I see that there are a lot of people here that are having the same problem. This is what I found that restored my sound
- Under 'Sound and Audio Devices' on the Control Panel: 'No Audio Device' under the 'Volume' tab
- Device installed properly in Device Manager
- Some audio in some programs (I was able to get it to work properly in Windows Media Player before a complete fix by going to Tools -> Options -> Devices -> Speakers -> Properties -> Select your sound card)
- Various driver solutions (new, old, from manufacturer, install CD, etc.) don't work
Other symptoms I experienced which other seekers might find useful
- Using run -> dxdiag: go to the 'Sound' tab and 'Test DirectSound' My results were 'DirectSound test results: Failure at Step3 (DirectSoundCreate): HRESULT = 0x8878000a'
- It didn't matter what sound card I used, onboard or an add-in PCI card
- The BIOS settings for the onboard sound were correct and disabled when using the add-in PCI card
- WMP would return an error (before I used the above fix) of C00D11BA
The solution that fixed it for me:
1 - run -> services.msc
2 - Find the 'Windows Audio' service
3 - If it's set to 'Manual' or 'Disabled', there's your problem. Right-click on it to pull up the properties and set it to 'Automatic'
(If the service was set to 'Manual', it's an on-demand setting which might explain why some users were able to use sound after a driver install [flicks service 'on'] but not after a reboot [no installation program to flick the switch] It would explain Creative diagnostics getting sound too)
4 - Start the service and hopefully you'll get sound
I too am having an issue with my sound. I followed the instructions given but when I click start to start the service I'm given an error message which says windows could not start windows audio service on local computer. Error 1059:Circular service dependency was specified. Please help, I'm ready to toss this computer
