'No Audio Output Device is Installed'

[wtw11171]

I guess if you want sound the only thing to do is attach the a few stick of dynamite to the laptop light and run. I'll bet there will be a very loud sound coming from the device then!!!

where is the solution, no link is there

There is no known solution to this problem as yet - I have had the same issues that most people have listed here and near enough tried every "solution" listed.  It is not due to overheating (all laptops will overheat, it doesn't affect the sound device) and doesn't appear to be a driver issue since people have updated, and reinstated these if the sound device will let them, its not a motherboard issue or disc drive issue, but is most likely related to a recent windows update.  I have a case number with HP who are working on it, they also read the forums listed so know the issues going on (note this issue is of high topic right now) ....... supposedly they are working on it!  Watch this space (and for those of you with lots of money go buy your Toshiba or Mac or whatever floats your boat!!)

This just happened to me two days ago. Now I've tried ALL of the "solutions" here and non of them are working. I've had problems with my comp for the last year to be honest. I guess its time to buy a new one. First my batteries stopped working, then my usb ports, the fan (cant keep the computer on "high performance" or it gets to hot and switches off) the cd-rom quit..And my network card is busted also. I can only use wireless so I had to buy a router to get my internet working again 🙂 And to top it of now the sound! I still would like to try fix it so I can keep it about 3 more months before I go back home to Swede and buy a new one...prolly not a HP to be honest after seeing these forums with no solutions! But hey, still looking forward to the solution! 🙂 I will have this thread as my starting page and see what happens!

Same problem, for months now. 

Hp Pavilian dv2000

Windows vista 64 home permium

AMD Turion64

No Sound option in device manager.

Worked fine for years. Restarted after an update one day, no sound. Red circle, white X over sound tray. Tried a few things. Reformatted, got sound back, worked throught the updates, lost it again.

Tried everything I've read on all the different forums/ blogs. nothing worked.

I turned the audio system off, then back on. D/led all the drivers and then tried reverting to the old ones. 

I d/led new BIOS and upon my restart I had sound... but that only lasted a day.

Back to Red circle, White X, No Audio Device is installed.

Why isn't this fixed???

[dlkn]

yes this problem still exists!

i too have done "everything" (un intstall, reinstall, update, roll back, restore etc...) so the first restore worked after un installing etc. then the auto update and lo and behold, no more sound! this is not a hardware issue, this is some sort of io or irq opr software update conflict!  you would think that this would be addressed by MS and HP. GRRRR!!!!

so i will continue to check in for some sort of solution.

ranting!

Same Problem! I have tried EVERY solution in this thread and sometimes I can get the sound card to work, but as soon I restart it's back to the "NO AUDIO DEVICE IS INSTALLED." What a pain! NEVER buying HP again.
