For computers running on Windows operating systems, corrupted sound drivers are almost always the cause of an audio output device that fails to register with the system. To fix this, users should navigate to the machine's device manager program and enable any disabled sound drivers. If this does not provide a solution, a user should uninstall the corrupted drivers, go to their official distributing source, and install the most recently updated version of a particular device's sound driver.
To translate digital data into sonic waves capable of being heard by humans, computers require an audio output device to be connected to the machine before any sound can be generated. Audio output devices generally take the form of external adapters, sound cards or circuits integrated into the machinery itself. Sound card style audio output devices usually provide standardized 3.5 millimeter audio input and output jacks installed by inserting the device into an expansion slot on the motherboard of the computer.
External audio output devices are often installed by simply connecting the male end of the audio device's wire to the appropriate female port on the computer. Other possible sources for audio output device installation problems include faulty sound jacks or motherboards and corrupted operating systems.
