No Audio Device Found in XPby Ruri Ranbe
Windows XP requires both a sound card and speakers or headphones to play back sound on the system. If Windows XP cannot recognize or detect either of these devices, it will display the error "No Audio Device" on the top half of the Volume tab in the Sound and Audio Devices Properties window.
Your computer's sound card interprets and converts digital audio signals into an analog signal that audio devices such as speakers or headphones play back. Some computer manufacturers integrate the sound card into the motherboard, while others include an expansion card installed to one of the computer's expansion slots.
The most obvious sign of a problem related to the audio device in Windows XP is the failure of the device to play back sound. Other signs include skipping or distorted audio or error messages appearing when you attempt to play sound.
Outdated or corrupt sound drivers can prevent your audio device or sound card from playing back audio. Certain settings in Windows XP can also force the operating system fail to detect your audio device.
Device Manager can look for and update your sound drivers to the latest versions available. Device Manager can also re-enable the sound driver if it is disabled for some reason. You can also check Windows Services to confirm that the Windows Audio service is not disabled.
In some cases, the connections on the side of the sound card or on the back of the speakers could have come loose. Reseating the sound card or reinserting the speakers into the audio output port on the rear of your system may restore your audio device in Windows XP.
