"No Audio Output Device is installed." vista sound problem Attn. HP

I've been seeing several posts attempting to address this issue but I don't think anyone quite understands how deep it goes... therefore, I'll try to give as many details as possible.
About two weeks or so ago the sound on my laptop started to behave strangely (crackling, device not found here and there, etc.). This occurred after I a) flashed to the (at that time) most recent version of the BIOS (I believe it was F.31) and b) updated the chipset drivers. My reason for doing this was that the fan in my laptop was rediculously loud (BIOS update) and that my ethernet adaptor suddenly didn't seem to work (after I updated the BIOS).
After I made those updates the sound device seemed to just completely dissappear. I have a HP Pavilion dv6700z CTO Entertainment Notebook PC, p/n. gw772av.
I even went so far as to wipe the hard drive and do a full system recovery... after which the sound card device for maybe a day or so then after a restart would be non-existant, then would re-appear. But at this point it is gone, device not found, can not find even in "Add Hardware".
The only "common denominator" here is that the BIOS I flashed to is still the same. Other than that, all drivers were set back. I can't particularly remember if I re-installed those same chipset drivers after but I believe I did.
If anybody out there has the slightest clue (hint hint HP), please respond to this thread.
Thanks in advance,
Travis

This goes deeper than you think. I have an HP Pavilion dv6000. It arrived with Vista installed. It has never, not ever, supported the external speak or headphone jacks.
I have speakers (externally powered) and headphones what work fine on all my other computers, including my newer and more expensive work HP laptop.
Most of the "help" on new external sound directs you to something like "Figure 2: Playback Sound Window and Mixer Showing Multiple Sound Devices." I have one device, the realtek internal speakers, and they cannot be configured beyond changing the fade from left to right.
Why is there not a useful FAQ on this issue?

HP Pavilion G6 -1150SD - No audio output device is installed

NO Audio output Device is installed as well as NO sound, video, or game tab in the device manager

Here is the issue I had with with my Compaq F700 series laptop. The sound was working one day and then not working the next. Over the volume icon there was a big red X and the warning that No Audio output Device is installed. I also found that there no longer was the sound, video, game tab in the device manager. It had gone missing.
I couldn't use most of the fixes as they require having the sound, video, game tab available and this tab was, as I said missing. I tried reinstalling the sound drivers from the manufacturer’s website as well as using the driver re-install, but at each attempt it would fail as a result of not having any audio devices installed on the computer.
I tried doing the system restore and rolling it back but the problem didn't get resolved. What eventually worked was restoring the system to a MUCH earlier date, like a month prior to the problem. When the restore finished the sound was still not fixed. HOWEVER, the computer OS (WINDOWS 7) needed to re-install a bunch of updates and after the updates were installed, everything was working. I suspect that the original issue was a bad update (the updates didn't install correctly) and that by rolling the system back to a time prior to the bad updates and then re-installing the update was the fix.
With that said, if the restore option doesn’t work or can’t be done I would try looking through the add/remove programs in the control panel and uninstall the most recent system updates, then restart computer and let the updates re-install.
Good Luck

Only option that I see in the BIOS is under Security. Audio Device: Hidden or Available. It was set to available and I left it at that. Still no audio.
Really? Nothing? This computer is one year old. Absolutely no reason for this to be happening. What a joke.

Straitstrider67, welcome to the forum.
What is the make/model of the speakers that you are installing? This will help me understand how they should be connected. There are several ports for connecting the speakers on the Back I/O. Once I have the information that I requested, I will see what I can do to help you get them up and running.

I have a HP Pavilion dv9700 / dv9910us running Windows 7 Ultimate 64 upgrade from Windows Vista (64) - I cannot fix: "No Audio Output Device is installed."

Thanks Paul for your quick response.
This Laptop was upgraded from Vista (64) to Windows 7 Ultimate (64). It's a laptop so no sound card.
The audio controller is a: "Sound, video and game controllers" and the driver was originally a "Conexant High Definition Smart Audio 221".
I down loaded the latest Vista 64 driver: "sp37816 Conexant High Definition Smart Audio 221 V 4.31.1.0" even though I am running Windows 7, it was sated somewhere that it would work, I get an error "Driver Installation Failed: Could not find the device for this river.

Audio Problem. says computers muted/ no audio output device is installed. works on start up

I have a HP pavilion dv6500 notebook, windows vista 32-bit.
My computer was recently wiped and was given to me by a friend. he told me the computer needed a new sound card and that the sound never worked.
However, when i first started my computer I had an update and a sound driver was installed.
I put on a movie, the sound worked flawlessly, so I know the drivers, audio output device and soundcard are all installed correctly, but after a minute or so of watching the movie my sound cuts out, the speakers icon shows it is muted, and won't allow me to change the volume, when i scroll over it a message pops up that reads "no audio output device is installed".
sometimes when I shutdown my computer and restart it, my speaker Icon appears normal, and I can listen to music or watch a music video and the sound works again, but after 30 seconds to a minute or so, it does the same thing and wont work anymore.
I dont know what to do. I have tried to use the site to scan my computer for missing files or drivers but it just said that my computer isn't the model i specified (which it is) and that I have an expired warranty. which shouldn't matter if all i need is support.
I work with music and need to use programs like Protools or Logic Pro but I cant do that without sound so haven't installed those programs on my HP yest. PLEASE HELP.

I'm having the exact same problem. The problem arose randomly, and when I checked my computer's devices there was a device in "other" called 'High Definition Audio Bus' that had been installed (without my knowledge) right before my computer lost sound.
What had happened was my computer was running extremely slow all of a sudden and so I restarted it and when it restarted I had no sound. Because this device was installed on my computer immediately before the sound stopped working I assumed it was the cause of the problem and uninstalled it.
It didn't solve the problem, niether did installing the driver you posted a link to, it just posted an error message that read: "Could not find the device for this driver"
I'll try reinstalling the necessary drivers for my computer, which leads to my next and much more insignificant issue: How do I find the product name of my laptop? it's an HP Pavilion g series, and it lists the serial number and product number but from this list http://h20000.www2.hp.com/bizsupport/TechSupport/ProductList.jsp?lang=en&cc=us&taskId=135&prodSeries... I have no idea which laptop is mine. How can I find out?

No audio output device is installed - Satellite C855D-S5950 - Windows 8 64-bit

Toshiba laptop
Model: Satellite C855D-S5950
P/N: PSCBQU-03G03E
OS: Windows 8 64bit
RAM: 4GB.
Hello,
I have my friend’s Toshiba Satellite C855D-S5950 with Windows 8 (64bit) that about a year old. Some months ago the sound stopped working. He asked me to take a look at it. I have researched this issue and found others have encountered his problem as well.
Currently, the sound icon has a red x, “No audio output device is installed.”
Things I have tried so far to try to fix this:
I went to the Device Manager > Sound, video and game controllers. I have "Realtek High Definition Audio" listed with the little yellow caution icons on them. I have tried to disable, then enable it. I have tried to uninstall the sound driver from the Device Manager. I would restart the laptop, and let the driver reinstall itself, to no effect. I have tried downloading the latest drivers from the Toshiba website. I have tried un-installing the driver while in safe mode from the Device Manager. As well as from Programs and Features. There were no positive change to the audio though, still the same message. The Realtek driver won't finish installing and throws the error: "Install Realtek HD Audio Driver Failure!! [Error Code: 0x000000FF]"
I have gone to Control Panel > Sound, under both the Playback and Recording tabs, it says "No audio devices are installed."
My friend was previously unaware of how to restart or shut down his Windows 8 laptop (as was I until I started investigating this problem for him). I mention this because there are no useful System Restore points to go back to for him.
I have also tried Using the Toshiba Application Installer as well to re-install the driver after un-installing the Realtek Audio driver from Add/Remove Programs. I went to Desktop Assist >Support Recovery > Toshiba Application Installer.
Realtek Audio Driver 6.0.1.6743
It loads most of the way then I get:
"Install Realtek HD Audio Driver Failure!! [Error Code: 0x000000FF]"
I have also tried the following links for additional troubleshooting:
http://forums.toshiba.com/t5/Audio-Sound-Knowledge-Base/Windows-8-Troubleshoot-no-sound-with-Windows...

It was also suggested in the above thread I remove the Microsoft UAA Driver, but could not find this driver on my friend’s system.
Plugging in headphones, toggling the speaker volume controls on the keyboard has had no effect.
My friend has also misplaced his install discs, so I am looking for any solution which does not require the install discs.
Any help would greatly be appreciated.

Recovery media is created from the hard drive. You can make it using Toshiba Recovery Media Creator. You can also perform a full system reset to factory defaults using the information on the hard drive without using external recovery media. That sounds like the best course of action now. To do so, use Windows+C > Settings > Power > SHIFT + Restart > Troubleshoot > Reset your PC.

No Audio Output Device is installed error message

I have a hp pavilion m6- 1045dx and when I turned it on I noticed there was no sound and the speaker icon next to the clock in the bottom right corner had a red "x" next to it. I tried pressing the mute button, up volume, and down volume buttons and that didn't work. I've tried power cycles, uninstalling and re-installing and even downloading new drivers, checking for software changes, and checking to see if software and things pertaining to this problem were up to date (windows said yes). My frustration level is through the roof and I'm ready to get rid of this laptop. Can someone please help?

Hi ALima,

No Audio Output Device is installed

Hi,
I have a brand new Pavilion Sleekbook 14-b029TU running 64bit windows 8. product no: c7e65pa#abg.
to the right near the speaker is a red cross. when i hover the mouse over it it says no audio output device is installed. i followed all the ideas on the internet, all the trouble shooting on these forums and on hp help to no avail.
also, when i requested online support, my model does not come up in the options so i couldn't get help that way.
So if i right click on the speaker and bring up the sound options and look into them, they say that there is no audio output.
i went into device manager as suggested by hp, went to hardware, sounds, and checked and under sounds there is:
intel (r) display auto
high definition auto drive
they both say they are enabled.
what's the problem?
please i've tried so many options. i updated. turned off and turned on my computer etc etc to no avail.
i'm losing my mind. this is a new laptop. i don't understand why the hell this is not working???
PLEASE PLEASE HELP

What you are describing seems as if the sound device mute might be enabled.
Hold the Fn key down and tap the F11 key once. That should enable sound and remove the red cross in the systray over the audio icon.
Best regards,

DV6 - 3203TU, No Audio Output Device is installed

Product: DV6 - 3203TU
Product ID: LG225PA#ABG
OS: Windows 7 64-Bit
Hi folks!
The sound on my laptop stopped working, there were no updates of any sort prior to the occurrence, but now the volume control has a red x in the icon and reads " No Audio Output Device is installed". Troubleshooting reveals nothing (it can't see a device to troubleshoot).
I tried installing the sound drivers for the DV6 - 3203TU but the installer reports that the 'hardware detected is not compatible with this IDT audio package'.
In order to make sure that the DV6 - 3203TU was the right device (it's on the sticker beneath the battery) I tried to use HP's autodetect software. It did not find an HP PC, just my HP printer.
I'm not sure what to try next.
Any help would be very appreciated, thanks in advance!

Hi tristh1,
Thank you for your query, I will do my utmost to assist you.
I grasp that you have lost the sound. You have tried installing sound drivers, but you got a message that"the hardware detected is not compatible with this IDT audio package". You are unsure of the model number and were unable to confirm it. Here is a link to How Do I Find My Model Number or Product Number? so you can verify the model.
Here is link to No Sound from the Speakers (Windows 7),to aid in resolving this issue.

Missing completely from device manager on an integrated component typically indicates a hardware issue. It's not something that could have a loose connection as it is soldered onto the motherboard.
If you want to be absolutely 100% certain that it's not a software issue, you could perform a full HP system recovery back to factory conditions. That would confirm without any doubt whether it is a hardware or software issue, but it is more than likely a hardware failure based on the behavior.
However, what is the hardware ID of the base system device?
This can be retrieved by opening the device in device manager and navigating to the details tab and changing the property to hardware IDs. This should help identify exactly what the base system device is.

"No audio output device is installed" on Satellite C655D-5120 running Windows 7 64-bit

Ever since I installed Windows 7 Professional 64-bit on my C655D-5120 laptop, I keep getting the message "no audio output device is installed." I have tried all the suggestions I have been able to find on the internet to install any audio output device to correct this situation but without any success whatsoever. If I go to Control Panel and click on Device Manager, there is no entry for "Sound...." so there is nothing to delete there to start things over again. So, does anyone have some new suggestion that I should try?
Solved!

To answer your question, it's a rather long story. I bought the computer used and already out of warranty more than two years ago and sent it to the Philippines with my son to give to a friend there. Because it did not get forwarded, it just sat unplugged for a very long time, likely more than a year. When I suggested that my son plug it in, he informed me that the battery had failed, the keyboard was unreliable, and there might be problems with the hard drive. So when I visited the Philippines in March, I took along a newly purchased battery, a newly purchased keyboard, and a spare hard drive that I already had. In the process of swapping out the keyboard, something slipped and it broke loose the on/off power socket from the motherboard. So I just brought it back to California in April. When I could not repair it myself, I took it back to the man from whom I bought it. He discovered that there was something else seriously wrong with the motherboard and replaced it and the entire lower half of the case, which it turns out was not an exact replacement. The trade unanticipatedly converted my C655D-S5120 to a C655-S5082. When I attempted to boot the computer, it kept asking me for the HDD password, which I had never set or changed and therefore was unknown to me. What caused this to happen I do not know, unless it was because the internal battery completely discharged. Internet research convinced me that this locked HDD was now trash, and I replaced it with a spare WD HDD that had been previously wiped clean, loaded a new installation of Windows 7 64-bit onto it, and started using it again. All research I have done since then and the multiple attempts I have tried indicate that this C655 has no functioning hardware audio device installed and therefore trying to load an audio driver is futile. Not knowing the history of the C655-S5082 replacement definitely complicates things. I have resigned myself to using it without any audio capability. (It is not my only computer.) Because I am severely hearing impaired (I'll be 78 later this year), functional audio is not particularly necessary anyway. So I believe that this case can now be considered closed, even though not to my complete satisfaction.
