Sound devices missing post-10.6 install

Did an upgrade on my MacBook Air. Everything else went smoothly... except suddenly my sound devices are missing. No output, no input. No more software updates to install.
Anyone have any idea?

As per a forum search here will show you if you're looking hard enough, the flex cable and sound board go south on these things due to frequent overheating. This was confirmed by a Genius yesterday. They're going to replace the cable and sound board, as well as order a new logic board and replace that if they find other heat damage.
As to your problem, I saw some suggestions that the sensor that detects optical/analog output for your jack may have become dirty and to try and "clean" it by repeatedly inserting/removing your headphones. I don't know if that'll help you at all, but I do remember seeing it.
Good luck!

Satellite U400-17R - Sound device is not working after installing XP

Hi there,
I purchased a U400-17R Model with Vista Home. i Formatted it and installed Windows XP Professional downloading the XP drivers from Toshiba site.
Everything works but my Sound Device is not working. when i check in the Device Manager the Sound Drivers are there and it says working properly.
I am Lost...Can anyone please help?

Hi!
On Windows XP you have to install two patches from the Microsoft Knowledge Base for high definition audio cards. If you only have SP1 or SP2 you need the patches but if you have SP3 you dont need it because they are a part of SP3.
Both patches or SP3 must be installed *first* and then the sound driver. So if you have installed the sound driver first you must remove it and then install the patches again. After this it should work with the sound:

New 945GCM5, unable to install sound device

Hi all, please help,
I used the parts on the list below for a friends PC whose old motherboard was fried by power fault, some parts used, some new.
Anyway, I installed all the parts into his case along with the old hard drive. Formatted and installed Windows XP and then started to install the drivers from the CD for the Intel chipset, Intel onboard VGA drivers, Realtek NIC and Realtek HD Audio driver.
All the drivers installed and recognised the devices except the sound drivers. No matter what I do I can't get windows to install the drivers, it just won't recognise the drivers as belonging to the device.
The device shows up in Device Manager as PCI Device with the yellow exclamation mark to show a problem, when I disable the onboard sound in BIOS it disappears so it is definitely the sound device (onboard Realtek ALC888 chip, I believe).
What I have tried so far,
1. Tried install from CD.
2. Downloaded latest drivers from MSI, and tried install.
3. Downloaded latest drivers from Realtek, and tried install.
4. Tried to update driver from driver tab of device in Device Manager with the above drivers.
5. Formatted and reinstalled XP over again, and tried 1 to 4 again.
Is there a problem with the motherboard? Am I wasting my time?
Is there a way to force the install of the drivers?
Sorry if I've gone on a bit too long! Any help would be much appreciated, I've spent ages trying to fix it!

Your problem may have to do with SP3. There are known problems with SP3 and KB88111 / Universal Audio Architecture (UAA) High Definition Audio class driver.
Try this:

If that doesn't work, try again with SP2 only.

Toshiba Portege M500 sound device not Installed

Dear All, I Have a trouble with my toshiba protege M500. After i am turning back to the factory install then the sound did'nt work. I try to install hardware detection software buat all off them said that the 'Sound Hardware not Installed'. What i have to do to solve this problem ? Any body have a tutorial or suggestion for this matter ? I want to see the board but i didn't know how to dissambling this Portege M500. Regards, Tpk99

Hi,
Try to install everest software. You can find it at download.com . Once downloading it will give you a report of what kind of sound device you have and a link to download the latest driver( probably it will be from toshiba web site).

*SOLVED* Device not detected/ No driver installed for X-FI Fatal

OK!!!! the only reason I signed up here was to post that I have (for me) solved my problem.
Before I get into details this occurred on a fresh system with latest drivers for hardware used.
The problem was installing my X-Fi card on my 680i m/b (striker extreme).. when I would install the driver it would simply crash the computer and when it started up the hardware was not detected to used the software and the device manager said no driver installed.. I tried everything.. I installed the driver in safe mode (yay it worked without crashing) then I booted for windows only to have it blue screen for a second and restart... repeating the cycle.. so i reinstalled windows again... I tried installing the driver different ways in windows.. nothing worked... I gave up...
BUT!!!
today while i was at work I decided I would try one last thing.
this is what got it going. I have SLI 8800ultras that covered the PCI slot on the bottom of my board and I though I would try the card in this slot to see if it worked there... so I disabled SLI took out my bottom card put in the sound card in the bottom slot, installed the driver... It installed 00% no crash... even better it worked after the restart!!!... so then I had to test if it worked in the top slot so I powered down, moved it up to my top PCI slot and windows auto set the driver for it (as it was already installed) It worked in the top slot now... Finally I put in the second 8800 to make sure it worked with this slot in use... It still worked fine with SLI enabled. because I was unhappy with the mess I made installing drivers all the time as I did with the many crashes I decided to do a fresh install of windows making this card work from the start so here is what you need to do if you have a 680i board with SLI. this is exactly what i did with my fresh install.
install only one GPU card..
Put the X-FI in a different slot that isn't giving you problems
Install windows
Install service pack 2
install your chipset drivers
install sound card drivers
power down, change sound card to permanent slot
test - power down
put in the second GPU card
install GPU drivers
Good luck you all having this problem.. I hope my solution helps you.

I think I?got a similar?problem earlier today when I was messing around with?onboard audio?that I later removed and after unplugging a?USB headset.
Have you checked the device manager, is there any higlighted hardware that has a exclamation mark next to it.
I fixed the issue by simply uninstalling the WDM device with the exclamation mark and restarted.

K9VGM-V no sound device in WinXP

Got my new machine all running and installed but can't get the sound device to show in Device Manager. On logon, PNP trys to install the device but only lists it as a "PCI? device". When I try to manually install the driver, the RealTek Audio drivers and codecs do show up as installed, but they're not associating with the mysterious PCI device. I've flashed the BIOS with the latest version and installed all the newest drivers for the chipset, etc., but still can't get the device to show up. I'm thinking I've messed up some switching thing on the motherboard, but I can't figure out what. The sound card isn't listed anywhere in the BIOS so it must be hardware???
I appreciate your help.

Hey, thanks, BK. The patch was the ticket! I didn't need KB888111xpsp2 because it was included in SP3, but KB835221 was the missing piece. As soon as I got that installed and the machine rebooted, the new RealTek HD Audio drivers loaded right up. Works like a charm, now! Thanks loads!

You have troubles installing onboard audio right?
Have you installed Realtek drivers from here? --> http://global.msi.com.tw/index.php?func=downloaddetail&type=driver&maincat_no=1&prod_no=260
If no change install those patches: https://forum-en.msi.com/index.php?topic=113078.msg846427#msg846427
then retry with realtek drivers installation

Boot-camp Win XP SP3 Sound Device drivers incompatible

Hi,
I have recently installed windows XP on boot camp and installed all the correct software, but the sound card does not work! I installed the boot camp software on XP from the Leopard DVD and everything worked fine except the sound. I then installed the recent update for boot-camp 2.1 from "Apple Software update" hoping that this would solve the problem. It didn't. I then went back to the Leopard DVD and explored through the installers in there. I knew that the Sigmatel driver was missing, so I ran the installer for that from the CD. The installation seemed to work, and it asked me to restart, so I did, when windows came back up again the installer popped up to complete the installation but half way through, an error message came up and told me that "The driver you are trying to install is incompatible with this version of windows. Click OK to end the setup". I then tried going into Device manager and manually installing the drivers from the Sigmatel directory. yet another message stopped me "This file does not contain information about the device you are trying to install" and clicking ok takes you back to driver selection. I then thought about trying the installer for Realtek and went through the same process, this time the installer finished correctly but the driver was still not present, so back to device manager again. In the Realtek folder there were at least a dozen files containing drivers, so i tried them all, without success and seeing the "does not contain information about the device" message.
If anyone knows how to help, plz do. Thanks

Hi..yeah..can anyone help on this please..
im also experiencing the same problem..ive also tried realtek R249..
thanks...

Elitebook 2540p Motherboard changed. Integrated motherboard IDT audio device missing in windows 7.

Hi,
Old situation:
(I recently changed motherboard for my computer Elitebook 2540p. When i installed windows 7 to my computer the computer doesn't list any audio devices in device manager page. I've checked bios for any faulty settings and they are all set right. Theres no yellow marks in device list either and all drivers seems to be installed.)
New situation:
Installed windows 7 again and computer found / installed audio devices normally. I tested computer for hours to play audio from it and everything worked fine. I restarted computer several times / re installed battery to the computer. On one restart the computers audio quick mute button below the screen appeared to be orange and the sound speaker icon in windows was marked as X. I check device list again from device manager and there was no audio devices listed (No sound devices at all). After that i restarted computer and before the computer started downloadin windows i pressed the mute button and it turned blue. I then went to windows and sound devices / sound was working again.
Old situation:
I have motherboard integrated IDT audio device.
When i try to install audio drivers from hp site for 2540p i get "Your system does not meet the minimum requirements for this update." And the device manager doesnt list any IDT audio devices.
I then installed xp and the computer found IDT audio device normally and the sounds are working correct.
New situation:
After i did new windows 7 install and all my audio drivers installed / devices showed in device list / audio worked i downloaded audio drivers from HP driver site and installed them to the computer.
Audio problems has not been occured again after my HP screen mute button turned to orange / Windows sound speaker was marked as X / Computer didn´t find any audio devices.
Currently waiting if the problem occurs again and trying to think what would cause this ( Hardware problem or software)? And how to fix it permanently.
Any help for this problem?
BIOS is updated to newest version from HP driver download center.
All windows drivers are installed.

No Sound device recognized

I have a e9290f Pavilion. I just re-installed the system with HP recovery disks. I have no sound and the device manager does not see a sound device. It has onboard sound. I downloaded the new driver from the HP site and installed, re-booted and it still does not see the device. My thoughts is the onboard sound on the motherboard is "messed up". I bought this computer in 09 and it hasn't been used much. It is running Win 7. I went to the bios and changed the setting from Auto to Enabled and rebooted, that didn't work. I went back to Auto and rebooted, that didn't work. I'm afraid I need a new motherboard or have to buy a sound card. Any thoughts would be welcome.

Hi
Thanks for your reply. I did several steps and made a determination it was the Realtek sound chip on the motherboard. As in my previous post I did a clean install, that should have put the original drivers to be loaded, didn't work. Then I downloaded the updated drivers, didn't work. Then I went to the Reaktek site and downloaded their drivers for the chipset on my motherboard, that didn't work. Then I did a google search and found that this motherboard has had several problems and indeed HP last year was replacing them. Because this computer at that time was being used by my son, I didn't know of the sound problems. He went to work in Florida about 6 months ago and the computer was sitting in the closet until about 1 month ago when I took it down considering to put Win 8 on it, and discovered the items I have been posting here. The solution was/is not to replace the motherboard ( I hope nothing else goes wrong with it because from what I read on the google search, sound going out is/was not the only problem ) but to install a sound card. So I went to Best Buy and bought a Creative sound card and installed it, drivers etc. and now everything is working fine. Thank you for trying to help. I checked out your link and that help page does absolutely nothing for you if you have no sound device showing up in device manager. That clearly means device manager is not seeing a sound device, all the drivers in the world and all the troubleshooting is not going to change that. Thank you for trying to help.

Using Raid and enabling use of second sound devic.K8N/SLI 7100 mobo.I'm lost

My specs are in my signature, question is should I configure my hd's in Raid, will I get a performance increase? and what is the actual process in doing so? I have a floppy that came with my mobo titled raid configurator something, Keep in mind these hd's are Ultra ATA/100 with 8mb cache and not sata or scsi, and I have two sound devices, the onbard sb live and a pci sb ls.....can i use ls for my mic?....how should I do it? I heard someone mention doi9ng the same thing before i just can't find the post....thank you

RAID is worht the speed. Just configure it in the BIOS and instal Win like on a regular drive. XP SP2 needs a 4K cluster size to instal IIRC.

Go to device manager, then expand "System Devices", and locate "MS UAA bus" Right click over it, then click "Disable".
Reboot and enter in "Safe Mode", {hit "F8" just after bios post screen}
Once done go to device manager then expand "System Devices", and locate "MS UAA bus" Right click over it, then click "Un-install".
Reboot PC, then run Realtek driver installation again.
If problem persist use:
>>> Unknown Devices 1.4.20 Beta with updated ID lists <<<
Thanks Svet
Still no solution ....
But I don't see any "MS UAA bus" under the System devices
What will be the effet of the "UKD_14-20_Beta_updated_july_08.exe " that you provided link to ?

My sound system does not work AFTER installing pc to tv wireless connection

my sound system does not work after installing hp pc to tv wireles device when I am using lap top for other purposes.

Hi,
You don’t install VS2010 on the client PC, then where did the Form Invoice not work? When you run it from another version of VS? Or when you run the application with application.exe?
Based on your description, one form works well, another form does not. I assume that two forms are in two different projects, then please check the .Net Framework used by the two projects. If they are different, you can use the
one used by the Form contact for Form Invoice.
Because this issue is a project issue, I recommend you to consult it on some application forum such as Windows Forms General forum for better support.
VS General Question forum mainly discusses
the usage of Visual Studio IDE such as
WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help
System and Visual Studio Editor.

Lost sound devices now blue screen of death when updating creative drivers.

I have an XPS with windows 7, dont k now what the sound card is, I have factory installed software for Creative X something extreme, and Realtex.
Now I had been trying to get sound via an optical cable to an AV amp with no success. I had tried disabling and re enabling sound devices, then I tried updating the drivers, realtex was ok but the Creative drivers caused the blue screen of death with the message IRQL Not less or equal"
I tried all options in device manager including rollback, every time I try anything I get that blue screen of death, whats more, in "Sounds" in the control panel, I have lost two of my sound device options that do not appear even with "show hidden devices" so I now have no sound.

Hi Nambo,
Device manager should list the exact hardware in your desktop. But normally, integrated audio jacks will appear on the same backplane as other motherboard components, while an add-on card will have its jacks in an expansion slot. So you should know whether you have integrated or add-on.

There must be a real solution to "Windows found driver software for your device but encountered an error installing"

"Windows found driver software for your device but encountered an error installing"
I've spent hours researching this error - Seems like many people have the same issue although there is no difinitive fix or known cause.
I'm hoping someone here has an answer.
Windows 7 Home Premium x64 OEM (HP)
This is not an upgraded Vista system.
It's not a specific driver related issue as it's the same response/effect be it graphics/chip set/usb/printer drivers.
Please dont suggest to flatten and re-install or run a repair install - It's not an option, I only have remote access to the unit
as it's currently in field use.
This is a machine specific issue - identical machine purchased at the same time and configured the same has no issue.
So the story.
User has been fine for weeks - no hardware of software changes except Windows Updates.
A Camera/USB connection that was working no longer does.
Tried in all USB ports
Plug in - windows announces found new hardware, tries to install drivers then fails
with "Windows found software for your device but encountered an error installing ...."
Device manager finds and identifies device although it is in the 'Unknown Device" category.
Manually updating drivers via search/internet or point directly at a driver has exactly the same effect.
Thinking this was just the camera drivers - I researched and downloaded new drivers from camera manufacturers sites
Fuji and Canon.
Same effect.
Deleted/uninstalled drivers completely, deleted/uninstalled all USB root hub and USB devices (hidden and visible)
SFC /Scannow finds no error
Cold boot finds USB and chipset(?) devices on boot attempts to reinstall then we get
"Windows found driver software for your device but encountered an error installing"
So now I have no usb devices at all - memory stick/card reader/printer...... nada.
in fact if I try to update any device driver I get the same message generated.
Restore point does not help either.
After much trawling I found reference to a permisions issue and stale driver cache data.
(This is using an administrator account - not user with admin permissions?)
I'm willing to try anything at this time
I deleted the infcache.1 and other .dat files under c:\windows\system32\driverstore
Copied the usb .inf and .pnf from the appropriate FileRepository directory into c:\windows\inf
Uninstalled all the usb/unkown devices from device manager again.
Rebooted
Takes a little longer to boot as I take it it's rebuilding the driver cache then
a very short hurrah!!!
I can now use usb memory card and pen drives - no issue
Plug in a camera or printer...
"Windows found driver software for your device but encountered an error installing"
Several attempt at this trying different driver versions.
It should not be vendor specific, the other field machine that works is using Microsoft drivers for these devices.
I even copied the drivers from one machine to the other - repeated everything above...
"Windows found driver software for your device but encountered an error installing"
And then the nail in my sanity
Try windows update....
Reboot
"Windows found driver software for your device but encountered an error installing"
but this time its different.
The device it thinks it cannot install is the generic MTP-PTP drivers (Photo Transfer Protocol -so am I getting somewhere)
so it still finds but cannot install.
The cameras are always found but appear as 'unknown devices' and cannot be accessed
Uninstall all USB/unkown again - reboot..
Same message and this time I've lost all the USB again.
Restore point to before Win Update gets me USB back again although I still have no cameras - so theres an update issue as well.
This has to be tied down to a file access/ registry problem although I'm loath to go cutting about without some guidance.
I'm no great believer in 'registry cleaners' unless anyone can point to a definitive/no ad's/sales version that really works.
As I said above, flattening/rebuild at this time is not an option - the user is not best pleased and I'm completley stumped.
If anyone has experienced(manu of you have) and fixed(still to find one) this issue please let me know how as soon as possible.
Chris

I know I am replying to an old thread - but I have the answer and resolved this error, and since this message comes up first in search results, and part of my answer came from this thread, I wanted to help someone else as this took an extra
12 hours and a lot of technical insight to resolve. See below for detailed explanation that others ask for above.
My original issue was that iTunes didnt reinstall. generating this error that said I am trying to access an unavailable network resource and to browse to find itunes64setup (again). This may partly have been due to me deleting old install version folders.
Research led me to completely uninstall apple products and reinstall per their instruction and fixed the issue with iTunes. see
Remove and reinstall iTunes and related software components for Windows Vista, Windows 7, or Windows 8 - Apple Support
The SAME error I had while updating itunes recurred while uninstalling it from my Windows 7 SP1 system...so I went to microsoft Fixit and attempted to correct and it properly uninstalled iTunes for me, which allowed the reinstall.
What didnt work was my USB web root/ root hub, which partly involved my older system and USB 1.0, and the delete/reinstall existing drivers with the c:\windows\winsxs folder as source of drivers (thank you Magon Liu!!!) which I had to figure out what/why
and how.
Then I had an intel chipset issue...my new Iphone wasn't recognizing in plug and play, and there was an error with installing the device drivers for my new iphone 6. Manual applications didn't work, even though a generic device showed in control panel -
device manager with a yellow !
Per above blog answer - I tried to remove and reinstall my USB controller or update the drivers (I have an Alienware M15 laptop - a few years old.) I discovered that the USB host controller - an Intel(R) 5 Series / 3400 Series Chipset family USB Enhanced
Host controller - (port) was not covered by current Intel chipset programs which are Series 6 and later, but did have an update (8/20/2009 v9.1.1.1020) that supported USB 2.0 (and therefore 3.0 backwards compatibility which as an issue with my new iPhone
and some USB thumb drives.) To find this I had to look at the Support - Downloads and Drivers - browse for drivers and somewhere found an option to look for older no longer supported drivers. I found infinst_autol.exe for my case.
Once downloaded I tried to install and failed. Found the log in C:\Intel\Logs and contains:
[InstallDev]
          [Device]
            Driver = C:\Users\DAVIDS~1\AppData\Local\Temp\IPMx7\WIN7\ibexusb.inf

            Installed INF =

            Using RegDeleteKeyEx
!!!         ERROR 0xE0000246: DriverPackageInstall generated an unexpected error
HERE'S THE ADDED EXPLANATION TO BRIAN'S POST THAT EXPLAINS THE SECURITY ISSUE:
This turned out to be an error for two reasons. First, after manually running the command in an "run as administrator" window (same error result), thinking it related to my anti-virus (turned that off/disabled firewall and A/V), and from this thread
granting my user administrative rights to files in an install folder and trying to reinstall inf files and drivers from C:\Windows\winsxs vs my copied infinst_autol.exe expansion (as found from log in C:\Users\David Samuels\AppData\Local\Temp\IPMx7\WIN7 folder).....that
there was an easier solution as the reason this error actually happens is a permissions problem.
To access the proper windows system folders - you have to be the TrustedInstaller service - not just in the administrator group...or you have to be the actual "Administrator" account. To become actual administrator on
your own laptop, Open a command window "run CMD.exe as administrator", then execute command
> net user administrator /active:yes
This creates a local PC Administrator account with no password. Coincidentally it has proper permissions to windows directories for installing drivers. Log in as this user, go to device manager and update the USB hub and any other drivers. if updating the
USB root - it doesn't replace it right away as the system cant disable the currently resident in memory "running" driver - you have to update, then restart the system, log in as administrator and repeat at the next lower layer that has issues.
Once completed - log in as yourself again and disable the administrator account in a command window with > net user administrator /active:no
This in my case enabled all my USB 2.0 and 3.0 devices on my originally only USB 1.0 laptop and everything else works properly again - I hope this helps many of you to resolve your own issues that were difficult to find and resolve and that got as far as
this thread. Good luck!
Regards,
Dave Samuels
