[0015] Please refer to figure 1 , figure 1 is a schematic diagram of the computer system 8 of the present invention. The computer system 8 includes a processor 9 , a motherboard 10 , an audio amplification circuit 11 , a motherboard built-in audio chip 13 , a first switch 15 , an expansion slot sound card 17 and a frequency isolation wall 12 . The built-in audio chip 13 of the motherboard is electrically connected to the audio amplifier circuit 11, and the connection between the two is determined by the first switch 15. When the motherboard 10 is turned on, it will automatically detect the adjustment status of the jumper in the first switch 15 to determine whether the sound effect generated by the built-in sound chip 13 of the motherboard should be amplified by the audio amplifier circuit 11. In addition, the motherboard The sound effect generated by the built-in sound effect chip 13 will be directly output from the sound source output hole 21 built in the motherboard. The ...
