'No Audio Output Device is Installed'

[Lystar]

I set up my brand-new HP Pavillion p6395a desktop yesterday. I wanted to download a programme for which I needed a Crack and Keygen and so on. I downloaded the crack and tried to use it, but it came up with "Access denied" and I freaked out so I shut down the computer (because, you know, -that's- going to solve everything). Of course, the stupid thing updated Windows (I have Windows 7). So I logged back on and tried to listen to a tute on YouTube, and was just thinking "oh lol I don't remember turning off the sound", but when I went to fix that, I discovered that I had the "dreaded x" problem and my less-than-24-hour-old computer was now useless as I was unable to use it to listen to lectures and edit videos, which are the two primary reasons I bought it.

What the hell? Honestly, I love HP to pieces, but if there's thousands of people around the world with the same problem, how hard can it be to fix it? Clearly they're losing a lot of business over this...

Is there anything I can do? I've tried uninstalling and re-installing the device driver. Zilch. I tried deleting the installation stuff from windows... No clue how to do it so that was a fail. I can't figure it out, I can click on them and view properties etc. but no idea how to delete them. There's a heap of fancy options but I'm no computer savvy, I haven't got a clue what to do and it's driving me nuts. I'm in Australia, not sure what warranties apply here but if it's not fixed by the end of the week I'm going to go get it exchanged, because this is disgusting.

If it was as simple as getting the solder joints fixed, everyone'd be suggesting it. My computer is only about 36 hours old and already has the problem, so I hope you're wrong otherwise HP has suddenly gone from a company that produces pretty decent and competitive products into a company about as useless as the white crayon.

PROBLEM SOLVED!

What was wrong:

I don't actually know, but from what a techno friend could figure (from my rather lacking explanations) was that the 64-bit system, being relatively new, wasn't compatible with the Windows updates, as these updates were primarily for 32-bit systems.

How did we fix it:

First, I backed up my system. You must do this unless you plan on losing everything. Beware that any software (programs) that you downloaded will be lost. Backing up your system only keeps files and documents.

CONTROL PANEL > (in search tab [top right corner]) BACKUP > BACK UP YOUR COMPUTER > SET UP BACKUP

So what we're doing is restoring the computer to its factory settings. This means that you will lose everything (except files you have backed up) so you MUST make sure that you can either download it (preferably for free) or you have the disk that it came on. If it's an antivirus program or MS Office or something with a limited number of users, and you can't run it because there are no "users" left, ring up the support and I'm sure they'll help you sort it out.

CONTROL PANEL > (in search tab) RESTORE TO EARLIER TIME > RESTORE YOUR COMPUTER TO AN EARLIER TIME > ADVANCED RECOVERY METHODS > RESTORE YOUR COMPUTER TO FACTORY SETTINGS

Then follow the prompts, and when you log back in you'll have sound again. This is a last-ditch effort so PLEASE try other things first, as you WILL lose everything.

Also make sure that you have followed the directions to the letter, because I don't want your computer freaking out and deciding that combusting is a more favourable option to working.

Other Methods:

Restart computer. On my computer, when it's restarted it shows a blue screen with the HP hands (I think). This is the bootup screen, hit F10. This will take you to a page which has all your computer's drivers, and the option to change the way they work. Scroll across (with the arrow keys) and down, look around until you find the Audio device, and change the settings from Auto to Enable. This is because the computer may be having issues automatically finding the driver thanks to the new updates, and enable sometimes seems to fix this.

Uninstalling and re-installing the driver hardware does work occasionally but not on this occasion.

If you use a laptop then it might be the solder joints, as they do tend to get very hot. If nothing works and you don't want to reboot, take it to a repair shop. They will usually charge between $20 and $50 where I live to sort out any technical problems, but you will also have to pay for any electrics, parts and the fixing of the computer.

Prevention:

Do not install Windows updates. As mentioned before it may very well be the case that the updates are not compatible. Do not allow computers to overheat, by giving ample space for ventilation. Use a riser for the laptop or a fan.

Good luck and hope this helps 🙂

AAAAARRRRRRRRRRRRRGGGGGGGGGGGGGGHHHHHHHHHHHHHHHH!!!!!

I have this exact problem and was told by HP tech support that I should buy a new laptop. My laptop an HP Pavillion dv9727 is only three years old. There is absolutely no fix for the problem, the hardware (sound card) is some sort of fossil apparently now and will never ever work unless you put a no-service pack OS and never ever update. ever.  Some HP tech people in other forums here keep blathering on about it being a simple matter of replacing the system card, 'cause that's totally the easiest solution for people who don't know what the hell that is or how to get one thats compatible. Literally I am going to throw my laptop out the window. After the frustrating experience I've had with this I WILL NEVER BUY AN HP AGAIN!!!! Are you listening HP? I'm very very angry with you. You make crappy crappy computers with crappy crappy components.  And telling me to buy a new computer? What am I the monopoly guy? I don't have any money. I am a student= broke as helllll.  If this is how they're gonna fix stuff I'm gonna buy an Apple, even though I'll have to sell one of my kidneys to get one.  At least my friends that have them have had them 6+ years. **bleep** HP you are not planet friendly.

Sorry that was not remotely helpful. I am not technologically inclined.  I'm just super hoping HP tech support reads this and knows of my extreme displeasure with them.

This happened to me today and I got it fixed today.

I am sure that it happened as a result of windows updates because I never do the updates and today is the first time I did it and right after updating the sound stopped working and there was an 'x' over the speaker in the bottom right corner that said "No audio output device installed" or something like that.

Solution( worked for my HP):

-Go to control panel

-Go to device manager

-Open sound video and game controllers folder

-Right Click Conextant High Definition Audio

-Select Update Driver Software

-"Choose Browse My Computer for Driver Software"

-Select "Let me pick from a list of Drivers on my computer"

-"Select "Conextant High Definition Audio" (There were two in my list with that name, I choose the second one)

-Select Next

You're done!!

Check and see if you have audio. 🙂

I was looking at another customer forum on here. and I found the solution. There is a conflict with the new version of flash by adobe... I have been having this problem for a little over 3 weeks. I have tried just about everything and was about to give up until I saw that post. I simply unistalled my version of flash and the flash plugin and restarted my computer and at start up came the sound. Hopefully that works for you all.

I forgot to mention I had verion 10.1 of flash.. after i uninstalled flash I reinstalled the newest version of flash which is 10.2

so I just did this so I will post again if I have any errors or no sound again.

Hi all,

the same problem with a borrowed HP Compaq 6730s, but I guess the reinstall didn't help.

I was running on win 7 while the sound stopped in the middle of playback (did this happen for anyone else?) and the red sign appeared.

From that moment the system showed no sound hardware at all. SoundMAX cannot be reinstalled because it says that the driver does not go with the current hardware configuration. (Although it's correctly downloaded from the HP website.)

The BIOS did not have ANY controls for the sound card from the moment I got the computer which was really strange.

I then tried to flash the BIOS to the new version which made the computer not to recognize the WIFI card!!! System information (F1) during boot said NO DEVICE INSTALLED and the on/off control in bios for the wifi card was missing!

The on/off BIOS control for audio appeared after this but had no effect on the system recognizing the sound card.

Then I chose to install Win XP and see if the sound would appear there. It did not.

So the first thing I installed was the chipset driver for XP (there is none for win 7 !!!) and after that the WIFI card appeard magically and now I'm writing you from wireless in win 7! The wifi control in BIOS suddenly appeared!

Still, no sound chip detected regardless of the BIOS settings and speakers nor headphone jack work.

The first problem with the devices on the computer started with webcam which didnt work for 2 days and now does.

This is oh so strange and frustrating.

Any ideas?

>  I chose to install Win XP

Then now you can use  dxdiag.exe  to test your sound.   E.g. I think a symptom like the one being discussed here only happened to me after updating to XPsp3.  So, I suspect it's a symptom of security/obscurity.   Anyway, in my case XP's dxdiag.exe  proved  that it is not the hardware because the sound from the Midi test was phenomenal!  Still Device Manager showed no drivers loaded.   WTH?   Unfortunately W7's dxdiag.exe does not have any of those Test buttons in it.  I don't know what Vista's looks like.

BTW notice I used past tense above?  I'm not using that computer any more.  The last thing I was getting into in trying to diagnose it was WMI.  More security/obscurity there.  If WMI had been allowed to work as designed I think there might have been some useful diagnostics generated by the drivers when they weren't started.

Also, to get as far as I did what I had done is make audiosrv a manual service.  Then I was able to trace it with ProcMon when I started the service.   That might have clarified what was wrong with WMI too.

FWIW your symptom of the sound just stopping "in the middle of playback" really sounds like something else than what the people here are probably seeing, e.g. yours seems like more of a hardware issue.   At least with XP you may have clearer diagnostics to use to determine that.   W7's troubleshooters seem useless, not to mention all the additional security/obscurity it involves.   ; )

Good luck
