[0066] Based on the first embodiment, the present invention also proposes another embodiment:

[0067] After the first audio circuit 201 receives the audio data packet sent by the first external terminal 100, it further includes:

[0068] Step S11: judging whether the second sound card chip U2 is recognized as a system sound card device by the second external terminal 300, if yes, execute step S12; if not, execute step S13;

[0069] Step S12: Continue the step of converting the audio data packet into an audio data stream in pulse code modulation format;

[0070] Step S13: cache the audio data packet into continuous data packet units divided by time periods; confirm that the second sound card chip U2 is recognized as a system sound card device by the second external terminal 300, and convert the cached data packet unit into pulse code modulation format audio data stream, continue the step of transmitting the audio data stream to the second audio circuit 202.

Abstract

The invention provides an audio stream transmitting method and a sound card audio conversion circuit. The audio stream transmitting method is applied to the sound card audio conversion circuit. The sound card audio conversion circuit comprises a first audio circuit and a second audio circuit, both of which are reversely used. The first audio circuit comprises a first pre-set interface and a firstsound card chip which can be recognized by a first external terminal as system sound card equipment. The second audio circuit comprises a second pre-set interface and a second sound card chip which can be recognized by a second external terminal as the system sound card equipment. The first audio circuit receives an audio data package sent by the first external terminal and converts the audio datapackage into audio data streams in the pulse coding modulation format and then transmits the audio data package to the second audio circuit. The second audio circuit converts audio data streams in the pulse coding modulation format into the audio data package and then sends the audio data package to the second external terminal. Therefore, the audio data streams can be transmitted from the firstexternal terminal to the second external terminal.

Description

technical field [0001] The invention relates to information processing technology, in particular to an audio stream transmission method and a sound card audio conversion circuit. Background technique [0002] USB is the abbreviation of Universal Serial Bus (Universal Serial Bus). , Interface standard with PC. With the widespread application of USB technology in modern electronic systems, not only PCs have USB interfaces, but many mobile terminals such as mobile phones, tablet computers, and various smart boxes (various players based on Android or LINUX systems) and include built-in these boxes All smart TVs have a host-function USB interface, and a large number of applications of USB audio devices have been loved and recognized by consumers. [0003] With the development of the existing mobile communication technology, mobile terminals (smart phones, tablet computers, etc.) have become an indispensable part of people's lives, but after the smart terminal is connected to th...
