- the controller 170 may control the microphone to be turned on when the microphone on trigger condition is satisfied (S43).
- a microphone on trigger condition may be a condition for enabling a microphone.
- a first condition for enabling the microphone may be that the sound output device is switched from a wireless connection device to a wired connection device. Accordingly, the controller 170 may control the microphone to be turned on when the sound output device is switched from a wireless connection device to a wired connection device.
- a second condition for enabling the microphone may be to receive a volume volume change command from the remote control device 200 after the connection with the wireless connection device is released.

- the controller 170 may turn on the microphone and acquire audio recorded for a predetermined time. That is, in the first embodiment, assuming that the user raises the volume by himself when no sound is output, the display apparatus 100 can acquire audio through the microphone without separately adjusting the volume. Accordingly, the controller 170 may obtain audio recorded for a predetermined time after the microphone is turned on. And, accordingly, the audio may include a section in which the volume size is changed according to the volume size change command received from the remote control device 200 . That is, the control unit 170 may acquire audio including a section for changing the volume size according to a command for changing the volume size received from the remote control device 200 after the microphone is turned on.
- the controller 170 turns on the microphone and obtains the recorded audio while adjusting the volume. That is, in the second embodiment, the display device 100 may acquire audio through the microphone while adjusting the volume on its own to check whether sound is output. Accordingly, the controller 170 may automatically sequentially change the volume level after the microphone is turned on, and obtain audio including a section in which the volume level is changed.
- the controller 170 may detect whether or not the volume changes in the captured audio (S50).
- the controller 170 attempts to determine whether the sound is output based on whether or not the volume of the audio has changed. .
- the controller 170 can detect whether or not the volume of the captured audio itself has changed.
- audio may include ambient noise as well as sound output from a sound output device. Accordingly, a volume change may be detected in audio due to a change in noise level even though no sound is output. Accordingly, it is possible to detect a change in volume by filtering only the audio from which noise is removed from the audio.
- the controller 170 can detect whether the volume has changed by filtering the noise-removed audio.
- FIG. 8 is a flowchart illustrating a method of detecting a volume change by filtering audio by a display device according to an embodiment of the present disclosure.

- the first audio may be audio input together with the video, and the second audio may be audio acquired through a microphone in step S40.
- the controller 170 may filter the third audio excluding ambient noise using the first and second audio (S53).
- the controller 170 may compare the first audio with the second audio and filter the third audio excluding ambient noise. Specifically, the controller 170 may acquire ambient noise by removing the first audio from the second audio, and then obtain third audio by removing the ambient noise from the second audio.
- the controller 170 may detect a volume change of the third audio (S55).
- the controller 170 may recognize the third audio as audio obtained by recording the sound output from the sound output device. Accordingly, the controller 170 may detect a change in the volume of the third audio and output a message requesting confirmation of the setting of the sound output device based on the change in the volume of the second audio.
- the controller 170 may continuously output audio through a currently set sound output device (S70).
- the controller 170 determines that sound is being output, and accordingly can continuously output sound through the currently set sound output device.
- the controller 170 may output a message requesting confirmation of the setting of the sound output device (S80).
- the controller 170 may determine a state in which no sound is output, that is, a state in which no sound is output. Accordingly, the controller 170 may output a message requesting confirmation of the setting of the sound output device.
- the message requesting confirmation of the settings of the sound output device may include, for example, text such as "Check whether the current sound output is properly set", but this is merely an example.
- FIG. 9 is an exemplary diagram illustrating a method of outputting a message requesting confirmation of settings of a sound output device by a display device according to an embodiment of the present disclosure.
- the control unit 170 outputs a pop-up 1000 as shown in (a) of FIG. 9, and the pop-up 100 asks, “Can't you hear the current sound? You can include text such as “Please check the sound output.”
- the pop-up 1000 may further include an icon 1001 for moving to a sound output setting menu.
- the controller 170 may display an icon 1001 guiding to a sound output setting menu along with a message requesting confirmation of setting of the sound output device.
- the controller 170 may display a menu 1010 for selecting a sound output device as shown in FIG. 9(b). When a specific device is selected from the menu 1010, the controller 170 can set the selected device as a sound output device.
- the controller 170 may not re-output the message until there is a change in the setting of the sound output device. Since the user may rapidly increase the volume for other reasons, the message is output only once, and thus user inconvenience can be minimized.
- the controller 170 obtains audio through a microphone when the connection with the wireless connection device is disconnected, and outputs a message requesting confirmation of the setting of the sound output device based on the volume change of the audio.
- the display device 100 outputs a message as described above, there is an advantage in guiding the user to quickly recognize the cause of the sound non-output state.
