Abstract
A system for testing audio of a motherboard includes a recording fixture and a computer. The recording fixture includes a recording device and a soundproof device. The soundproof device is configured for soundproofing the audio device and the recording device from environmental noise. The computer includes an output/input module, a comparing module and a displaying module. The output/input module is configured for outputting a first sound signal generated by the computer to the audio device to cause the audio device to generate a sound and receiving the sound generated by the audio device and recorded by the recording device from the recording device and transforming the sound into a second sound signal. The comparing module is configured for comparing the first and second sound signals. The displaying module is configured for displaying the compared result.
