No Audio Device - Tried everything!
Hi,
I have machine running on Windows XP with SP2. This morning I had a boot error which required me to repair via the Windows CD. This all went fine however I now cannot get audio from my PC.
When I go into Control Panel/Sounds And Audio Devices it says 'No Audio Devices'. I have googled this error and have been trying various solutions all day with none of them working.

I have the Realtek High Definition Audio setup, and I have removed all the existing drivers etc and reinstalled via the Motherboard startup CD. This has not worked. I have also tried getting the lastest drivers from the Realtek site, this has also not worked.
Basically, I have reinstalled every driver etc included DirectX from my Motherboard startup CD and nothing is working. All the software for Realtek High Definition Audio installs fine, but it's just not picking up my Audio Device.
Can anyone help, as I'm looking at my Windows XP cd now hoping I won;t have to reinstall just to fix this
Thanks in advance

Is this a pre-made computer, or did you build it yourself?

It was a pre-made barebones unit which I just added a hard drive to

Have you tried searching the manufacturer's website for proper drivers?

Open up Device Manager. What do you see under Sound, video and game controllers? What happens when you run the Add Hardware wizard? And let's make sure of something: are you sure that your computer either has a sound card installed or integrated audio?

In Device Manager I have the following:

Microsoft UAA Function Driver for High Definition Audio - Realtek 880
Audio Codecs
Legacy Audio Codecs
Legacy Video Capture Codecs
Media Control Devices
Video Codecs

When I install the Realtek drivers from either the site or disc the above 'Microsoft UAA Function Driver for High Definition Audio' chages to 'Realtek High Definition Audio Output'

Also, the other items listed were added after going through the Add Hardware wizard.

I think I have intregrated Audio as opposed to a Sound Card. I've checked my BIOS settings and cannot find anything out of place in there

That is your audio device. And going by what you wrote, I assume you do not see any alerts there.

Make sure that your speakers in good working order, and that they are powered on and plugged into the proper jack. Open your audio control panel and make sure that nothing is muted.

Nope, no alerts.

Speakers all fine, however cannot access the audio control panel as it disppeared when this problem began

I'll keep playing around and see if I can find a solution!

Found one!!

Many thanks to efi from www.d-a-l.com


>1. From Device Manager (be sure to select View/Show hidden devices), find the 'ISAPNP

This just worked for me. Activated all my Realtek HD Audio devices!

Many thanks Curly for your help!
