Problems solved by technology

[0003] The sound card registration process of the smart terminal will include the registration process of many subsystems. If any of the multiple subsystems fails to register successfully, the entire sound card will be registered fails so that the terminal starts up with a serious problem of silence

Abstract

The embodiment of the invention discloses a sound card control method and device, a terminal and a storage medium. The method comprises the following steps: a first thread executes a sound card registration process, the sound card registration comprises registration of a plurality of subsystems, and a second thread acquires a registration state of a first subsystem of a sound card in the sound card registration process, wherein the taken registration state represents successful registration or failed registration of the first subsystem in the registration; it is determined that the sound cardregistration executed by the first thread fails; and the sound card is triggered to re-register when the registration state of the first subsystem acquired by the second thread in a delayed manner represents that the registration of the first subsystem succeeds.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a sound card control method, device, terminal equipment and storage medium. Background technique [0002] With the development of smart terminal technology, the functions of terminal devices (such as smart phones, tablet computers, wearable smart devices, etc.) are becoming more and more abundant. Among them, the sound card is a structural module commonly used to realize the audio playback function of the terminal device, and whether the sound card can be successfully registered directly affects whether the audio of the terminal device can be played normally. [0003] The registration process of the sound card of the smart terminal will include the registration process of many subsystems. If any of the multiple subsystems fails to register successfully, the entire sound card will fail to register, so that there will be a serious problem of silence after the ...
