Problems solved by technology

[0004] Since the configuration information of the sound card is relatively fixed, the data format of the audio supported by it is also relatively fixed. Therefore, when the related technology controls the sound card to transmit audio, it transmits the target audio according to the audio transmission parameters in the configuration information of the sound card, which will result in a transmittable The audio data format is limited and the flexibility is not high

Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0054] With the continuous development of audio transmission technology and the popularization of terminals, most terminals are equipped with sound cards for transmitting audio streams, and there are more and more types of sound cards, and USB sound cards are one of them. Such as a sound card that supports UAC1.0 protocol, a sound card that supports UAC2.0 protocol, and a sound card that supports UAC3.0 protocol. Among them, the UAC1.0 protocol is a USB1.1 audio protocol with a transmission speed of FULL SPEED, and the UAC2.0 protocol is a USB2.0 audio protocol with a transmission speed of HIGH SPEED. The transmission speed of full speed is 12Mbps, and the transmission speed of high speed is 480Mbps.

Abstract

The invention discloses a method, a device and a storage medium for controlling audio transmission by a sound card, belonging to the technical field of audio transmission. The method includes identifying and obtaining configuration information of target sound card; if the configuration information does not match the data format of the target audio to be transmitted, searching for a target interface number and a replaceable setting number supporting the data format of the target audio; if the target interface number and the target replaceable setting number supporting the data format of the target audio are found, the target replaceable setting number and the audio transmission parameters in the configuration information of the data format of the target audio are set according to the foundtarget interface number supporting the data format of the target audio; the target sound card is controlled to transmit the target audio according to the set audio transmission parameters. The methodprovided by the embodiment of the invention can enable the target sound card to transmit the target audio according to the data format of the target audio, thereby expanding the data format of the audio supported by the target sound card and improving the flexibility of audio transmission.

Description

technical field [0001] The invention relates to the technical field of audio transmission, in particular to a method, device and storage medium for controlling sound card transmission of audio. Background technique [0002] With the continuous development of audio transmission technology and the popularization of terminals, most of the terminals are equipped with sound cards for transmitting audio streams, and there are more and more types of sound cards, and USB (Universal Serial BUS, Universal Serial Bus) sound cards are one of them. A sort of. Such as a sound card that supports UAC (USB AUDIO CLASS, USB audio class) 1.0 protocol, a sound card that supports UAC2.0 protocol, and a sound card that supports UAC3.0 protocol. Audio playback can be realized by installing a terminal with a sound card. In order to meet the user's demand for high-quality audio, on the one hand, high-quality audio sources are required; on the other hand, in terms of hardware, sound cards that supp...
