Description

Sound card self-adaptive loading method and system

Technical Field

The invention relates to the technical field of electronic information, in particular to a sound card self-adaptive loading method and system.

Background

One or 2 or even 3 square chips with pins on 4 sides can be found on the sound card, the area is generally 0.5-1.0 square centimeter, and the area is the codec. codecs are codecs and are mainly responsible for digital/analog signal conversion (DAC) and analog/digital signal conversion (ADC). Whether the audio accelerator is good or the I/O controller is good, the input and the output of the audio accelerator and the I/O controller are pure digital signals, and if the Line Out jack on the sound card is used for outputting signals, the signals need to be converted by a codec on the sound card. It can be said that the quality of the analog input and output of the sound card has an important relationship with the conversion quality of the codec, the audio accelerator or the I/O controller determines the quality of the digital signal inside the sound card, and the codec determines the quality of the analog input and output.

In the field of intelligent equipment, more and more equipment has a multimedia function, and particularly, the voice interaction function gradually becomes standard configuration when the intelligent equipment enters the artificial intelligence era. Among the applications of these functions, audio codec sound card devices play an important role, and because of this, smart devices can only realize playing and recording functions.

Corresponding to the importance of the codec, more and more manufacturers and models are provided; in addition, with the rapid development of the technology, more and more intelligent devices can integrate multiple types of codecs for different scenes. And more devices with different models and the same functions can be integrated with different codecs based on different positioning requirements. For example, for a smart speaker manufacturer a, a codec chip is purchased from a codec chip manufacturer B, and if the codec chips of multiple different models need to be purchased, the manufacturer B needs to respectively maintain multiple sets of codes corresponding to the codec chips of the multiple different models, burn different software, and thus the maintenance cost of the manufacturer is undoubtedly greatly increased. After the codec of the mainboard is changed, the determined codec change software must be recompiled or the software configuration must be changed, and the software can be burned on a corresponding new mainboard for use, which consumes time and labor and increases the cost.

As shown in fig. 1, an embodiment of the present invention provides a method for adaptive loading of a sound card, including:

and S30, loading the current sound card driving program to the codec node to be loaded so as to complete sound card registration. In some embodiments, after completing the sound card registration, the method further comprises: and generating node information for information reading.

In this embodiment, the same set of system software is placed on different motherboards (only different codecs), and the corresponding codecs can be automatically identified, so that different drivers are used to complete the normal function. Therefore, the self-adaptive process is realized, and the production and maintenance cost of manufacturers is greatly reduced.

Fig. 2 is an architecture diagram illustrating polling of codec nodes via an I2C bus, for example, in the smart sound box system. A plurality of codec drivers supported by the intelligent sound box system are pre-configured in the intelligent sound box system, a CPU in the intelligent sound box system is connected to a plurality of codec nodes through a plurality of I2C buses, and when the system is powered on (for example, when a user powers on the intelligent sound box), the codec nodes are polled through an I2C bus, and the obtained identity characteristic information (for example, chip ID) of each codec node is sent to the plurality of drivers configured in the system, and the drivers respectively judge whether the received chip ID is the same as the chip ID of the driver, and if the comparison result is positive, the currently polled codec node corresponds to the current driver, so that the current driver is further loaded to the currently polled codec node; and if the comparison result is negative, the currently polled codec node is not matched with the current driver.

As shown in fig. 3, in some embodiments, polling the plurality of codec nodes via the plurality of I2C buses after the system is powered up and determining whether there is a codec node corresponding to the current sound card driver includes:

s11, polling a plurality of codec nodes on the ith I2C bus, and acquiring the identity characteristic information of the currently polled codec node when polling to one codec node; wherein, I takes values from 1 to n, and n is the number of I2C buses.

Illustratively, the initial value of I is 1, i.e. a plurality of codec nodes on the 1 st I2C bus are polled in the initial condition, and it can be assumed that there are 3 codec nodes on the first I2C bus, the first time the codec node is polled and its chip ID is obtained. The acquired chip ID is then transmitted to the driver built in the system, and step S12 is executed thereafter.

S12, judging whether the identity characteristic information of the current polling codec node corresponds to the current sound card driving program or not; if so, the polling is ended, otherwise, it jumps to step S11.

Exemplarily, after a driver built in the system receives a chip ID, the driver determines whether the chip ID is the same as the chip ID of the driver itself, and if so, indicates that the currently polled codec node corresponds to the current driver; if not, otherwise, and jumping to step S11 to continue polling the second codec node on the 1 st I2C bus, and so on, to perform the subsequent steps, and if no match is determined until the last codec node (the 3 rd codec node on the 1 st I2C bus) on the current I2C bus (e.g., the 1 st I2C bus) is polled, jumping to step S11 to start polling the plurality of codec nodes … … on the 2 nd I2C bus, and so on, to perform polling.

As shown in fig. 4, in some embodiments, the method for adaptively loading a sound card of the present invention further includes:

s41, when the recording request is detected, node information polling is carried out;

s42, if polling to finish the codec node of sound card registration, then starting the codec node of sound card registration for recording;

and S43, if the codec node which completes the sound card registration is not polled, starting the default codec node for recording.

In this embodiment, by configuring the default codec node, even when the system cannot find the sound card registered in the specific codec, recording can be performed based on the default codec node, so that a situation that the recording operation of the user cannot be served when the specific codec is successfully registered due to an uncertain factor can be prevented to a certain extent. Therefore, effective service for the user is guaranteed, and user experience is improved.

The method of the invention is to add an automatic identification part in the software, so that the same software is put on different mainboards (only different codecs), and the corresponding codec can be automatically identified, thereby using different drivers to normally complete the function. Therefore, the self-adaptive process is realized, and the maintenance cost is greatly reduced.

Fig. 5 is a flowchart of a sound card adaptive loading method according to another embodiment of the present invention, which is based on a flow of adding automatic identification after improvement. The method specifically comprises the following steps:

at system power-up for initialization, the codec driver loads in the manner of the i2c device,

a detect on the linux system will poll all devices on all i2c buses,

codec driver in polling, the chip ID of the codec (which may essentially uniquely characterize the codec) is read using i2c communication,

and judging whether the chip id is the chip id of the codec, if the chip id can be read normally and the value is correct, starting the registration of the codec sound card, and generating an information node for information reading after the registration is successful.

If i2c is not passed or chip id is not matched, the codec sound card is not registered, and no codec information node will be generated after polling is finished.

All codec drivers adopt the mode, and the codec driver can be automatically adapted to hardware connection.

And after the system is completely started, the user layer starts the recorder, and judges which codec the hardware is connected with by polling the equipment information of the sound card, so that the corresponding equipment node is opened for normal operation. And if the codec is not found by polling, adopting a default codec equipment node.
