Abstract: Methods and systems provide automated testing of computer facilitated audio input and output devices. A tone is converted from a digital to analog signal and is sent to a sound mixing device. At the sound mixing device, the analog tone is looped back through a recording line to an analog to digital converter. The recorded tone is converted from a time domain to a frequency domain using a Fast Fourier Transform (FFT) analysis. The frequency, and if desired, the intensity of the recorded tone is compared against the known frequency and at the desired intensity of the played tone. If the recorded tone is the same as the played tone, the ability of the sound card to play the tone is designated as passing.

At the sound mixing device, the analog tone is looped back through a recording line to an analog to digital converter. The recorded tone is converted from a time domain to a frequency domain using a Fast Fourier Transform (FFT) analysis. The frequency, and if desired, the intensity of the recorded tone is compared against the known frequency, and at the desired intensity of the played tone. If the recorded tone is the same as the played tone, the ability of the sound card to play the tone is designated as passing. The FFT analysis results also may be utilized to calculate a signal to noise ratio (SNR), a total harmonic distortion (THD) value, a total harmonic distortion plus noise (THD+N) and a DC-offset value. Each of these calculated values may be compared against pass/fail thresholds for the played tone.

Abstract: Methods and systems provide automated testing of computer-generated displays. The proper functionality of a memory storage device on a computer video card and the proper functionality of software for generating computer-generated displays may be tested by storing a display image to a first memory device context while displaying the same image on a computer screen viewable by a user. The image displayed to the computer screen is captured into a second memory device context. The image in the first memory device context and the memory in the second device context are compared on a pixel-by-pixel basis to determine whether the two stored images match. If the second stored image does not match the first stored image, an indication is presented that the video memory of the computer memory card does not operate properly or that software responsible for displaying the image to the computer display screen is not operating properly.

Abstract: A method, system, and apparatus are provided for performing a diagnostic test on one or more managed system elements. The system includes a managed system element upon which the diagnostic test may be performed, a diagnostic setting object, and a diagnostics control module. The diagnostic setting object is derived from an industry-standard diagnostic setting object prototype and includes one or more properties specified by the prototype and a device-specific settings property identifying one or more settings for the diagnostic test specific to the managed system element. The diagnostics control module performs the diagnostic test on the managed system element and customizes the test according to the device-specific settings property in the diagnostic setting object.
