I'm trying to fix a friend's computer. He's somehow managed to disable/uninstall all audio drivers. (The speakers work, as testing with an Ubuntu Live CD demonstrates.)

Control Panel > Printers and other hardware > Sounds, speech, and audio devices > Sounds and audio devices

The Volume tab says "No audio device". The Audio tab says "No playback devices", "No recording devices", and "No MIDI playback devices". The Voice tab says "No playback devices" and "No recording devices". So something's wrong.

The Hardware tab, meanwhile, lists the CD/DVD drive, Audio Codecs, Legacy Audio Codecs, Media Control Devices, and a couple of video thingies, and for each one says "This device is working properly". The Device Manager says the same.

So something's misconfigured somewhere.

Just going to ask to make sure, have you tried safe mode/restarting your computer? –  chipperyman573 Aug 7 '12 at 19:50
    
@chipperyman573. Safe mode, no. Restarts, yes. As I said, I booted from an Ubuntu LiveCD. I'll try safe mode tomorrow. –  TRiG Aug 7 '12 at 20:05
    
What's your actual question? Have you tried reinstalling the drivers? –  techie007 Aug 7 '12 at 21:09
    
@techie007, there’s nothing to install drivers for. The Device Manager is not showing the audio-card at all anymore. –  Synetech Aug 7 '12 at 21:22
    
Enable Hidden Devices and check the Other Devices branch. –  Synetech Aug 9 '12 at 4:08

Things to try:

  • A System Restore to before.
  • If you can't do a System Restore, roll back the drivers for those devices.
  • If that doesn't work, reinstall the drivers for those devices.

Always get your device drivers from:

  • The card manufacturer's website OR
  • The motherboard manufacturer's website if onboard audio OR
  • The OEM's website for your specific machine if you have an OEM computer (HP, Dell, Sony, etc.).

Read the installation instructions on the website where you get the drivers.

Hope it helps.

System Restore may be necessary (if it is enabled) because the audio-card is no longer being detected at all. –  Synetech Aug 7 '12 at 21:23
    
System Restore fixed it, thanks. (It also, somehow, messed up the internet connection, but I managed to uninstall and reinstall that driver separately.) –  TRiG Aug 9 '12 at 23:19

32bit XP or 64-bit xp( 64 xp is a rare beast that has various problems with drivers ) , you should be good if you just re-install the drivers -in device manager you should be able to find out what sound card he has , or just look up the mother board manufacturer and get the audio drivers from that site .

Search for new hardware in device manager , google it if you don't know how to do this –  Keithsoulasa Aug 9 '12 at 2:58
    
That’s not very helpful. –  Synetech Aug 9 '12 at 4:07
