Embodiment Construction

[0025] The embodiments of the present application provide a control method and an electronic device, which solve the technical problem in the prior art that the sound cannot be adjusted before the operating system is loaded.

[0026] The technical solution in the embodiment of the present invention is to solve the above-mentioned problems, and the general idea is as follows:

[0027] After the audio chip is powered on, the state of the sound state identification bit is identified, and an identification result is obtained. When the identification result shows that the sound state identification bit is in a mute state, the sound signal output to the audio output unit is shielded, so it can be used in electronic equipment. Control the audio output in the state before power on.

[0028] In order to better understand the above-mentioned technical solution, the control method of the above-mentioned technical solution will be described in detail below in conjunction with the accompan...

Abstract

The invention discloses a control method and electronic equipment. The control method is applied to an electronic equipment. The electronic equipment includes an audio output unit and an audio chip corresponding to the audio output unit. The audio chip corresponds to a sound state identification bit. The method includes: After the audio chip is powered on, the state of the sound state identification bit is identified to obtain an identification result. When the identification result shows that the sound state identification bit is in a mute state, the sound signal output to the audio output unit is shielded. Through this method, the audio output can be controlled when the electronic device is not turned on.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a control method and electronic equipment. Background technique [0002] The audio / volume of traditional computers is generally output through speakers, headphones or built-in speakers. With the gradual popularity of all-in-one computers, all-in-one computers usually use a built-in speaker design. Similarly, notebook computers also use the same design. However, in the prior art, when the above-mentioned computer, all-in-one computer, and notebook computer are turned on, the audio / volume control is relatively simple and direct. However, along with the popularization of all-in-one machines and the extensive application of multifunctional keyboards, in the prior art, the output of audio / volume can be directly controlled directly through the multiplexed function keys of the keyboard, such as: in the environment of the operating system, it can be directly controlled by Mu...
