PC audio not functioning

Or are you assuming they were installed as part of the OS?

Did you actually use a DRIVERS DISC after the OS had finished the installation process and rebooted?

Speaking of which WHAT IS your operating system anyway?

Assuming you have installed the Audio drivers (along with the Chipset drivers et al), have you checked in [b]Control Panel\Sound & Audio Devices[/b] to make sure your sound system is not muted?

Also check that the sound device is properly set for your onboard sound chip.

hi
if that's onboard soundcard does it need enabling again in BIOS?
cheers!

I can only guess at what has happened here but if this is a relatively new M'Board you will have Realtech AC97 Sound and this Driver needs to be installed before you Log onto the Windows Update Servers and download the very first update which is for allowing you to make contact with the Update Servers.

Realtech Drivers are not Digitally Signed by M$ so you need to install them prior to logging onto the Update site and they are generally installed separately to Windows to get full functionality.

For the location of the correct driver we need to know what the Hardware here actually is so we need to know the Make & Model of the M'Board or the computer and the OS that is being used. As different OS's use different Drivers.

If you installed Realtech Drivers after connecting to the Windows Update Web Site they will show installed but will not actually work. But you should first check that the Sound isn't [b]Muted,[/b] that the Correct Sound Device is actually listed in the Control Panel under Audio Devices and that you have the speakers plugged into the correct socket.

No Sound Output to Speakers or Headphones
No sound output can be caused by several problems. The following suggestions may resolve the problem of no audio output:

Onboard audio is disabled in the BIOS
The BIOS Setup program is accessed by pressing a function key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins. Go to the Advanced > Peripheral Configuration menu to make sure onboard audio is enabled.

Audio settings in the sound mixer are incorrect
Check your audio mixer software to ensure audio is not muted or the volume level is not turned too low.

The speakers or headphones may be connected to the wrong jacks
Make sure you connect all speakers to the correct jacks. If you connect them to line-in or microphone jacks, they won't work.

Audio drivers are not properly installed
Check Device Manager under the Sound, video and game controllers section for any errors associated with the audio driver. Reinstall the audio driver if necessary.

Audio to back panel is muted if front panel is connected
Check your audio mixer software for a setting that mutes back panel audio if you have plugged headphones into a front panel audio solution. Uncheck this setting to allow audio to both the back and front.

Sound Playback is set to wrong device
In Control Panel > Sounds and Audio Devices, go to the Audio tab. Check the default device for sound playback; there may be multiple selections. Select the desired device, either rear panel or front panel.

As you haven't mentions the Operating System check this link.
