摘要： An apparatus and a method for testing a sound card are applicable for detecting whether a sound leakage problem occurs to a sounding interface of the sound card. The testing apparatus includes a switching circuit and a switching unit. The switching circuit is electrically connected to the sounding interface and a sound-receiving interface of the sound card respectively, and has a plurality of transfer paths. The switching circuit is used to receive a first and a second sound channel, and to connect the first and the second sound channel to corresponding transfer paths, so as to transmit the audio signal back to the sound-receiving interface. The switching unit is electrically connected to the sounding interface and the switching circuit, for receiving the first and the second sound channel. The switching unit alters the transfer paths in the switching circuit according to a first and/or a second switching audio signal.

摘要： An apparatus and a method for testing audio jacks of a sound card are applicable for detecting whether at least one audio jack of the sound card in a personal computer (PC) sounds normally. Each audio jack provides at least one sound channel for transmitting a sound signal. The testing system includes driving circuits and a plurality of light-emitting units. The driving circuits are electrically connected to the sound card and an external voltage source, and used to change a current transmitting path according to the received sound signal. The light-emitting units are electrically connected to the driving circuits, and receive the current generated from the driving circuit, such that the light-emitting units emit lights. A sound channel to be tested is selected first, and a sound signal is sent to the sound channel. After the testing apparatus receives the sound signal, the light-emitting units emit lights.
