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.
