Problems solved by technology
Second, if the signal cable is frequently replaced for a single sound card, the interface of the sound card will become loose, and the sound card will easily generate unnecessary noise, which will affect the test results
In addition, due to the increasing number of output interfaces in sound cards (such as 5.1 channels or 7.1 channels), the process of manual listening processing will be more time-consuming.

The invention relates to a sound card testing device and a method thereof, which is used for detecting whether a sounding port of a soundcard in a personal computer leaks sound. The testing device comprises a switching circuit and a switching unit. The switching circuit is electrically connected with the sounding port and the sound receiving port of the soundcard. The switching circuit comprises a plurality of transmission paths, which are used for receiving a first sound channel and a second sound channel. The switching circuit connects the first sound channel and the second sound channel to corresponding transmission paths so that the first sound channel and the second sound channel are fed back to the sound receiving port. The switching unit is electrically connected with the sounding port and the switching circuit. The switching unit is used for receiving the first sound channel and the second sound channel. The switching unit changes the transmission paths in the switching circuit according to a first switching message and / or a second switching message.
Description
technical field [0001] The invention relates to a sound card testing device and a method thereof, in particular to a testing device and a method for detecting whether sound leakage occurs between sound channels of a sound card. Background technique [0002] A sound card (Sound Card) has been an indispensable device in a personal computer. In addition to providing general music and film playback, the sound card is also used in sound input, such as sound input for recording sound and Internet voice. [0003] The existing sound card testing method is: install the sound card on a personal computer, and then connect individual audio channels (Audio Channel) to the corresponding speaker (Speaker) using different signal lines or connect the signal line to the corresponding channel The microphone input terminal, for example, the left channel output is connected to the left channel input. The sound card test program on the control unit will send test sound signals to each sound chan...
