Abstract

The embodiment of the invention provides an audio playing method and device. The method comprises the steps that whether a current system is a foreground system or not is judged; if it is judged thatthe current system is the foreground system, the audio to be played is added into an audio cache queue, the audio in the audio cache queue is played according to a preset sequence, when the audio cache queue is not empty, the CPU is in an awakening state, and when the audio cache queue is empty, the CPU can enter a dormant state; if it is judged that the current system is not the foreground system, the audio to be played is discarded, that is, the audio to be played is not put into the audio cache queue, so that the background system does not trigger audio playing, the CPU can enter a dormantstate, and the problems that in multi-system processing, the audio of the background system cannot be actually played, and the CPU cannot also enter the dormant state are solved.

Description

technical field [0001] The present invention relates to audio processing technology, in particular to an audio playing method and device. Background technique [0002] With the development of computer technology, more and more operating systems (hereinafter referred to as systems) are born and upgraded. So far, systems have become the most important software used by terminal products or devices. [0003] In the prior art, many terminal products or devices support and use multiple systems, that is, use two or more operating systems. In the specific implementation process, one of the operating systems will run in the foreground, and the other operating systems will run in the background. Wherein, the operating system running in the foreground is a system that can be accessed by the user and may be called a foreground system, while the operating system running in the background is a system that cannot be accessed by the user and may be called a background system. [0004] How...
