  • Audio control circuit and associated control method
    Patent number: 11929722
    Abstract: The present invention provides an audio control circuit comprising an USB interface and a processing circuit is disclosed. The USB interface is used to connect to a host device, and the processing circuit is configured to perform enumeration with the host device via the USB interface, and the processing circuit is further configured to determine if the host device operates in a BIOS stage or an operating system stage to generate a control signal according to packets of the enumeration. When the processing circuit determines that the host device operates in the BIOS stage, the processing circuit generates the control signal to enable a de-pop circuit; and when the processing circuit determines that the host device operates in the operating system stage, the processing circuit generates the control signal to disable the de-pop circuit.
