleep"
etc but long ago went to never sleep max performance etc..Makes no difference. Keep thinking its my hardware or my house wiring etc..But can't seem to solve it. I replaced my Mobo/chip/ram maybe 6 months ago and that appears to have not helped. It seems
to be getting worse. I hate to start replacing parts piece by piece..cost a lot of money and sometimes doesn't help.
When I'm playing a game I can often hear "faint" sound of USB connect disconnect happening with regularity..that little bing/boink sound etc..So it must just be constantly happening...Seems weird. Didn't have anything like this happening years
ago with pretty much the same hardware and same Win7 with the continuing updates etc.
What can be causing this common problem?

No audio devices installed? (Pavilion g7-1318dx Notebook Windows 7)

Someone please help me out with this, I would be so so soooo grateful.
From out of the blue my Pavilion g7-1318dx Notebook running Windows 7 won't play any audio at all. It says that there are no audio devices installed. I've been reading other posts on this forum for a couple days now, and none of the options have worked for me. Prior to the audio disappearing I haven't updated anything or installed anything new (though yesterday, I did install a few updates hoping that maybe the problem was that something was outdated... but it wasn't). I did a system restore, and still nothing. Also, I can't record sound either (obviously) as it's telling me there are no audio devices installed.
I ran the device manager, and under sounds, video, and game controllers the only audio device listed is AMD High Definition Audio Device (which is what my notebook uses for audio apparently, when I connect to my TV which, incidentally, works fine!) but the IDT HD Audio Driver is not working at all. I've tried reinstalling the driver, but I get an error every time and it says it's unable to install it. The answer might be a simple one to someone out there, but it eludes me.
So....anyone out there who can help me? Please.

You can try few more steps..
i) Completely uninstall IDT first from control panel and then download it from here
Temporily disable the anti-virus while re-installing the IDT.
ii) Run HP Support Assitant and check if any HP updates are pending..like BIOS Update..
Recently i came across a similar issue where the sound disappered after a adobe flash update also. So you an try uninstall/reinstall flash and check also.
Let me know what happens..
Also if nothing works then the last step would be to perform a recovery (factory reset). If problem continues after recovery also the it has to be a hardware issue..
Note:
If you have HP Support Assistant installed on the computer(The Blue Question Mark) then open it ==> Complete all pending Updates & Tuneups==> Restart and Check. It may solve your problem
Although I am an HP employee, I am speaking for myself and not for HP.

"No Audio Device Installed" in Windows Vista.

Back in september 2011 I mysteriously lost my audio. I have a red X over my speaker icon in my system tray. When I put the cursor over the speaker icon I get this message "No Audio Device Installed". I went to the HP Customer web page and found the audio driver: Realtek High Definition Audio Version 6.0.1.5548 (sp37324.exe). I downloaded the program and saved it to my download folder. I put a short cut to it on my desktop. The only way I can get sound is whenever I turn on my computer I right click the desktop short cut and run as Administrator and install the program. My sound comes on. It works as long as I keep the computer on. Whenever I restart the computer I'm back to the red X over the speaker icon.
Now, Windows Update has sent me (on 3 occassions the last couple of weeks) an "optional update"...the Realtek High Definition Audio. Each time I download it and install it and do a restart,but I get the same red X over the speaker icon. It's Ground Hog Day!
My question: Is it safe to uninstall the Realtek High Definition Audio driver and reinstall the sp37324.exe without totally sending my audio into a Black Hole? BTW,I don't have a recovery disk.
I hope someone on this forum can help me. I've exhausted all avenues.
This question was solved.

Hi,
My suggetion: Totally uninstall it, reboot the machine and install it again. You can uninstall it from
   Control panel > Device Manager
   It should be under Sound ...
   Right click it & Uninstall
