1. A display apparatus, comprising:
a display;
a user input interface configured to receive an instruction input from a user;
a plurality of HDMI interfaces configured to connect to a plurality of external devices;
a power management module configured to at least control the display to power-down or power on to cause the display apparatus to enter into a standby state or a power-on state; and
a controller in connection with the display, the user input interface and the power management module and configured to:
while the display apparatus is in the standby state, in response to a power command input from the user, control the power management module to cause the display apparatus to enter the power-on state from the standby state,
in response to determining that there is an audio device among the plurality of external devices, control the power management module to cause the audio device to enter the power-on state first, and then control the power management module to cause other external devices among the plurality of external devices except for the audio device to enter the power-on state;
wherein the audio device is determined by a logical address allocated to an external device;
wherein the controller is further configured to:
obtain device-related information of the audio device, and send a waking-up instruction to the audio device to cause the audio device to enter the power-on state;
obtain device-related information of the other external devices among the plurality of external devices, and send a waking-up instruction to each of the other external devices to cause each of the other external devices to enter the power-on state;
determine whether a logical address of a first external device is a logical address for an audio device;
in response to the logical address of the first external device being the logical address for the audio device, place the logical address of the first external device into a first list;
in response to the logical address of the first external device being not the logical address for the audio device, place the logical address of the first external device into a second list
check whether there is a second audio device in the first list before checking the second list; and
in response to that there is a second audio device in the first list, cause a device information reporting module first collect device-related information of the second audio device according to the logical address of the second audio device in the first list before checking the second list.
