Summary:The invention provides an implementation method of an audio subsystem, electronic equipment and a computer readable medium. The implementation method of the audio subsystem is applied to mobile equipment running a first operating system and a second operating system. The first operating system and the second operating system run on the main system; the audio subsystem in the first operating system comprises a first audio system framework layer; the audio subsystem in the second operating system comprises a second audio system framework layer; the audio hardware abstraction layer is arranged in the first or second operating system or the main system; the method comprises the following steps: when a first audio system framework layer or a second audio system framework layer requests an audio service from an audio hardware abstraction layer, checking whether a parameter of a corresponding audio channel exists in a preset cache; and under the condition that the corresponding parameters of the audio channel exist
