Claim 9:
10. The control method of claim 6, wherein the step of when it is determined that the host device is operating in the BIOS stage, generating a control signal to enable a de-pop circuit, and the step of when it is determined that the host device is operating in the operating system stage, generating the control signal to disable the de-pop circuit comprise:
when it is determined that the host device is operating in the BIOS stage, generating the control signal to enable the de-pop circuit to block the output audio signal from being transmitted to a speaker or lower the volume of the output audio signal; and
when it is determined that the host device is operating in the operating system stage, generating the control signal to disable the de-pop circuit, so that the output audio signal is directly transmitted to the speaker.
