Re: no audio out put device installed
There are two likely causes for this:
1. You have an audio driver failure, simply install new audio drivers by determining what kind of sound card you have installed in your computer using device manager and then going to the manufacturer's site to download the newest drivers. Install these, reboot and you should be off to the races.
2. Your onboard sound has failed. Laptop motherboard failure is a problematic issue that could quite easily be the case. Repairs for this kind of damage are covered under warranty but else they are expensive to repair.

First check if the driver is installed or not removed follow
My computer right click ,properties, device manager and look for audio devices if present it's ok any yellow sign next to them installed devies means issue with driver or not properly installed
Control penal double click on te audio sign and underneath there is two check lines one if them is for showing Audubon logo in the time tray click to show it there and then it's always gone b there unless u remove it
Right click on the speaker icon in the task bar, lower right hand corner of the screen.
Select "Adjust Audio Properties."
In the popup box, go down to "Speaker Volume." Click "Advanced"
In the new pop-up, make sure that "Laptop speakers" is selected. Click all the OKs you need to in order to establish that setting and clear out of "Adjust audio properties."
Now you SHOULD have much better sound from your speakers.
For some reason, my D250 keeps defaulting to "Stereo headset" which produces much lower volume sounds when a headset is not inserted. So low that you can't watch and hear a video through the speakers and understand what is being said. Once you switch to "laptop speakers" you'll be able to hear stuff. It won't be high volume, these things just don't put out high volume, but it will be reasonably audible, if this was the problem.
The most likely causes for this is:
External Speakers not turned on.
Turn them on...
Driver for the sound device isn't installed:
If you see the little speaker icon down the bottom right hand corner of your screen (near the clock), your sound card device driver is working well.
If it is not visable, the sound card device driver may or may not be working.
Go into the start button, select settings (if available), then control panel, Sounds and Audio Devices.
Select the Audio tab
Ensure that you have a 'default device' set.
If you get any errors when going into the sound and audio devices tab stating that you have no audio devices installed, then its most likely a driver issue.
In this case, refer to your local computer shop to have the audio drivers installed.
Driver for the keyboard sound function not installed or not running.
Reboot then test it.
Reinstall the driver, test it.
go to www.hp.com. on the bottom of the laptop there is a white sticker. find the P/N # and get ther first 7 numbers/letters. on the hp website there is a search box in the to right hand corner, type that number there. it will bring you to a page to select you model or to download drivers.
