Problems related to audio devices usually become apparent when there is no sound output from a computer. Initially, there can be a number of possible explanations for this, and it is always wise to check the actual physical components within your computer that produce sound, or external devices if your computer is plugged into a speaker or sound system. Sometimes connection issues can cause problems in this area, and a lot of hassle can be avoided by checking these first.
However, once any problems with such devices have been eliminated then this can be attributed to a driver difficulty, with the computer evidently unable to recognise an attached audio device for some reason. Aside from your computer having no sound, when you open the Sounds and Audio Device Properties window from the Control Panel, the audio features options will be unavailable. Furthermore, the the text “No audio Device” will be shown on the desktop.
Firstly, manually enabling the Windows Audio Service can correct any audio problems. In order to do this, click Start > Run and enter ‘services.msc’ into the field. From the services window right-click ‘Windows Audio’ and select ‘Properties’. In this next window select ‘Automatic’ from the ‘Startup’ dropdown lists, and click ‘Start’. If any of these options are greyed out, you can assume that the Windows Audio Service is already in operation.
If the previous is fruitless, check if the audio device is enabled, and if not then enable it.
- Click Start, right-click ‘My Computer’, and select ‘Properties’.
- Click the ‘Hardware’ tab, and then select the ‘Device Manager’ button.
- Scroll down the list which appears, and select the ‘+’ symbol next to ‘Sound, video and game controllers’.
- Under the ‘Sound, video and game controllers’ category, right-click any item that has a speaker icon with a red X and select ‘Enable’.
- After all sound-related items are enabled, close Device Manager.
If this doesn’t work, you can attempt to reinstall your computer’s audio driver. Most PCs use either Realtek Audio Codec or Creative Audigy software. If you’re unsure of which your machine uses, this can be found within the ‘Sound, video and game controller’ of Device Manager.
Next you need to download and install audio drivers from either Realtek or Creative’s support site.
Finally, if none of the previous steps works, a system restore operation may resolve the problem.
