My unboard sound card is not working. In the sound and audio devices properties window it shows no audion device. How do I get this to work?

enable the o board sound card from bios

Run a Windows Update, check to see if there is an updated audio driver, if not go into the device manager and remove all of the audio devices, reboot.

That should resolve your issue.

Let me know if it doesn't ;)

The sound card features might be turned off and causing Error Code: 88780078.

To activate these "features":
1)control panel
2)sounds and audio devices
3)Hardware tab
4)sound card should be listed... highlight... Properties
5)Properties tab
6)Audio Devices
7)highlight sound card and click Properties
8)If audio features are disabled... select "Use audio features on this device"
9)restart computer

1.
Check the speaker connections - take the plugs out and put them back.
Make sure the speakers get power.
Test the sound with headphones.
If it is a Laptop be sure the speakers are turned on (Usually an Fn function key).

2.
Load a system restore point from a date before the sound problem started.

3.
Has the audio service been started by Windows?
Click Start > Run > type services.msc - then click OK.
In the new window - Scroll down to "Windows Audio", right-click on it and select Properties.
Another new window - set the startup type to Automatic, click Apply and then click Start.

Have a look in "Play control" and any other sound mixer you may have installed to check if the sound is muted.
Go to Control Panel >> Sounds and Audio Devices.
Check to see if your sound card is listed.
If no audio device is detected proceed to step 5.

Be sure the Volume is turned up (at least half way).
The MUTE box should not be checked (go to the advanced window and make sure that nothing is muted).
Select the proper speaker settings under speaker settings advanced tab.
Set the speaker setup settings accordingly.

Is your sound card the default playback device?
Right click the speaker icon next to the clock >> Choose "Adjust Audio Properties".
Click on the Audio tab and select the correct device.
If you make any changes - click Apply, then OK before you close the window.

If you use another type of audio program, please refer to that program's trouble shooter for diagnostics.

Creative Sound Card owners can try this:
Click Start >> Programs >> Creative >> "Sound Card", for example Audigy >> Creative Restore Defaults.


4.
Check to see if the sound card is properly installed in the Device Manager.

Right click My Computer >> Properties >> Hardware Tab >> Device Manager >> in the "View" menu - click "Show hidden devices".

If there are yellow or red "marks" next to the audio, "Microsoft Universal Audio Architecture (UAA) Bus" or an unknown device - install drivers (see step 6).

If Windows does not detect an ONBOARD (Integrated) sound card >> Check to see if it is ENABLED in the BIOS (Setup).
If Windows does not detect a PCI sound card (an Added sound card) >> Shut the computer down, disconnect power. Take the sound card out and put it back again - if possible, use another PCI slot.

5.
Install available Windows updates, including DirectX.
Go to Start >> All Programs >> Windows Update.

6.
Installing drivers:

6a. Install the chipset driver first >> Reboot.

6b. If a "Microsoft Universal Audio Architecture (UAA) Bus" is present in Device manager >> install the driver >> Reboot.

6c. Uninstall old sound drivers:
Check in Add/Remove Programs in the Control Panel for an Audio device driver (i.e. AC97).
Go to the Device Manager and uninstall the driver (Right click on the device >> uninstall).

Install the sound driver >> Reboot.

The drivers to install can be found on a CD that came with the computer/motherboard/sound card.

Here is the link to the page for the driver for your audio. once you install this you should be up and running again. Hope this helps!!

uninstall the ati sound utility, these video cards have a built in high def audio chip for sound thru hdmi

You will find the correct drivers by browsing to Compaq's home page and submitting the model number of your Compaq

Vista: Windows Control Panel / Hardware and Sound / Sound / Manage Audio Devices
or Right-click speaker icon in system tray and select "Playback devices"

Note: The audio devices you want to use MUST be present in these Skype device lists. If they are not, check the device connections and driver installations again.

2. Microphone and Speaker connections

Check if your mic (pink) and speaker (lime) jacks are in the proper sockets (it is easy to reverse them) and fully inserted (they sometimes stick only partially inserted)
If your microphone or headset has a “Mute” switch, make sure it is not on
If your speakers or headset has a volume control, make sure it is turned up
For test only you can use an earphone instead of microphone (really)! Just unplug the microphone, plug the earphone into the microphone jack, and talk into your earphones. (I know it sounds silly, but it might tell you if your microphone is defective)
A standard microphone plugged into Line In will NOT work.

3. Check audio in Windows.

XP: Start / All Programs / Accessories / Entertainment / Sound Recorder

Vista: Start [Orb] / All Programs / Accessories / Sound Recorder

Make a short recording with the microphone; you should see the level meters moving as you speak. On Windows XP, you can then play back what you recorded.

4. Once done, test with Skype Test Call (echo123).

all the options in sound and audio device properties are in active no sound is heard

check for devices in "other devices" in Device manager
